Detailed ways

The following will be combined with the drawings in this specification to clearly and completely describe the technical solutions in this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

In the description of this specification, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of this specification, it should be noted that, unless otherwise clearly specified and limited, "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices. For those of ordinary skill in the art, the specific meanings of the above terms in this specification can be understood in specific circumstances. In addition, in the description of this specification, unless otherwise specified, "multiple" refers to two or more. "And/or" describes the association relationship of associated objects, indicating that three relationships can exist, for example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the associated objects before and after are an "or" relationship.

In the related art, the service platform adopts a fixed system recommendation algorithm to recommend information to users in the form of information distribution, which is often referred to as the push mode based on system algorithm recommendation distribution. The information delivery function focuses on the recommendation and scoring ability of the system recommendation algorithm, and the information is sorted according to the system recommendation algorithm. This is used as the basis for distributing recommended information cards to users. Using the above method, on the one hand, the service platform lacks a medium for dialogue with users, and cannot actively or passively perceive and obtain users' individual preferences, needs and habits; on the other hand, the service platform's recommendation process is relatively simple, and there is no link that combines user personal preferences with system algorithm recommendations; on the other hand, the traditional financial service platform lacks a continuous follow-up feedback mechanism, resulting in the platform's recommendation strategy being unable to be adjusted in time according to changes in user personal preferences. Based on this, in the practice of information recommendation, a large number of users often feedback that they have not found the information of interest to the user after sliding the service page for a long time. The information recommendation method in the related art has certain limitations.

The present specification is described in detail below with reference to specific embodiments.

Please refer to Fig. 1, which is a schematic diagram of a scenario of an information recommendation system provided in this specification. As shown in Fig. 1, the information recommendation system may at least include a client cluster and a service platform 100.

The client cluster may include at least one client, as shown in FIG. 1 , specifically including client 1 corresponding to user 1, client 2 corresponding to user 2, ..., client n corresponding to user n, where n is an integer greater than 0.

Each client in the client cluster may be an electronic device with communication function, including but not limited to: wearable device, handheld device, personal computer, tablet computer, vehicle-mounted device, smart phone, computing device or other processing device connected to a wireless modem, etc. Electronic devices may be called different names in different networks, such as: user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, cellular phone, cordless phone, personal digital assistant (PDA), electronic device in 5G network or future evolution network, etc.

The service platform 100 can be a separate server device, such as a rack-mounted, blade, tower, or cabinet-mounted server device, or a workstation, mainframe computer, or other hardware device with strong computing power; it can also be a server cluster composed of multiple servers, and the servers in the service cluster can be composed in a symmetrical manner, wherein each server has equivalent functions and status in the transaction link, and each server can provide services to the outside independently, and the independent service can be understood as not requiring the assistance of other servers.

In one or more embodiments of the present specification, the service platform 100 may establish a communication connection with at least one client in the client cluster, and complete data interaction in the information recommendation process based on the communication connection.

It should be noted that the service platform 100 and at least one client in the client cluster establish a communication connection through a network for interactive communication, wherein the network can be a wireless network or a wired network, the wireless network includes but is not limited to a cellular network, a wireless local area network, an infrared network or a Bluetooth network, and the wired network includes but is not limited to Ethernet, a universal serial bus (USB) or a controller local area network. In one or more embodiments of the specification, technologies and/or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data (such as a target compressed package) exchanged through a network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec), etc. can also be used to encrypt all or some links. In other embodiments, customized and/or dedicated data communication technologies can also be used to replace or supplement the above data communication technologies.

The information recommendation system embodiment provided in this specification and the information recommendation method in one or more embodiments belong to the same concept. The execution subject corresponding to the information recommendation method involved in one or more embodiments of the specification can be the above-mentioned service platform 100; the execution subject corresponding to the information recommendation method involved in one or more embodiments of the specification can also be the electronic device corresponding to the client, which is determined based on the actual application environment. The implementation process of the information recommendation system embodiment can be found in the following method embodiment, which will not be repeated here.

Based on the scenario diagram shown in FIG1 , the information recommendation method provided by one or more embodiments of this specification is described in detail below.

Please refer to Figure 2, which is a flowchart of an information recommendation method for one or more embodiments of this specification. The method can be implemented by a computer program and can be run on an information recommendation device based on the von Neumann system. The computer program can be integrated into an application or run as an independent tool application. The information recommendation device can be a service platform.

Specifically, the information recommendation method includes:

S102: Determine information preference category signature information of a target user using a preference category inquiry mode, determine at least one information recommendation card for the target user based on the information preference category signature information, and display a transaction service page including the information recommendation card;

The preference category inquiry mode refers to determining the user's preference category (which can be an interest category or a subcategory under an interest category) through human-computer interactive inquiry. It can be understood as a mode or mechanism that determines the user's browsing intention through human-computer interactive inquiry to determine the preference category and recommend relevant preference cards to the user.

The information preference category tag information refers to one or more information preference categories determined for the target user. Usually, one or more subcategory tags may correspond to an information category.

The interactive inquiry involved in the preference category inquiry mode refers to the intention inquiry interaction of the recommending user on the reference category items. The interactive inquiry methods include but are not limited to clicking, reading, interacting, etc. to determine the user's preference category (which can be an interest category or a subcategory under an interest category). Using the preference category inquiry mode, one or more information preference categories of the target user can be determined, thereby obtaining the preference category signature information.

The information recommendation card is a card container for carrying recommended information. The recommended information is displayed to the user in the form of an information recommendation card.

In this specification, the recommended information in the information recommendation card includes but is not limited to information types such as video, image, text and voice.

The transaction service page is the functional page of the transaction service provided to the outside by the service platform involved in this specification.

Optionally, transaction services include but are not limited to financial transaction services, shopping transaction services, express delivery transaction services, etc.;

Specifically, on the one hand, the service platform first scores and sorts the "service supply information cards" based on the information recommendation algorithm, preliminarily determines the initial information cards for sorting, uses the preference category query mode to determine the target user's information preference category signature information, and then uses the information preference category signature information to determine the information recommendation card for the target user. Determine the transaction service page containing the information recommendation card, and display the transaction service page to the target user. For example, the service platform sends the transaction service page data to the user terminal used by the target user, and the user terminal displays the transaction service page based on the transaction service page data.

In a specific implementation scenario, as shown in FIG3 , FIG3 is a schematic diagram of a scenario of transaction service page processing. A user enters a transaction service application provided by a service platform for browsing. The recommendation system of the service platform uses an information recommendation algorithm to score the “service supply information card” to obtain a card recommendation score. Based on the card recommendation score, the “service supply information card” is ranked for overall recommendation. Then, these “service supply information cards” (the service supply information card contains transaction service information to recommend it to users for reference) are recalled. The “service supply information card” is the initial information card preliminarily determined by the platform using the information recommendation algorithm. Then, the “service supply information card” is subjected to algorithm rough sorting intervention processing, that is, the information recommendation algorithm is called to score and sort the information category tags through the algorithm, and the priority order of the information category tags between the information category tags is arranged. At this time, the information preference category tag has the highest priority, and then the initial information card is allocated under each information category tag.

Furthermore, the initial information cards under each information category tag are finely sorted and intervened: the preference category tag information is queried from the DB (database), and the information recommendation cards of interest in the initial information cards are filtered out from the initial information cards according to the user preference subcategory tags in the preference category tags selected by the user. The rest are ordinary system recommendation cards. At this time, the initial information cards are divided into information recommendation cards of interest and ordinary system recommendation cards, and then the priority of the information recommendation cards signed under one or more information category tags is increased to make the priority of the information recommendation cards signed under the information category tags higher than the ordinary system recommendation cards. The ordinary system recommendation cards are ranked after the information recommendation cards according to the card recommendation score. After completing the above operations, the other information data of the complete information card is finally assembled to complete the update of the transaction service page, and the updated transaction service page is returned to the user terminal used by the target user.

Furthermore, if the preference category tag information does not contain a user preference subcategory tag under the preference category tag, the initial information cards under each information category tag are sorted according to the card recommendation score, and finally the other information data of the completed information card is assembled to complete the update of the transaction service page, and the updated transaction service page is returned to the user terminal used by the target user. In this case, usually the user has only selected the information preference category tag through the preference category inquiry mode, but has not inquired and selected the user preference subcategory tag. The subsequent service platform can perform subsequent page updates and selection of user preference information categories based on the preference category inquiry mode.

S104: In response to the target user's page browsing operation on the transaction service page, determining a reference subcategory tag set under the reference information category tag through the preferred category inquiry mode, and displaying the reference subcategory tag set on the transaction service page;

The page browsing operation is the operation of browsing page information made by the target user after performing a transaction service page through the user terminal. The user terminal generates the page browsing operation and sends the page browsing operation to the service platform. At this time, the service platform can receive the page browsing operation;

The preference category inquiry mode can also be called the KYC (Know Your Compensation) mode. The preference category inquiry mode varies according to the user's inquiry timing. The user's inquiry timing can be understood as the timing of determining the user's preference category (which can be an interest category or a subcategory under an interest category) through human-computer interactive inquiry. For example, it can be called the first preference category inquiry mode, the second preference category inquiry mode, and the third preference category inquiry mode. It is easy to understand that the first preference category inquiry mode can be referred to as the pre-KYC mode, the second preference category inquiry mode can be referred to as the in-process KYC mode, and the third preference category inquiry mode can be referred to as the post-KYC mode. Each KYC mode appears at different times, complementing each other and improving the user's KYC interest preference label selection.

Indicatively, by monitoring the page browsing operation of the target user on the transaction service page through the preference category inquiry mode, the "reference subcategory tag set under the reference information category target signature" of this "interactive inquiry user" can be determined through the preference category inquiry mode during the page browsing process. The service platform displays the reference subcategory tag set under the reference information category target signature on the user-side transaction service page, so that users can click on the pushed reference subcategory tags during page browsing to continuously update or maintain their personal interest preference tags (also known as user preference subcategory information tags) or information preference category tags, and realize a user-centered customized information recommendation service. This preference category inquiry mode can continuously track the user's intentions to maintain the user's information preferences and realize accurate information recommendation. Let each user have his own exclusive counter-style leading service, greatly improve the user's satisfaction with the platform's transaction services, reflect the customization and exclusivity of the leading platform, and also help the stable growth of transaction services.

The information category tag is the root information category divided according to the information characteristics. Under the information category tag, there are one or more sub-information categories. The sub-information category can be called the information sub-category tag;

Information sub-category label: Each recommended information card (such as a service information card) corresponds to an attribute under a specific information category label (which can be called a KYC category label). Multiple information sub-category labels (which can be called KYC sub-category labels) belong to a higher-level information category label (which can be called a KYC parent category label) at the same time.

The reference information category tag (which can be called the kyc major category tag) is an information category tag determined by the preference category query mode during the user's page browsing process. At this time, the reference information category tag is not directly displayed, but the reference subcategory tag set under the reference information category tag is displayed. The reference subcategory tag set includes one or more reference subcategory tags. The reference information category tag can be determined according to the category tag determination rule of the preset preference category query mode, and the category tag determination rule is not limited here.

S106: In response to the target user's subcategory label selection operation for the reference subcategory label set, determining at least one user preferred subcategory label;

The sub-category label selection operation refers to the selection operation made by the target user for the user's preferred sub-category label from the reference sub-category label set;

The user preference subcategory label refers to the interest information subcategory label of the target user determined based on the subcategory label selection operation.

The preference subcategory label information includes one or more user preference subcategory labels;

The information preference category tag information includes one or more information preference category tags;

Illustratively, the target user browses a transaction service page through a user terminal, the transaction service page displays a reference sub-category tag set, the target user inputs a sub-category tag selection operation for a user-preferred sub-category tag on the user terminal, the user terminal sends the sub-category tag selection operation to the service platform, and the service platform determines at least one user-preferred sub-category tag in response to the target user's sub-category tag selection operation for the reference sub-category tag set;

Optionally, the user preference subcategory tag information may be updated based on the user preference subcategory tag, and the information preference category tag to which the user preference subcategory tag belongs may be determined, and the information preference category tag to which the user preference subcategory tag belongs may be updated into the information preference category tag information.

S108: Recall at least one preference information recommendation card based on the user preference subcategory tag, and update the transaction service page with recommendation information based on the preference information recommendation card.

In a specific implementation scenario, when the target user browses the user transaction page on a daily basis, the in-process KYC mode or the post-KYC mode in the preference category inquiry mode is triggered. The information category labels (information category labels and information subcategory labels under the information category labels) are scored and sorted through the algorithm system of the service platform, and the KYC subcategory labels under the KYC major category labels not selected by the target user are decided. These labels are presented to the target user through the in-process KYC mode or the post-KYC mode in the preference category inquiry mode. At the same time, after the target user enters the subcategory label selection operation, the user's preferred subcategory label is immediately determined, and the preference information recommendation card corresponding to the user's preference subcategory label is recalled. Based on the preference information recommendation card, the display order of the information recommendation cards in the transaction service page is adjusted, thereby completing the update of the recommended information.

In one or more embodiments of the present specification, the service platform adopts a preference category inquiry mode to determine the target user's information preference category signature information, determines an information recommendation card based on the information preference category signature information, generates a transaction service page containing the information recommendation card, and responds to the target user's page browsing operation by determining a reference subcategory tag set under the reference information category signature through the preference category inquiry mode, and displays the reference subcategory tag set on the transaction service page, determines the user's preference subcategory tag in response to the target user's subcategory tag selection operation for the reference subcategory tag set, and recalls the preference information recommendation card based on the user's preference subcategory tag to update the transaction service page with recommended information, thereby realizing a user-centric customized information recommendation service. Using this preference category inquiry mode, the user's intentions can be continuously tracked to maintain the user's information preferences, and accurate information recommendation can be achieved, which greatly improves the user's satisfaction with the platform's transaction services, reflects the customization and exclusivity of the leading platform, and also helps the transaction services to grow steadily.

Please refer to FIG. 4 , which is a flowchart of another embodiment of an information recommendation method proposed in one or more embodiments of this specification. Specifically:

S202: In response to the target user's initial opening operation on the transaction service page, starting a first preference category inquiry mode for the target user, and determining a preference category inquiry area on the transaction service page through the first preference category inquiry mode;

According to some embodiments, the first preference category inquiry mode may be referred to as the pre-KYC mode. In the pre-KYC mode, when a user enters the transaction service page for the first time, a recommended reference information category label is displayed in the preference category inquiry area of the transaction service page. The reference information category label is also a KYC category label form (the user can check it);

Indicatively, when configuring the first preference category inquiry mode, a preference category inquiry area may be set for the transaction service page, and the preference category inquiry area is used to determine the user's preference category - KYC category through a human-computer interactive inquiry method;

S204: Displaying at least one reference information category tag in the preference category inquiry area, and determining information preference category tag information of the target user in response to a category tag selection operation of the target user on the reference information category tag.

Exemplarily, as shown in Figure 5, Figure 5 is an interface diagram of a preference category inquiry mode. As shown in Figure 5, taking the transaction service page as a financial transaction service page as an example, the user enters the financial transaction service page for the first time to start the first preference category inquiry mode (pre-KYC mode) for the target user. The first preference category inquiry mode is associated with a preference category inquiry area on the transaction service page. In the preference category inquiry area, users and target users conduct interactive inquiries on preference categories. The preference category inquiry area can display user-selectable KYC category labels (that is, reference information category labels). As shown in Figure 5, the preference category inquiry area displays "Selecting Good Financial Products", "Interpreting Market Trends", "Customized Configuration Plans", "Self-Selected Position Suggestions", "Receive Exciting Benefits", "Selected Popular Content" and so on.

The target user can select one or more information preference category tags from the several reference information category tags provided. One or more information preference category tags constitute the information preference category tag information. Subsequently, when the target user uses the user terminal to browse the transaction service page of the service platform, only the kyc category tag floors that the user has selected to be interested will be displayed.

S206: Determine at least one information recommendation card for the target user based on the information preference category tag information;

Exemplarily, as shown in FIG6 , the figure is a schematic diagram of a processing scenario of a first preference category inquiry mode. When a user enters the transaction service page for the first time, the first preference category inquiry mode for the target user is started, and the user is provided with a reference information category tag to select. Subsequently, when the user browses the transaction service page, the kyc category tag option in the prior kyc mode is checked, and information preference category tag information including one or more kyc category tag options is determined. At this time, the service platform will save and record the information preference category tag information (such as the user kyc category tag preference information shown in FIG6 ), and determine at least one information recommendation card for the target user based on the information preference category tag information.

The recommendation system of the service platform uses the information recommendation algorithm to score the "service supply information card" to obtain the card recommendation score, and then recommends and sorts the "service supply information card" as a whole based on the card recommendation score, and then recalls these "service supply information cards" (the service supply information card contains transaction service information to recommend it to users for reference). The "service supply information card" is the initial information card preliminarily determined by the platform using the information recommendation algorithm before; then the "service supply information card" is subjected to algorithm rough sorting intervention processing, that is, the information recommendation algorithm is called to score and sort the information category tags through the algorithm, and the priority order of the information category tags between the various information category tags is arranged. At this time, the information preference category tag has the highest priority, and then the initial information card is allocated under each information category tag;

Furthermore, the initial information cards under each information category tag are sorted and intervened: the preference category tag information is queried from the DB (database), and the information recommendation cards of interest in the initial information cards are filtered out according to the user preference subcategory tags in the preference category tag selected by the user. The remaining cards are ordinary system recommendation cards;

S208: loading an information preference category area and an information recommendation card area on the transaction service page, displaying the information preference category tags in the information preference category tag information in the information preference category area, and displaying the information recommendation card in the information recommendation card area;

Exemplarily, at this time, based on the information preference category tag information, the initial information cards are divided into information recommendation cards of interest and general system recommendation cards, and the transaction service page can be configured with an information preference category area and an information recommendation card area; one or more information preference category tags in the information preference category tag information are displayed in the information preference category area, and information recommendation cards are displayed in the information recommendation card area;

Optionally, the information recommendation card area may set the information recommendation cards corresponding to the information preference category tags to be displayed in columns, and distribute the initial information cards to the sub-card areas corresponding to the information category tags in the information recommendation card area.

Optionally, the priority of the information recommendation cards signed by one or more information-related targets is then increased, so that the priority of the information recommendation cards signed by information-related targets is higher than that of ordinary system recommendation cards. Ordinary system recommendation cards are ranked after the information recommendation cards according to the card recommendation scores. After completing the aforementioned operations, other information data of the information cards are finally assembled to complete the update of the transaction service page, and the updated transaction service page is returned to the user terminal used by the target user.

S210: In response to the target user's category tag modification operation on the information preference category tag in the information preference category area, determining to modify the information preference category tag, and updating the information preference category tag information based on the modified information preference category tag;

Specifically, as shown in FIG6 , when the target user enters the page for the second time and browses the page, he can also modify the information preference category label (which can be called the KYC category label floor) he wants to display according to his own preferences. Specifically, in response to the target user's category label modification operation on the information preference category label in the information preference category area, it is determined to modify the information preference category label, and the information preference category label information is updated based on the modified information preference category label.

For example, during daily page browsing, if the user is not satisfied with the information preference category tag (kyc major interest preference tag) selected for the first time and wants to modify (add or delete) the kyc tag, the user can select the kyc category tab list option and re-select the kyc personal interest preference tag by modifying the kyc category tab list. That is, the target user triggers the category tag modification operation for the information preference category tag according to the information preference category list option in the information preference category area, determines to modify the information preference category tag, and updates the information preference category tag information based on the modified information preference category tag.

S212: In response to the target user's target card operation on the reference information recommendation card in the transaction service page, determining a reference information subcategory tag corresponding to the reference information recommendation card, determining that the reference information subcategory tag is a non-user preference type, and deleting the reference information subcategory tag in the information preference category tag information based on the non-user preference type;

Reference information recommendation cards can be understood as information recommendation cards that target users are not interested in;

The target card operation can be understood as the target user's disinterested operation on the reference information recommendation card. At this time, the service platform can determine the reference information subcategory label corresponding to the reference information recommendation card, determine that the reference information subcategory label is a non-user preference type, and delete the reference information subcategory label in the information preference category label information based on the non-user preference type;

In one or more embodiments of the present specification, the service platform uses a preference category inquiry mode to determine the information preference category tag information corresponding to the target user's initial opening operation, determines the information recommendation card based on the information preference category tag information to generate a transaction service page, determines the reference subcategory tag set under the reference information category tag through the preference category inquiry mode after the target user enters the page browsing operation, and displays the reference subcategory tag set on the transaction service page, determines the user preference subcategory tag in response to the target user's subcategory tag selection operation for the reference subcategory tag set, recalls the preference information recommendation card based on the user preference subcategory tag to update the transaction service page with recommended information, and guides the target user through the category tag modification operation, target card operation, etc. through the preference category inquiry mode to realize a user-centered customized information recommendation service, and uses this preference category inquiry mode to continuously track the user's intention to maintain the user's information preference and realize accurate information recommendation. Let each user have his own exclusive counter-style leading service, greatly improve the user's satisfaction with the platform's transaction service, reflect the customization and exclusiveness of the leading platform, and also help the stable growth of transaction services.

Please refer to FIG. 7 , which is a flowchart of another embodiment of an information recommendation method proposed in one or more embodiments of this specification. Specifically:

S302: Displaying a transaction service page including the information recommendation card;

For details, please refer to the method steps in other embodiments of this specification, which will not be repeated here.

S304: starting a second preference category inquiry mode for the target user, determining a first subcategory tag set under a first information category target tag, and displaying the first subcategory tag set on the transaction service page, wherein the first information category tag is different from the information preference category tag in the information preference category area;

According to some embodiments, the second preference category inquiry mode may be referred to as the in-process KYC mode. In the in-process KYC mode, when a user browses a transaction service page not for the first time, the first subcategory tag set under the first information category tag is displayed on the transaction service page, and the first information category tag is different from the information preference category tag in the information preference category area; it can be understood that the second preference category inquiry mode displays the first subcategory tag set under the KYC major category (that is, the information preference category tag) that does not belong to the user's preference (not clicked to select), and the first subcategory tag set may be displayed in the form of a KYC subcategory tag form;

The in-process kcy mode will only display the kyc sub-category tags under the unselected kyc major category tags. The in-process kcy mode helps recommend users more potential kyc sub-category tags (i.e., first sub-category tags) that may be of interest. Once the user checks the kyc sub-category tags under the unpreferred kyc major category tags for the first sub-category tag set, the checked kyc sub-category tags under the unpreferred kyc major category tags will be used as the user's preferred sub-category tags.

Update user preference subcategory tag information based on user preference subcategory tag, and update information preference category tag information based on information category tag corresponding to user preference subcategory tag. It can be understood that the kyc subcategory tag and the kyc category tag to which the kyc subcategory tag belongs will be saved and recorded by the platform, and the subsequent extensible transaction service page will immediately present the information card associated with the kyc subcategory tag to the user;

S306: Start a third preference category inquiry mode for the target user, determine a second subcategory tag set under the information preference category target signature, and display the second subcategory tag set on the transaction service page, wherein the second subcategory tag set includes at least one information preference subcategory tag that is not selected by the target user.

According to some embodiments, the third preference category inquiry mode may be referred to as the post-KYC mode. In the post-KYC mode, when a user is not browsing the transaction service page for the first time, the second subcategory label set under the information preference category signature is displayed on the transaction service page. It can be understood that in the pre-KYC mode, the user only selected the information preference category signature, and for the sake of efficient and convenient information recommendation, no detailed inquiry was made on the subcategory labels under the information preference category signature.

The third preference category inquiry mode displays the second subcategory tag set under the KYC category (that is, the information preference category tag) that belongs to the user's preference (not clicked to select). The second subcategory tag set can be displayed in the form of a KYC subcategory tag form; the third preference category inquiry mode is to help users determine the KYC subcategory tag set under the known preferred KYC category tag, and ensure that each time the platform recalls the recommended card, it gives priority to including the user's preferences and the desired KYC subcategory tag attributes.

Exemplarily, as shown in FIG8 , FIG8 is a scene diagram of a preference category inquiry mode provided in this specification. The target user is not browsing the transaction service page for the first time. One way may be to display the first sub-category tag set under the first information category tag in the transaction service page, and the first information category tag is different from the information preference category tag in the information preference category area; it can be understood that the second preference category inquiry mode displays the first sub-category tag set under the KYC category (that is, the information preference category tag) that does not belong to the user's preference (not clicked to select), and one way may be to display the second sub-category tag set under the information preference category tag in the transaction service page;

The target user selects one or more target KYC subcategory label options of the first/second subcategory label set recommended by the in-process KYC model. The target KYC subcategory label option is now used as the user's preferred subcategory label. The service platform saves or modifies the user's preferred subcategory label information, and can also modify the information preference category label information.

S308: In response to the target user's subcategory tag selection operation for the reference subcategory tag set, determine at least one user preference subcategory tag, recall at least one preference information recommendation card based on the user preference subcategory tag, and update the transaction service page with recommendation information based on the preference information recommendation card.

updating the user preference subcategory label information and the information preference category label information based on the user preference subcategory label, wherein the reference subcategory label set includes at least one of a first subcategory label set and a second subcategory label set;

In a specific implementation scenario, when the target user browses the user transaction page on a daily basis, the in-process KYC mode or the post-process KYC mode in the preference category inquiry mode is triggered. The information category labels (information category labels and information subcategory labels under information category labels) are scored and sorted by the algorithm system of the service platform, and the KYC subcategory labels under the KYC major category labels not selected by the target user are determined. After the target user enters the subcategory label selection operation, the user's preferred subcategory label is immediately determined, and the preferred subcategory label information is updated. The service information card of the transaction service page is recalled, and it is determined whether the service information card has a preference subcategory label based on the preference subcategory label information, that is, the user preference information card and the non-user preference information card are screened out;

Before arranging and configuring the user preference information card to the non-user preference information card in the transaction service page, the "personal preference card corresponding to the user preference subcategory label" can be immediately placed on top to increase the priority. Specifically, the user preference information card can be multiple, and each user preference information card corresponds to a different subcategory preference label. The user preference information cards are arranged according to the preference label recording date of the subcategory preference label corresponding to the user preference information card to obtain a user preference information card sequence, and the user preference information card sequence is placed on top to increase the priority (first sorting process); at the same time, for the non-user preference information card, the original information recommendation algorithm is used to determine the information recommendation score of the non-user preference information card, and the multiple non-user preference information cards are sorted according to the information recommendation score to obtain a non-user preference information card sequence (second sorting process), and the non-user preference information card sequence is arranged after the user preference information card sequence, thereby completing the page update process of the transaction service page after the user enters the subcategory label selection operation.

In a feasible implementation manner, after determining at least one user preference subcategory tag, the service platform may perform the following:

A2: The service platform writes the user preference subcategory tag into the preference subcategory tag information;

A4: The service platform determines the target information category tag corresponding to the user preference subcategory tag, and if the target information category tag does not exist in the information preference category tag information, writes the target information category tag into the information preference category tag information.

The above process completes the process of pairing preference subcategory label information and information preference category label information based on user preference subcategory labels.

S310: In response to the target user's page refresh operation on the transaction service page, the service information cards in the transaction service page are recalled, user preference information cards and non-user preference information cards are determined based on preference subcategory label information, the user preference information cards are arranged before the non-user preference information cards in the transaction service page, and a first sorting process is performed on the user preference information cards in the transaction service page based on the preference label recording date and a second sorting process is performed on the non-user preference information cards in the transaction service page based on the information recommendation points.

The second preference category inquiry mode and the third preference category inquiry mode both support page refresh logic. After browsing the transaction service page, the target user is not satisfied with the service information card recommended by the transaction service page. The target user can input a page refresh operation for the transaction service page on the user end and send it to the service platform. As shown in FIG8 , the service platform responds to the target user's page refresh operation for the transaction service page, recalls the service information card in the transaction service page, determines the user preference information card and the non-user preference information card based on the preference subcategory label information, arranges the user preference information card before the non-user preference information card in the transaction service page, and performs a first sorting process on the user preference information card in the transaction service page based on the preference label recording date and performs a second sorting process on the non-user preference information card in the transaction service page based on the information recommendation points.

Specifically, after the page refresh operation, the service platform recalls the service information card of the transaction service page, queries the preference subcategory tag information to determine whether the service information card has the preference subcategory tag, that is, filters out the user preference information card and the non-user preference information card in the page;

Before arranging and configuring the user preference information card to the non-user preference information card in the transaction service page, the "personal preference card corresponding to the user preference subcategory label" can be immediately placed on top to increase the priority. Specifically, the user preference information card can be multiple, and each user preference information card corresponds to a different subcategory preference label. The user preference information cards are arranged according to the preference label recording date of the subcategory preference label corresponding to the user preference information card to obtain a user preference information card sequence, and the user preference information card sequence is placed on top to increase the priority (first sorting process); at the same time, for the non-user preference information card, the original information recommendation algorithm is used to determine the information recommendation score of the non-user preference information card, and the multiple non-user preference information cards are sorted according to the information recommendation score to obtain a non-user preference information card sequence (second sorting process), and the non-user preference information card sequence is arranged after the user preference information card sequence, thereby completing the page update process of the transaction service page after the user inputs a page refresh operation.

In one or more embodiments of the present specification, the service platform uses the first preference category inquiry mode to determine the information preference category tag information corresponding to the target user's initial opening operation, determines the information recommendation card based on the information preference category tag information to generate a transaction service page, and after the target user enters the page browsing operation, determines the reference subcategory tag set under the reference information category tag through the second or third preference category inquiry mode, and displays the reference subcategory tag set on the transaction service page, determines the user preference subcategory tag in response to the target user's subcategory tag selection operation for the reference subcategory tag set, and recalls the preference information recommendation card based on the user preference subcategory tag to update the transaction service page with recommended information, so as to realize a user-centered customized information recommendation service, and uses this preference category inquiry mode to continuously track the user's intention to maintain the user preference tag and realize accurate information recommendation. Let each user have his own exclusive counter-style leading service, greatly improve the user's satisfaction with the platform's transaction service, reflect the customization and exclusive sense of the leading platform, and also help the stable growth of transaction services.

Please refer to FIG9 , which is a flowchart of another embodiment of an information recommendation method proposed in one or more embodiments of this specification. Specifically:

S402: In response to a sub-category label selection operation of the target user on the reference sub-category label set, determining at least one user preferred sub-category label;

Optionally, in response to the target card operation of the target user on the reference information recommendation card in the transaction service page, determining the reference information subcategory tag corresponding to the reference information recommendation card, determining that the reference information subcategory tag is a non-user preference type, and setting the preference subcategory tag state to a preference subcategory tag invalid state when the reference information subcategory tag is a preference subcategory tag;

S404: configuring a preference tag validity period for the user preference subcategory tag, and performing preference subcategory tag management on the user preference subcategory tag within the preference tag validity period.

In this specification, after determining the user's preferred subcategory tag according to the subcategory tag selection operation of the target user, the user's preferred subcategory tag is configured with a preference tag validity period, and the preference subcategory tag is subsequently managed based on the preference tag validity period;

Information subcategory tags within the validity period of the preference tag can be considered as valid preference subcategory tags, and kyc subcategory tags outside the validity period of the preference tag can be considered as invalid preference subcategory tags.

Optionally, in order to adapt to the changes in the user's preferred kyc subcategory labels that may occur over time, the kyc subcategory labels can be configured with a continuous positive/negative feedback mechanism, as shown in Figure 10, which is a scenario diagram of a feedback mechanism for a preference category query mode. Exemplarily, the following methods can be used:

B2: based on the detection of the preference subcategory label status corresponding to the user preference subcategory label;

The preference subcategory label status includes a preference subcategory label valid status and a preference subcategory label invalid status;

As shown in FIG10 , the validity period of the preference tag is shown as the freshness period in FIG10 . Assuming that the validity period of the preference tag is x days, further verification is performed; within the freshness period of x days, the preference subcategory tag state is the preference subcategory tag valid state, and after the freshness period of x days, the preference subcategory tag state is the preference subcategory tag invalid state;

B4: If the preference subcategory tag state is the preference subcategory tag valid state, the preference information recommendation card corresponding to the user preference subcategory tag is subjected to priority information recommendation processing, and the preference category inquiry mode for the target user is initiated to recommend the target user a recommended preference subcategory tag set associated with the user preference subcategory tag, and the recommended preference subcategory tag set is used as the reference subcategory tag set and the step of displaying the reference subcategory tag set on the transaction service page is performed;

Positive feedback mechanism: After the user clicks to select the kyc subcategory tag as the preference tag, a validity period of the preference tag of x days will be set (the shelf life in Figure 10). During the shelf life, the preference information recommendation card corresponding to the user's preference subcategory tag will be given priority information recommendation processing. For example, the kyc subcategory tag card selected by the user will be strongly pinned to the top, and the recommended preference subcategory tag set associated with the user's preference subcategory tag (kyc subcategory tag) will be recommended to provide the user with more choices. That is, the recommended preference subcategory tag set is used as the reference subcategory tag set and the step of displaying the reference subcategory tag set on the transaction service page is executed;

Furthermore, after the validity period of the preference tag has passed, the kyc sub-category tag in the reference sub-category tag set can be used through the preference category query mode. If the user clicks on the kyc sub-category tag information card, it will be considered that the user is interested in the kyc sub-category tag, and the kyc information card under the kyc sub-category tag will continue to be pinned;

B6: If the status of the preference subcategory label is an invalid status of the preference subcategory label, the information card operation frequency of the target user on the preference information recommendation card corresponding to the user preference subcategory label is monitored within a preset period, and the preference subcategory label status extension management is performed on the user preference subcategory label based on the information card operation frequency.

Negative feedback mechanism: After the user's preferred kyc sub-category tag has passed its shelf life, the status of the preferred sub-category tag is invalid. If the user has been operating the information card of the kyc sub-category tag under the preferred kyc sub-category tag displayed by the service platform less frequently, the service platform determines that the user is not interested in the kyc sub-category tag, and resets the kyc classification tag to a regular sub-category tag state. At the same time, the kyc sub-category tag can appear on the user's browsing page for the user to reselect. In addition, when browsing the page, the user can actively press and hold the information card displayed at that time and click the pop-up "Not Interested" button to ensure that the user will not receive the information card of the kyc sub-category tag attribute in the future.

Optionally, the performing preference subcategory tag state extension management on the user preference subcategory tag based on the information card operation frequency may be performed in the following manner:

1. If the operation frequency of the information card is greater than the operation frequency threshold, the preference subcategory tag state of the user preference subcategory tag is extended;

The operation frequency threshold is the threshold for the operation frequency of the information card;

2. If the operation frequency of the information card is less than or equal to the operation frequency threshold, the preference subcategory tag state of the user preference subcategory tag is set to the regular subcategory tag state, and the regular subcategory tag in the regular subcategory tag state is added to the reference subcategory tag set.

If the frequency of operation on the information card of the kyc subcategory tag under the preferred kyc subcategory tag displayed by the service platform is always low, the service platform determines that the user is not interested in the kyc subcategory tag, and resets the kyc classification tag to the normal state, and adds the regular subcategory tag in the regular subcategory tag state to the reference subcategory tag set. At this time, the kyc subcategory tag can appear in the user's browsing page for the user to reselect.

In one or more embodiments of the present specification, the service platform uses the first preference category inquiry mode to determine the information preference category tag information corresponding to the target user's initial opening operation, determines the information recommendation card based on the information preference category tag information to generate a transaction service page, and after the target user enters the page browsing operation, determines the reference subcategory tag set under the reference information category tag through the second or third preference category inquiry mode, and displays the reference subcategory tag set on the transaction service page, determines the user preference subcategory tag in response to the target user's subcategory tag selection operation for the reference subcategory tag set, and recalls the preference information recommendation card based on the user preference subcategory tag to update the transaction service page with recommended information, so as to realize a user-centered customized information recommendation service, and uses this preference category inquiry mode and the positive and negative feedback mechanism corresponding to the preference category inquiry mode to continuously track the user's intention to maintain the user preference tag and realize accurate information recommendation. Let each user have his own exclusive counter-style leading service, greatly improve the user's satisfaction with the platform's transaction service, reflect the customization and exclusiveness of the leading platform, and also help the stable growth of transaction services.

Responding to target card operation of the target user on a reference information recommendation card in the transaction service page, determining a reference information sub-class label corresponding to the reference information recommendation card, determining that the reference information sub-class label is of a non-user preference type, and deleting the reference information sub-class label in the information preference class label information based on the non-user preference type; and/or the number of the groups of groups,

And in response to page refreshing operation of the target user for the transaction service page, recalling service information cards in the transaction service page, determining user preference information cards and non-user preference information cards based on preference subclass tag information, arranging and configuring the user preference information cards to be before the non-user preference information cards in the transaction service page, performing first sorting processing on the user preference information cards in the transaction service page based on preference tag record dates, and performing second sorting processing on the non-user preference information cards in the transaction service page based on information recommendation scores.

7. The method of claim 1, further comprising, after said determining at least one user preference subclass label:

And configuring a preference tag validity period for the user preference sub-category tag, and managing the preference sub-category tag based on the preference tag validity period.

8. The method of claim 7, the managing the preference subclass label based on the preference label validity period comprises:

Detecting a preference subclass tag state corresponding to the user preference subclass tag based on the preference tag validity period;

If the preference subclass tag state is the preference subclass tag valid state, performing priority information recommendation processing on preference information recommendation cards corresponding to the user preference subclass tags, starting a preference category query mode aiming at the target user, recommending a recommendation preference subclass tag set associated with the user preference subclass tag to the target user, taking the recommendation preference subclass tag set as the reference subclass tag set, and executing the step of displaying the reference subclass tag set on the transaction service page;

If the preference sub-class label state is the preference sub-class label failure state, monitoring the information card operation frequency of the target user on the preference information recommendation card corresponding to the user preference sub-class label in a preset period, and carrying out preference sub-class label state delay management on the user preference sub-class label based on the information card operation frequency.

9. The method of claim 8, the preference subclass tag status deferred management of the user preference subclass tag based on the information card operating frequency, comprising:

If the operation frequency of the information card is larger than an operation frequency threshold, carrying out preference subclass tag state delay processing on the user preference subclass tag;

If the operation frequency of the information card is smaller than or equal to an operation frequency threshold value, setting a preference sub-class label state of the user preference sub-class label to be a normal sub-class label state, and adding a normal sub-class label which is the normal sub-class label state into the reference sub-class label set.

10. An information recommendation apparatus, the apparatus comprising:

The page processing module is used for determining information preference category label information of the target user by adopting a preference category query mode, determining at least one information recommendation card aiming at the target user based on the information preference category label information, and displaying a transaction service page containing the information recommendation card;

The set processing module is used for responding to the page browsing operation of the target user for the transaction service page, determining a reference sub-class label set under the reference information type target sign through the preference category query mode, and displaying the reference sub-class label set on the transaction service page;

The tag processing module is used for responding to the sub-class tag selection operation of the target user for the reference sub-class tag set and determining at least one user preference sub-class tag;

And the information updating module is used for recalling at least one preference information recommendation card based on the user preference subclass tag information, and updating recommendation information of the transaction service page based on the preference information recommendation card.
