Description

Arrival behavior detection method and device based on interest point information and computer equipment

Technical Field

The present application relates to the field of computer technologies, and in particular, to a method and an apparatus for detecting arrival behavior based on point of interest information, and a computer device.

Background

Currently, an information sharing platform can provide sharing and query services of local living information for users. For example, after experiencing a food in a store, a user issues comment information on the store through an information sharing platform. Before going to the store for consumption, other users can inquire the comment information of the store through the information sharing platform, so that the store can be quickly and conveniently known.

Since the content released after the user arrives at the store for experience has a reference value, the user's store-arrival behavior can be used as a reference when determining the quality of the released content. In the related art, a user can manually locate a store by performing an interactive operation, and issue comment information in a comment interface of the store. Correspondingly, the information sharing platform determines that the user arrives at the store based on the interactive operation implemented by the user, and associates the store with comment information issued in a comment interface of the store.

In the above process, the user can manually locate the store by implementing the interactive operation under the condition that the user does not arrive at the store for experience, and accordingly, the information sharing platform determines that the user arrives at the store, and the accuracy of the store behavior judgment is low.

Or the method for detecting the arrival behavior based on the interest point information provided by the embodiment of the application is implemented through interaction between the terminal and the server, and the embodiment of the application is not limited to the method.

Fig. 2 is a flowchart of a method for detecting arrival behavior based on point of interest information according to an embodiment of the present application. Referring to fig. 2, this embodiment will be briefly described taking a server as an execution subject, and includes:

201. the server acquires a multimedia resource uploaded by the user account based on the first interest point, wherein the multimedia resource carries first position information, and the first position information is used for indicating the position when the multimedia resource is shot.

The user uploads the multimedia asset based on the first point of interest to indicate that the multimedia asset is a multimedia asset associated with the first point of interest. Since the multimedia resource photographed after the user arrives at the first interest point has the reference value, it is necessary to detect whether the multimedia resource is photographed by the user arriving at the first interest point, that is, to perform the detection of the arrival behavior.

Optionally, the multimedia asset comprises at least one of an image and a video. The multimedia resource is shot by a user by using a terminal with a shooting function, and the terminal has the authority of acquiring the position information when shooting the multimedia resource. The terminal acquires the position information when shooting the multimedia resource based on the acquisition authority of the position information, so that the shot multimedia resource carries the position information. The location information is also used to indicate the location of the terminal when the terminal photographs the multimedia resource. Wherein optionally the location information comprises coordinates formed on the basis of any one of the coordinate systems. The embodiment of the present application is described by taking the example that the location information includes the geographical coordinates composed of longitude and latitude, which is not limited.

In an alternative implementation, the server performs real-time detection of arrival behavior based on the point of interest information. The step of obtaining the multimedia resources uploaded by the user account based on the first interest point by the server comprises the steps of receiving a content release request sent by the terminal, wherein the content release request carries the user account, the first interest point and the multimedia resources, and taking the multimedia resources carried by the content release request as the multimedia resources uploaded by the user account based on the first interest point by the server.

In another alternative implementation, the server periodically performs detection of arrival behavior based on the point of interest information. The step of obtaining the multimedia resources uploaded by the user account based on the first interest point by the server comprises the step of obtaining the multimedia resources stored in association with the first interest point and the user account by the server in response to the arrival detection period. The detection period may be configured to be any time, for example, 1 hour, 1 day, or 3 days, which is not limited in the embodiment of the present application. It should be noted that, before the server obtains the multimedia resource stored in association with the first interest point and the user account, the server also stores the first interest point, the user account and the multimedia resource in association. The method comprises the steps that a server receives a content release request sent by a terminal, wherein the content release request carries a user account, the first interest point and the multimedia resource, and the server stores the user account, the first interest point and the multimedia resource carried by the content release request in an associated mode.

202. The server determines a plurality of second points of interest based on the first location information, a distance between the second points of interest and the first location information being less than a first distance threshold.

After the server acquires the first position information carried by the multimedia resource, a plurality of second interest points positioned near the first position information are screened out, namely, a plurality of second interest points with the distance between the second interest points and the first position information being smaller than a first distance threshold value are screened out. Wherein the first distance threshold may be flexibly configured, for example, the first distance threshold is 800 meters or 1 km, etc.

203. The server determines a reference point of interest from a plurality of second points of interest that matches the multimedia asset.

The reference interest point is matched with the multimedia resource, and the reference interest point is associated with the content displayed by the multimedia resource, that is, the reference interest point is most likely to be a shooting subject of the multimedia resource or a shooting subject which most likely includes the multimedia resource in the reference interest point, and the reference interest point is most likely to be an interest point actually expressed by the multimedia resource. The multimedia asset is captured by the user reaching a reference point of interest. The server determines a reference interest point matched with the multimedia resource through the identification of the multimedia resource and the comparison of the interest point information of the second interest points.

204. And the server responds to the fact that the first interest point is different from the reference interest point, and determines the user account as abnormal based on the arrival behavior of the first interest point.

If the first interest point on which the user uploads the multimedia resource is different from the reference interest point which is determined by the server and is actually expressed by the multimedia resource, the user is shown to be not reached to the first interest point to shoot and obtain the multimedia resource, and the user account is determined to be abnormal based on the arrival behavior of the first interest point. If the first interest point is the same as the reference interest point, the user reaches the first interest point to shoot, and the multimedia resource is obtained, optionally, the server does not process the arrival behavior of the user account based on the first interest point, or the server determines the arrival behavior of the user account based on the first interest point as normal, which is not limited in the embodiment of the application.

Fig. 3 is a flowchart of a method for detecting arrival behavior based on point of interest information according to an embodiment of the present application. Referring to fig. 3, this embodiment is illustrated by taking an interaction between a terminal and a server as an example, and includes:

301. The terminal acquires a multimedia resource to be published, and sends a content publishing request to the server, wherein the content publishing request carries a user account, a first interest point and the multimedia resource, and the multimedia resource carries first position information.

The terminal logs in with a user account. In an alternative implementation, the user uploads the multimedia resource in the content publishing interface of the first interest point, so that the terminal sends the multimedia resource to the server, and the server provides the multimedia resource to other users. The method comprises the steps that a terminal obtains a multimedia resource to be released and sends a content release request to a server, wherein the terminal responds to display operation of a content release interface of a first interest point and displays the content release interface of the first interest point, the terminal obtains the multimedia resource added based on the content release interface, and the terminal responds to detection of release operation implemented by a user on the content release interface and sends the content release request to the server, wherein the content release request carries the first interest point, the multimedia resource and a user account registered by the terminal.

In another alternative implementation, the user selects the first interest point in the process of publishing the multimedia resource, so that the terminal binds the multimedia resource and the first interest point. The method comprises the steps that a terminal obtains a multimedia resource to be released, and sends a content release request to a server, wherein the terminal responds to display operation of a content editing interface to display the content editing interface, the terminal obtains the multimedia resource added based on the content editing interface, responds to interactive operation of interest point options in the content editing interface to obtain a selected first interest point, responds to release operation carried out by a user on the content editing interface to send the content release request to the server, and the content release request carries the first interest point, the multimedia resource and a user account registered by the terminal.

Another point to be described is that the terminal supports the user to add multimedia resources. Optionally, the terminal supports the user in selecting the multimedia resource to be added from the stored multimedia resources. Wherein, optionally, the selected multimedia resource is shot based on the shooting function of the terminal, or the selected multimedia resource is transmitted to the terminal after shooting based on the shooting function of other terminals, which is not limited in the application. Optionally, the terminal also supports the user to shoot in real time based on the shooting function of the terminal, so as to obtain the multimedia resources to be added.

Another point to be described is that, in the process of capturing a multimedia resource, a terminal capturing the multimedia resource acquires the location information of the terminal in real time based on a location service, so that the captured multimedia resource carries the location information. The location information is used to indicate the location of the terminal, that is, the location when the multimedia resource is photographed.

It should be noted that, optionally, the terminal also supports the user to add text content, and the added text content is provided to other users simultaneously with the multimedia resource. Correspondingly, the terminal also acquires the input text content, and the text content is carried in a content release request sent to the server by the terminal.

302. The server receives a content release request of the terminal, and obtains multimedia resources uploaded by the user account based on the first interest point based on the content release request.

The server receives a content release request sent by a terminal, and obtains a user account, a first interest point and a multimedia resource carried by the content release request, so as to obtain the multimedia resource uploaded by the user account based on the first interest point.

It should be noted that, in the embodiment of the present application, the server receives the content distribution request of the terminal, acquires the multimedia resource carried by the content distribution request, and detects the arrival behavior in real time based on the multimedia resource. Optionally, in other embodiments, the server receives the content release request of the terminal, and performs the real-time detection of the arrival behavior based on the stored multimedia resource instead of the multimedia resource carried by the content release request, and stores the user account, the first interest point and the multimedia resource carried by the content release request in association with each other. Correspondingly, the step 302 can be replaced by the steps that the server receives a content release request of the terminal, performs associated storage on a user account, a first interest point and a multimedia resource carried by the content release request, and obtains the multimedia resource associated with the first interest point and the user account for storage in response to the arrival detection period, namely, the multimedia resource uploaded by the user account based on the first interest point.

303. The server determines a plurality of second interest points based on the first position information carried by the multimedia resource, wherein the distance between the second interest points and the first position information is smaller than a first distance threshold.

Each interest point corresponds to position information, and the position information is used for indicating the position of the interest point. The server determines the distance between the first position information and each interest point based on the first position information and the position information corresponding to the plurality of interest points, and determines the interest point with the distance smaller than a first distance threshold value with the first position information as a second interest point.

In an alternative implementation, the server determines a smaller area based on the first location information, and then screens out a plurality of second interest points near the first location information from a plurality of interest points in the area. Correspondingly, the step 303 comprises the steps that the server determines a target area comprising the first position information based on the first position information, and the server determines a plurality of second interest points with the distance between the second interest points and the first position information being smaller than a first distance threshold value from a plurality of interest points comprising the target area.

Optionally, the target area is an area centered on the first location information, and the target length is defined by a radius, where the target length may be flexibly configured to any length greater than or equal to the first distance threshold, for example, the target length is 2000 meters or 3000 meters, and so on. Or the target area is a more finely divided administrative area. For example, the target area is a three-level administrative district, i.e., a county-level administrative district, or more precisely, the target area is a four-level administrative district, i.e., a county-level administrative district.

According to the technical scheme, based on the first position information, the small target area containing few interest points is determined, and then the second interest points can be determined from the interest points contained in the target area through less distance calculation, so that compared with the calculation of the distance between a large number of interest points and the first position information, the time and calculation resources consumed by the distance calculation are reduced, the determination efficiency of the second interest points is improved, and the utilization rate of the calculation resources is improved.

304. The server determines a reference point of interest from the plurality of second points of interest that matches the multimedia asset.

In an alternative implementation manner, the server identifies a target interest point category corresponding to the multimedia resource, and determines a second interest point, which is the same as the target interest point category, of the corresponding interest point category as a reference interest point matched with the multimedia resource through comparison of the interest point categories. Accordingly, the above step 304 includes the following steps 30401 to 30402.

30401. The server identifies the multimedia resource to obtain a target interest point category corresponding to the multimedia resource, wherein the target interest point category is the category of the interest point shot by the multimedia resource.

Optionally, the server identifies the multimedia resource through a point of interest category identification model, and the point of interest category identification model is used for determining the category of the point of interest shot by the multimedia resource. The server inputs the multimedia resources into the interest point category identification model to obtain the target interest point category corresponding to the multimedia resources. Optionally, the server trains the multimedia resources marked with the interest point category as training samples to obtain an interest point category identification model.

30402. The server compares the interest point category corresponding to the target interest point category with the interest point categories corresponding to the plurality of second interest points respectively, and determines the second interest point, of which the corresponding interest point category is consistent with the target interest point category, as the reference interest point.

Wherein the points of interest correspond to the point of interest categories. The interest point category is a category to which an interest point belongs, and is a summary of interest point attributes in a category dimension.

In an alternative implementation, the point of interest category is the finest category to which the point of interest belongs, e.g., the point of interest category of "XX movie theatre" is movie theatre, the point of interest category of "XX museum" is Chinese lobby, and the point of interest category of "XX hotel" is hotel.

Optionally, the server compares the target interest point category with the interest point category corresponding to each second interest point, and determines the second interest point with the corresponding interest point category consistent with the target interest point category as the reference interest point according to the comparison results corresponding to the second interest points.

The server compares the target interest point category with the interest point category corresponding to a second interest point in the plurality of second interest points in sequence, determines the second interest point compared at this time as a reference interest point in response to the fact that the interest point category corresponding to the second interest point compared at this time is consistent with the target interest point category, ends the comparison process of the interest point category, and continues to acquire the interest point category corresponding to the next second interest point in response to the fact that the interest point category corresponding to the second interest point compared at this time is inconsistent with the target interest point category and compares the interest point category with the target interest point category. Optionally, the server sequentially acquires the interest point category corresponding to the second interest point according to the sequence from the smaller distance to the larger distance between the server and the first position information, and compares the interest point category with the target interest point category.

According to the technical scheme, the interest point category of the interest point shot by the multimedia resource is identified, the interest point category is compared with the interest point categories corresponding to the plurality of second interest points near the shooting position of the multimedia resource, and the second interest point which is the same as the interest point category corresponding to the multimedia resource is determined to be the reference interest point matched with the multimedia resource, so that the reference interest point can more accurately represent the interest point which is actually reached when the multimedia resource is shot, and further the accuracy of detecting the arrival behavior based on the interest point can be further improved based on the reference interest point with higher accuracy.

In another alternative implementation, the point of interest categories include categories of different hierarchies, including, for example, major, medium, and minor categories to which the point of interest belongs. For example, the interest point category of the XX chafing dish is food and beverage service, a middle dining room and a chafing dish shop, wherein the food and beverage service is a main category of the XX chafing dish, the Chinese dining room is a middle category of the XX chafing dish, and the chafing dish shop is a sub-category of the XX chafing dish.

Optionally, the server screens at least one second interest point which is the same as the major class in the target interest point class according to the major class in the target interest point class and the major class in the interest point class corresponding to the plurality of second interest points, screens at least one second interest point which is the same as the major class in the target interest point class according to the middle class in the target interest point class and the middle class in the interest point class corresponding to the screened at least one second interest point, screens at least one second interest point which is the same as the middle class in the target interest point class according to the major class and the second class in the interest point class corresponding to the screened at least one second interest point, and determines the reference interest point which is the same as the minor class in the target interest point class according to the minor class in the target interest point class and the minor class in the interest point class corresponding to the at least one second interest point which is the same as the middle class. If the number of the screened at least one second interest points is less than or equal to 1 in the process of determining the reference interest points, the subsequent screening process is not executed.

According to the technical scheme, the layer-by-layer screening is sequentially carried out based on the major class, the middle class and the minor class in the interest point class, so that the corresponding reference interest point with the interest point class consistent with the target interest point class is obtained.

In another optional implementation manner, the server identifies a category to which the shooting subject in the multimedia resource belongs, and determines a second interest point, which corresponds to the product category and is the same as the target product category, as a reference interest point matched with the multimedia resource through comparison of the product categories corresponding to the interest points, wherein the category is used as the target product category corresponding to the multimedia resource. Accordingly, the server determining a reference interest point matching the multimedia resource from the plurality of second interest points includes the following steps 30411 to 30112.

30411. The server identifies the multimedia resource to obtain a target product category corresponding to the multimedia resource, wherein the target product category is a category to which a shooting subject in the multimedia resource belongs.

Optionally, the server identifies the multimedia resource through a product category identification model, where the product category identification model is used to determine a category to which the subject in the multimedia resource belongs. And the server inputs the multimedia resource into a product category identification model to obtain the product category corresponding to the shooting subject in the multimedia resource. Optionally, the server trains the multimedia resource marked with the product category as a training sample to obtain a product category identification model.

30412. The server compares the target product category with at least one product category corresponding to the plurality of second interest points respectively, and determines the second interest points including the target product category in the corresponding at least one product category as reference interest points.

Wherein, a point of interest corresponds to at least one product category. The product categories are categories of products included within the point of interest, for example, at least one product category of "XX barbecue" includes crayfish, lamb shashlik, grilled squid, grilled chicken wings, poached peanuts, and the like. The server compares the target product category with at least one product category corresponding to each second interest point, and determines the second interest point as a reference interest point in response to the at least one product category corresponding to one of the second interest points including the target product category.

According to the technical scheme, the product category of the shooting subject in the multimedia resource is identified, the product category is compared with the product categories corresponding to the second interest points located near the shooting position of the multimedia resource, and the second interest points comprising the product category corresponding to the multimedia resource are determined to be the reference interest points matched with the multimedia resource. Through finer comparison in the product category dimension, the reference interest point can more accurately represent the interest point actually reached when the multimedia resource is shot, and further, the accuracy of detecting the arrival behavior based on the interest point can be further improved based on the reference interest point with higher accuracy.

In another alternative implementation, the server determines the reference point of interest that matches the multimedia asset based on a similarity between the multimedia asset and the reference multimedia asset corresponding to the second point of interest. The server determining a reference point of interest matching the multimedia asset from the plurality of second points of interest includes the following steps 30321 to 30422.

30421. The server determines reference similarity corresponding to the second interest points based on the multimedia resource and at least one reference multimedia resource corresponding to the second interest points.

Wherein the interest point corresponds to at least one reference multimedia resource. Optionally, the multimedia resource is referred to as an official multimedia resource uploaded by an operator of the interest point, or the multimedia resource is referred to as a multimedia resource included in the content marked with the quality label, wherein the content marked with the quality label is the content which is released by a user who reaches the interest point to experience and meets the quality judging condition.

The server determines at least one similarity corresponding to the second interest points based on the multimedia resource and at least one reference multimedia resource corresponding to the second interest points respectively, and determines the maximum similarity in the at least one similarity corresponding to the second interest points as the reference similarity corresponding to the second interest points respectively.

One point of interest may have a plurality of things that are indicative, and the subjects of shooting in a plurality of reference multimedia resources are different things. The shooting subject of the multimedia resource uploaded based on the first interest point may be one of things, so that the multimedia resource has higher similarity with the reference multimedia resource of which the shooting subject is the same thing, and has lower similarity with other reference multimedia resources. Therefore, the resource with the maximum similarity in at least one reference multimedia resource has higher reference value for determining the reference interest point, the maximum similarity is taken as the reference similarity to determine the reference interest point, and compared with the fact that the lower similarity generated by different shooting subjects is taken as the reference similarity to determine the reference interest point, the error determination of the reference interest point can be reduced, and the accuracy of determining the reference interest point is further improved.

Wherein, optionally, the server performs feature extraction on the multimedia resources, and determines the similarity between the multimedia resources based on the obtained feature vector. Correspondingly, the step of determining at least one similarity of the plurality of second interest points based on the multimedia resource and the at least one reference multimedia resource corresponding to the plurality of second interest points respectively comprises the steps of performing feature extraction on the multimedia resource by the server to obtain a first feature vector of the multimedia resource, performing feature extraction on the at least one reference multimedia resource corresponding to each second interest point by the server for each second interest point of the plurality of second interest points respectively to obtain at least one second feature vector of the at least one reference multimedia resource, and determining at least one similarity of the first feature vector and the at least one second feature vector respectively, wherein the at least one similarity is at least one similarity corresponding to each second interest point.

30422. And the server determines the corresponding second interest point with the reference similarity larger than the similarity threshold value as the reference interest point.

Alternatively, the similarity threshold may be flexibly configured to any value between 0 and 1. For example, the similarity threshold is 0.8, 0.85, or 0.9, which is not limited in this embodiment of the present application.

According to the technical scheme, the similarity between the multimedia resource uploaded based on the first interest point and the reference multimedia resource is determined, the interest point with the similarity larger than the threshold value is determined as the reference interest point, and the reference interest point is determined by focusing on the similarity between the contents of the multimedia resource, so that the reference interest point can more accurately represent the interest point actually reached when the multimedia resource is shot, and further, the accuracy of detecting the arrival behavior based on the interest point can be further improved based on the reference interest point with higher accuracy.

In another alternative implementation, text information exists in the multimedia resource uploaded by the user account, for example, the multimedia resource includes a sign of the point of interest, and the text information included on the sign is the name of the point of interest. Correspondingly, the step of determining the reference interest point matched with the multimedia resource by the server from the plurality of second interest points comprises the steps that the server extracts text information from the multimedia resource, the server compares the text information with names corresponding to the plurality of second interest points respectively, and the server determines the second interest point with the corresponding name in the text information as the reference interest point. The interest points are corresponding to names, for example, the name of a certain interest point is "XX museum".

According to the technical scheme, under the condition that text information exists in the multimedia resource, the text information included in the multimedia resource is identified, and if the identified text information includes the name of a certain interest point, the interest point is determined to be a reference interest point. Because the names of the interest points are usually unique, the reference interest points are determined based on the names of the interest points, the determined reference interest points can more accurately represent the interest points actually reached when the multimedia resource is shot, and further the accuracy of detecting the arrival behaviors based on the interest points can be further improved based on the reference interest points with higher accuracy.

It should be noted that, alternatively, the server determines the reference interest point matching the multimedia resource from the plurality of second interest points based on any one of the above alternative implementations, or the server determines the reference interest point matching the multimedia resource from the plurality of second interest points based on a combination of any one of the above alternative implementations, which is not limited in this application.

305. And the server responds to the fact that the first interest point is different from the reference interest point, and determines that the user account number is abnormal based on the arrival behavior of the first interest point.

After determining the reference point of interest from the plurality of second point of interest through step 304, the server determines whether the first point of interest is the same as the reference point of interest. Optionally, the server determines whether the first point of interest is the same as the reference point of interest based on one or more aspects of a name, location information, a point of interest category, and a product category corresponding to the point of interest. For example, the server determines that the first interest point is the same as the reference interest point in response to the first interest point having the same name as the reference interest point and the position information corresponding to the first interest point is the same as the position information of the reference interest point, and determines that the first interest point is different from the reference interest point in response to the first interest point having a different name than the reference interest point or the position information corresponding to the first interest point is different from the position information of the reference interest point.

If the server determines that the first interest point is the same as the reference interest point, the arrival behavior of the user account based on the first interest point is not processed, or the arrival behavior of the user account based on the first interest point is determined to be normal.

According to the technical scheme, the position information carried by the multimedia resource cannot be changed, so that the real position of the user account when the multimedia resource is shot can be represented, the reference interest point which is actually reached when the multimedia resource is shot can be more accurately determined based on the position information carried by the multimedia resource and the multimedia resource, and further, under the condition that the reference interest point is inconsistent with the first interest point on which the user account uploads the multimedia resource, the arrival behavior of the user account based on the first interest point is determined to be abnormal, and the accuracy of detecting the arrival behavior based on the interest point is improved.

It should be noted that, optionally, after determining that the arrival behavior of the user account based on the first interest point is abnormal, the server marks the multimedia resource uploaded by the user account based on the first interest point as abnormal positioning, so as to indicate that the multimedia resource does not coincide with the first interest point, so that the content recommendation service can adjust the recommendation sequence of the multimedia resource backwards based on the abnormal positioning mark of the multimedia resource, and further, the multimedia resource which is not marked as abnormal positioning mark is preferentially displayed in the display interface corresponding to the interest point, and the multimedia resource marked as abnormal positioning is displayed or not displayed after the multimedia resource which is not marked as abnormal positioning. Based on the above process, the multimedia resources with reference significance, which have higher association degree with the interest point, are preferentially displayed in the display interface corresponding to the interest point, so that the experience of the user uploading the multimedia resources conforming to the interest point can be expressed, the rights and interests of the interest point can be ensured, and the user browsing the display interface can also quickly and effectively know the interest point.

Optionally, after determining that the arrival behavior of the user account based on the first interest point is abnormal, the server reduces a ranking parameter of the multimedia resource uploaded by the user account based on the first interest point, where the ranking parameter is used to indicate a priority of displaying the multimedia resource in a display interface corresponding to the first interest point, so that when other terminals display the display interface corresponding to the first interest point, according to the ranking parameter, the server obtains the ranking parameter corresponding to the first interest point from the server, and preferentially displays the multimedia resource with higher ranking parameter to the user, so that the user can preferentially browse the multimedia resource with higher association degree with the first interest point, and quickly and effectively understand the first interest point, thereby improving man-machine interaction efficiency.

Optionally, after determining that the arrival behavior of the user account based on the first interest point is abnormal, the server returns a prompt message to the terminal, so that the prompt message is displayed, and the prompt message is used for prompting that the uploaded multimedia resource does not coincide with the first interest point, so as to prompt the user to upload the multimedia resource coinciding with the first interest point again.

Optionally, after determining that the arrival behavior of the user account based on the first interest point is abnormal, the server does not store the multimedia resources uploaded by the user account based on the first interest point, so that other terminals can not acquire the multimedia resources from the server when displaying the display interface corresponding to the first interest point, and can not display the multimedia resources in the display interface corresponding to the first interest point, thereby improving the association degree of the multimedia resources displayed in the display interface corresponding to the first interest point and the first interest point, facilitating the user to browse the multimedia resources with higher association degree with the first interest point in the display interface corresponding to the first interest point, enabling the user to quickly and effectively understand the first interest point, and improving the man-machine interaction efficiency.

The other point to be described is that after the server determines that the first interest point is different from the reference interest point, the server further determines the distance between the first interest point and the reference interest point, and in response to the distance between the first interest point and the reference interest point being greater than a second distance threshold, reduces a ranking parameter of the multimedia resource, where the ranking parameter is used to indicate a priority of the multimedia resource displayed in a display interface corresponding to the first interest point, and in response to the distance between the first interest point and the reference interest point being less than or equal to a second distance threshold, does not process the ranking parameter of the multimedia resource. Wherein the second distance threshold may be configured to be any value less than or equal to the first distance threshold, e.g., 300 meters or 500 meters, etc.

According to the technical scheme, the server reduces the sorting parameters of the multimedia resources only when the distance between the first interest point and the reference interest point is larger than the second distance threshold. Under the condition that the first interest point is inconsistent with the reference interest point due to errors in positioning, the ordering parameters of the multimedia resources are not reduced, misoperation of reducing the ordering parameters of the multimedia resources is reduced by allowing positioning errors in a certain range, and accuracy of ordering the multimedia resources is improved.

Another point to be described is that after determining that the first point of interest is different from the reference point of interest, the server further generates positioning calibration information for indicating the accuracy of checking the positioning in response to the distance between the first point of interest and the reference point of interest being greater than the second distance threshold. Optionally, the server sends the positioning calibration information to a terminal corresponding to an operation and maintenance person of the positioning service, so that the positioning person of the positioning service checks the accuracy of the positioning service, and if the positioning of the positioning service is inaccurate, the accuracy of the positioning is calibrated. If the distance between the first interest point and the reference interest point is greater than the second distance threshold value due to inaccurate positioning service, the server determines that the arrival behavior based on the first interest point is normal.

In order to make the process of detecting the arrival behavior based on the interest point clearer, the following description will take the interest point as a store as an example, referring to fig. 4, the user uploads the multimedia resource under the interest point, that is, uploads the multimedia resource in the content publishing interface corresponding to the interest point; the server determines, through the step 303, a nearby interest point list according to the location information of the multimedia resource, where the interest point list includes a plurality of second interest points, determines, through the step 303, a reference interest point matching with the multimedia resource, that is, determines, through the identification of the multimedia resource, which interest point the multimedia resource most likely belongs to, the server determines whether the identified interest point is consistent with the initially bound interest point, where the identified interest point is the reference interest point in the embodiment, the initially bound interest point is the first interest point in the embodiment, determines that the user's current store-to-store behavior is abnormal, that is, determines, through the step 305, that the user account is abnormal based on the arrival behavior of the first interest point, if the store-to-store behavior is determined to be abnormal, the content quality of the multimedia resource is determined to be affected by the abnormality, if the identified interest point is the reference interest point in the embodiment, the initially bound interest point is the first interest point in the embodiment, determines that the user's current store-to-store behavior is abnormal, if the identified interest point is not consistent with the initially bound interest point, and if the identified interest point is not equal to the initially bound interest point, determines that the user's current store-to-store behavior is greater than 500m, and if the user's arrival behavior exceeds the first interest point is determined to be more than 500m accurately located by the initially if the user's point is determined to be located m, the current flow of detecting the arrival behavior based on the interest points is ended.

It should be noted that, if the multimedia resource uploaded by the user account based on the first interest point does not carry the location information, the server determines whether the first interest point matches the multimedia resource through a step similar to step 304. For example, the server identifies the multimedia resource to obtain a target interest point category corresponding to the multimedia resource, if the interest point category corresponding to the first interest point is inconsistent with the target interest point category, the first interest point is not matched with the multimedia resource, the server determines that the arrival behavior of the user account based on the first interest point is abnormal, if the interest point category corresponding to the first interest point is consistent with the target interest point category, the first interest point is matched with the multimedia resource, the server does not process the arrival behavior of the user account based on the first interest point, or determines that the arrival behavior of the user account based on the first interest point is normal. For another example, the server determines at least one similarity between the multimedia resource and at least one reference multimedia resource corresponding to the first interest point, determines the arrival behavior of the user account based on the first interest point as abnormal if the maximum similarity in the determined at least one similarity is less than or equal to a minimum similarity threshold, and does not process the arrival behavior of the user account based on the first interest point or determines the arrival behavior of the user account based on the first interest point as normal if the maximum similarity in the determined at least one similarity is greater than the minimum similarity threshold. Wherein the lowest similarity threshold may be configured to any value between 0 and 1, for example, the lowest similarity threshold is 0.7 or 0.8, etc.

According to the technical scheme, under the condition that the multimedia resource uploaded by the user account based on the first interest point does not carry the position information, the matching degree of the multimedia resource and the first interest point can be determined through the identification of the multimedia resource, so that when the matching degree of the multimedia resource and the first interest point is low, the arrival behavior of the user based on the first interest point is determined to be abnormal, and the accuracy of detecting the arrival behavior based on the interest point is improved.

Another point to be described is that the above embodiment is described taking as an example the detection of the arrival behavior by the server based on the point of interest information. Alternatively, the steps 302 to 305 are performed by the terminal, and the process of the terminal performing the steps 302 to 305 is the same as the process of the server performing the steps 302 to 305. It should be noted that, in step 302, the terminal may locally acquire the multimedia resources uploaded by the user account based on the first interest point, in step 303, because the storage space of the terminal is limited, a massive interest point and corresponding interest point information cannot be stored, optionally, the terminal sends an interest point information acquisition request to the server, where the interest point information acquisition request carries first location information to request the interest point information corresponding to the second interest points returned by the server, in step 304, the terminal determines a reference interest point matched with the multimedia resources from the second interest points based on the interest point information corresponding to the second interest points returned by the server, in step 305, optionally, if the terminal determines that the first interest point is different from the reference interest point, the multimedia resources are not sent to the server, and prompt information is displayed, where the prompt information is used to prompt the uploaded multimedia resources not to match the first interest point, so as to prompt the user to upload the multimedia resources matching the first interest point again.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein.
