Referring to fig. 4, a flowchart illustrating a first step of a first method for recommending information according to an embodiment of the present invention is shown, which may specifically include the following steps:
in the embodiment of the present invention, the mobile terminal runs with multiple application programs, the mobile terminal can receive an input instruction, the input instruction can include an initial search instruction, for example, a user inputs some keywords to search on an application program to obtain a search result, the search result can be recommendation information in a preset database in the application program, and it should be noted that the input instruction can also include a click instruction, that is, an instruction for the user to click and select a certain category in a home page of the application program to view.
Step 202, acquiring recommendation information from a preset database based on the input instruction; the recommendation information comprises a plurality of pieces of sub-recommendation information; the sub-recommendation information comprises a plurality of screening items respectively;
specifically, in the embodiment of the present invention, after the mobile terminal receives the input instruction, recommendation information is obtained from preset data according to the input instruction, such as "standard big bed room", "standard double bed room", "preferred double bed room" and the like shown in fig. 2, where the sub-recommendation information is information of the "standard big bed room", each sub-recommendation information includes a plurality of screening items, such as "free cancellation", "immediate confirmation" and the like in each sub-recommendation information in fig. 2, and the screening item is a label of the sub-recommendation information, that is, a user may search out sub-recommendation information meeting the requirement by specifying one or more screening items.
in practice, in the embodiment of the present invention, multiple candidate filter items in the filter items may be further determined, specifically, a click instruction of a user for the filter items may be received, and one or more candidate filter items may be determined through the click instruction, for example, after the user may click a "filter" button on fig. 2, the user may click a corresponding candidate filter item in a filter box displayed thereafter.
204, when any one of the sub-recommendation information does not simultaneously contain all candidate screening items, screening the sub-recommendation information according to the candidate screening items to obtain first specific sub-recommendation information and/or second specific sub-recommendation information;
the first specific sub-recommendation information is sub-recommendation information only containing one candidate screening item, and the candidate screening item is not contained in any other sub-recommendation information; the second specific sub-recommendation information is sub-recommendation information containing two or more candidate screening items, the candidate screening item of any one of the two or more candidate screening items is not simultaneously contained by all the rest sub-recommendation information, and the sub-recommendation information is not the first specific sub-recommendation information;
further, the mobile terminal may filter all sub-recommendation information according to the candidate screening options, if the number of the candidate screening options is N, the filtering result may be one or more sub-recommendation information including N candidate screening options, one or more sub-recommendation information including N-1 candidate screening options, one or more sub-recommendation information including N-3 candidate screening options, one or more sub-recommendation information including 2 candidate screening options, and one or more sub-recommendation information including 1 candidate screening option; because the result of recommending information does not necessarily satisfy all the conditions of the user, the user usually needs to repeatedly select the candidate screening items to obtain satisfactory recommending information.
In the embodiment of the invention, under the condition that any one piece of sub-recommendation information does not simultaneously contain all candidate screening items, the sub-recommendation information is screened according to the candidate screening items to obtain first specific sub-recommendation information and/or second specific sub-recommendation information; it should be noted that the first specific sub-recommendation information is sub-recommendation information that only includes one candidate screening item, and the candidate screening item is not included in any other sub-recommendation information;
the second specific sub-recommendation information is sub-recommendation information including two or more candidate screening items, a candidate screening item of any one of the two or more candidate screening items is not simultaneously included by all the rest of the sub-recommendation information, and the sub-recommendation information is not the first specific sub-recommendation information.
It should be noted that, in the embodiment of the present invention, the first specific sub-recommendation information may be screened first, and the second specific sub-recommendation information may be screened again in the case that the first specific sub-recommendation information does not exist; that is, the second specific sub recommendation information is filtered on the premise that the first specific sub recommendation information does not exist in the plurality of sub recommendation information.
in the embodiment of the invention, after the first specific sub-recommendation information and/or the second specific sub-recommendation information are/is obtained, the candidate screening items in the first specific sub-recommendation information are extracted; and when the number of the second specific sub-recommendation information is multiple, extracting candidate screening items in the multiple second specific sub-recommendation information, and finally determining the candidate screening items which are not simultaneously contained by the multiple second specific sub-recommendation information in the candidate screening items contained in the multiple second specific sub-recommendation information as target screening items.
And step 206, displaying the extracted target screening items.
In practical application to the embodiment of the present invention, the extracted target screening item may be displayed to provide for the user to delete, and when the user deletes the target screening item, the mobile terminal may match again in the preset database based on the deleted candidate screening item to obtain corresponding recommendation information, and display the recommendation information to the user.
In the embodiment of the invention, an input instruction is received; acquiring recommendation information from a preset database based on the input instruction; the recommendation information comprises a plurality of pieces of sub-recommendation information; the sub-recommendation information comprises a plurality of screening items respectively; determining a plurality of candidate ones of the screening items; when any one of the sub-recommendation information does not contain all candidate screening items at the same time, screening the sub-recommendation information according to the candidate screening items to obtain first specific sub-recommendation information and/or second specific sub-recommendation information; the first specific sub-recommendation information is sub-recommendation information only containing one candidate screening item, and the candidate screening item is not contained in any other sub-recommendation information; the second specific sub-recommendation information is sub-recommendation information containing two or more candidate screening items, the candidate screening item of any one of the two or more candidate screening items is not simultaneously contained by all the rest sub-recommendation information, and the sub-recommendation information is not the first specific sub-recommendation information; extracting target screening items in the first specific sub-recommendation information and/or the second specific sub-recommendation information; displaying the extracted target screening items; in the embodiment of the invention, the screening item causing no screening result is provided for the user, the user is advised to delete, the selection cost of the user is reduced, and the resources of the user are saved.
Referring to fig. 5, a flowchart illustrating a second step of the second method for recommending information according to the embodiment of the present invention is shown, which may specifically include the following steps:
in the embodiment of the invention, the mobile terminal can receive the search instruction, and the search instruction can comprise a keyword, for example, if the user inputs 'a certain hotel', the 'a certain hotel' is the keyword of the search instruction.
further, after the application program on the mobile terminal receives the keyword, the recommendation information matched with the keyword can be screened out from a preset database and displayed to the user. It should be noted that the recommendation information includes a plurality of sub-recommendation information; the sub-recommendation information respectively comprises a plurality of screening items.
in this embodiment of the present invention, the number of the candidate filter items is not specifically limited, and specifically, the candidate filter items may be determined by receiving a click command of the user for the filter item, that is, after the user clicks the filter item, the filter item is determined to be a candidate filter item.
304, when any one of the sub-recommendation information does not simultaneously contain all candidate screening items, matching the screening items in the sub-recommendation information according to the candidate screening items;
after determining the candidate screening items, screening the sub-recommendation information by using the candidate screening items, firstly, judging whether any sub-recommendation information simultaneously contains all the candidate screening items, when any sub-recommendation information simultaneously contains all the candidate screening items, at least one sub-recommendation information can meet the requirements of the user, and at the moment, displaying the sub-recommendation information meeting the requirements of the user to the user by the application program; however, when any one piece of sub-recommendation information does not simultaneously contain all the candidate screening items, that is, all the sub-recommendation information does not completely meet the requirements of the user, at this time, the screening items in the sub-recommendation information are matched according to the candidate screening items.
305, when any one screening item in the sub-recommendation information is matched with the candidate screening item and the candidate screening item is not contained in any other sub-recommendation information, determining that the sub-recommendation information is first specific sub-recommendation information;
further, the sub recommendation information may be classified according to the matching number of the filter item and the candidate filter item in the sub recommendation information, for example, if the number of the candidate filter items is N, the sub recommendation information may be divided into one or more sub recommendation information including N candidate filter items, one or more sub recommendation information including N-1 candidate filter items, one or more sub recommendation information including N-3 candidate filter items, one or more sub recommendation information including 2 candidate filter items, and one or more sub recommendation information including 1 candidate filter item.
In the embodiment of the present invention, sub-recommendation information in which any one of the filtering items matches the candidate filtering item is extracted as the first specific sub-recommendation information, that is, it is determined that the sub-recommendation information only including one of the candidate filtering items is the first specific sub-recommendation information, but the candidate filtering item in the first specific sub-recommendation information is not included in any other sub-recommendation information.
For example, referring to fig. 6, a schematic diagram of a screening relationship according to an embodiment of the present invention is shown; as shown in fig. 6, when the number of candidate screens is 2, each circle in the graph represents a number of sub-recommendation information having the same candidate screen, and three subgraphs from right to left represent three cases: "separate", "intersect", "coincide"; "separate" represents that there is no sub-recommendation information having two candidate screens at the same time, "intersect" represents that there is a part of sub-recommendation information having two candidate screens at the same time, and "coincide" represents that the sub-recommendation information of one candidate screen at least simultaneously contains another candidate screen;
while the case of the first specific sub-recommendation information may be a case of "split", assuming that 1 in fig. 4 is the candidate filter item "early", and 2 is the candidate filter item "free cancel"; if the candidate screening item 'early contained' is not included by other sub-recommendation information, it can be determined that the sub-recommendation information including the candidate screening item 'early contained' is the first specific sub-recommendation information, because the candidate screening item has the condition that the screening has no result, which is not beneficial to improving the decision efficiency of the user.
Step 306, when the sub recommendation information is not the first specific sub recommendation information and the sub recommendation information includes two or more candidate screening items, and the candidate screening item of any one of the two or more candidate screening items is not included by all the rest sub recommendation information at the same time, determining that the sub recommendation information is the second specific sub recommendation information;
in the embodiment of the invention, on the premise that the number of candidate screening items is N, when the sub-recommendation information is not the first specific sub-recommendation information, the sub-recommendation information containing 2 to N-1 candidate screening items is screened from the sub-recommendation information, and when any one of the 2 to N-1 candidate screening items is not simultaneously contained by all the rest sub-recommendation information, the sub-recommendation information is determined to be the second specific sub-recommendation information;
for example, referring to fig. 7, another screening relationship diagram of an embodiment of the invention is shown; as shown in fig. 7, each circle in the graph represents a plurality of sub-recommendation information with the same candidate filter item, and the plurality of sub-recommendation information are in a continuous "intersecting" condition, if 1 is "early" in the candidate filter item, 2 is "free cancel" in the candidate filter item, 3 is "self-run" in the candidate filter item, and 4 is "immediate confirmation" in the candidate filter item; as can be seen from the figure, some sub-recommendation information simultaneously contains candidate screening options of 'containing early (1)' and 'free cancellation (2)'; some sub-recommendation information simultaneously comprises candidate screening options of ' free cancellation (2) ' self-operation (3) '; some sub-recommendation information simultaneously comprises candidate screening options of ' self-operation (3) ' immediate confirmation (4) '; assuming that no other sub-recommendation information contains any one or more of the above candidate screens, i.e. neither "including early (1)", "free cancel (2)", or "self-run (3)", or "immediate confirmation (4)" (i.e. any one of the candidate screens) is simultaneously contained by all the other sub-recommendation information, the sub-recommendation information simultaneously containing the candidate screens "including early (1)", "free cancel (2)", the sub-recommendation information simultaneously containing the candidate screens "free cancel (2)", "self-run (3)", and the sub-recommendation information simultaneously containing the candidate screens "self-run (3)", and "immediate confirmation (4)" are determined as the second specific sub-recommendation information.
The above example is the case of two candidate screening items, and similarly, the method may be applied to the case of 2 to N-1 candidate screening items, and as long as the condition that any one candidate screening item of the 2 to N-1 candidate screening items is not simultaneously included by all the remaining sub-recommendation information is met, the sub-recommendation information is determined to be the second specific sub-recommendation information.
It should be noted that, when all the filter items are not matched with all the candidate filter items, the processing procedure is ended, and a prompt without a matching result is output to the user to prompt the user that there is no matching recommendation information under the candidate filter item selected by the user.
the method is specifically applied to the embodiment of the invention, after the first specific sub-recommendation information is acquired, the candidate screening items in the first specific sub-recommendation information are extracted, and the extracted candidate screening items are determined as the target screening items.
The core concept of the embodiment of the invention is that sub-recommendation information only containing one or two or more candidate screening items is screened, the corresponding candidate screening item is determined as a target screening item and provided for a user to delete, provided that the first specific sub-recommendation information is sub-recommendation information only containing one candidate screening item and the candidate screening item is not contained by any other sub-recommendation information, the second specific sub-recommendation information is sub-recommendation information containing two or more candidate screening items and the candidate screening item of any one of the two or more candidate screening items is not contained by all other sub-recommendation information at the same time, and the sub-recommendation information is not the first specific sub-recommendation information, otherwise, an effective screening result can be deleted by mistake.
Further, referring to fig. 8, another screening relation diagram according to the embodiment of the present invention is shown; as shown in fig. 8, when the number of candidate filter items is 3, each circle in the graph represents a number of sub-recommendation information with the same candidate filter item, and the filter relationship in the graph can be summarized as follows: the sub-recommendation information of one candidate screening item is considered to be separated when the sub-recommendation information of the candidate screening item is not intersected with the sub-recommendation information of the other two sub-recommendation information, and the three sub-recommendation information are considered to be overlapped when the three sub-recommendation information have common intersection; screening out sub-recommendation information only containing one candidate screening item or screening out sub-recommendation information containing two or more candidate screening items under the condition of non-coincidence (any one of the sub-recommendation information does not contain all the candidate screening items at the same time), but on the premise that the first specific sub-recommendation information is the sub-recommendation information only containing one candidate screening item and the candidate screening items are not contained in any other sub-recommendation information; the second specific sub-recommendation information is sub-recommendation information containing two or more candidate screening items, the candidate screening item of any one of the two or more candidate screening items is not simultaneously contained by all the rest sub-recommendation information, the sub-recommendation information is not the first specific sub-recommendation information, the corresponding candidate screening item is determined as the target screening item and is provided for the user to delete, and compared with a traditional selection mode, the decision efficiency of the user is greatly improved.
Step 309, when the number of the second specific sub-recommendation information is multiple, extracting candidate screening items in the multiple second specific sub-recommendation information;
