With continued reference to FIG. 2, a flow 200 of one embodiment of a method for presenting category information in accordance with the present application is shown. The method for presenting category information comprises the following steps:

step 201, sorting the categories in the category list according to the latest access time and access times of the user to the categories in the pre-created category list, and generating a candidate category sequence.

In this embodiment, the pre-created category table includes the latest access time and the access times of the category, where the user is a specified user, for example, a user using the terminal device, or a user corresponding to a specified user ID; the latest access time is the time when the user has accessed the product content under the category for the latest time; the access times are obtained by statistics, and may be the times of accessing the product content of the category by the user within a set time period, where the set time period is a time period from the current time, set according to an actual application scenario, for example, one month, one week, 60 days, and the like, and is not limited herein. The execution subject may sort the categories in the category table according to the latest access time and access times of the user, and generate a candidate category sequence. Specifically, the execution subjects may be sorted according to the size of the access times, may also be sorted according to the order of the latest access time, and may also be sorted according to other specified sorting manners, which is not specifically limited herein.

Access times optionally, the method for presenting category information is applied to a client, can overcome the defect that sorted sequencing information is still not real-time and accurate enough due to limited user information collected by a server, can avoid the privacy disclosure of a user, can acquire more information (such as browsing records and shopping records) of the user, can acquire the information in real time at the client, and solves a series of problems of flow, privacy, particularly data effectiveness and the like.

Optionally, the pre-created category table is obtained through the following creation steps: firstly, creating a category table, wherein each piece of data in the category table comprises a category identifier, access times and latest access time; then, the executive body determines the category identification of the category to which the article information accessed by the user belongs, and in response to determining that the category identification of the category to which the article information accessed by the user belongs exists in the category table, adds one to the access frequency corresponding to the category identification of the category to which the article information accessed by the user belongs in the category table, and updates the latest access time corresponding to the category identification of the category to which the article information accessed by the user belongs in the category table to the time when the user accesses the article information.

The category identifier may be preset information for identifying the category, such as a character string composed of numbers, letters, or the like, or a character identifier, or may be identification information in other formats such as pictures. . The item information may refer to item information that the user browses to the web content, such as a title, a picture, a video, and the like of an item in a shopping application. The execution main body for creating the category list can be a client or a server, and the creating of the category list by the client can be realized by creating an empty list comprising fields such as category identification, access times, latest access time and the like and then adding content to the category list according to the access record of the user; the step of creating the category table by the server may be adding a plurality of pieces of data consisting of a plurality of preset common categories to the category table, setting an initial value, for example, 0, for the number of accesses and the latest access time in the category table, and then sending the category table created by the server to the client for the client to use.

Optionally, the creating step may further include: in response to determining that the category list does not have the category identification of the category to which the item information accessed by the user belongs, adding the category identification of the category to which the item information accessed by the user belongs to the category list, setting the access frequency of the category identification of the category to which the item information accessed by the user belongs to 1, setting the latest access time corresponding to the category identification of the category to which the item information accessed by the user belongs to the time for the user to access the item information, and storing the category list after the adding operation.

Optionally, the creating step may further include: and setting the access times and the latest access time corresponding to the category identification with the latest access time earlier than the preset time in the category list to zero. The preset time may be set according to an actual application scenario, for example, 60 days ago, 7 days ago, and the like, and is not limited herein.

By creating the category list and maintaining the category list in the above manner, the high-efficiency management of the category information can be realized, and the memory space occupied by the category information is reduced. When the method is applied to the client, the influence of excessive storage and calculation resources occupied by the local management category information of the client on the data processing efficiency of the client can be avoided.

Step 202, the order of the categories in the candidate category sequence is adjusted according to the most recently accessed category of the user.

In this embodiment, the latest access category generally refers to the last category accessed by the user at the current time, and may also refer to the last category in the user's history access categories. The execution agent may adjust the ordering of categories in the sequence of candidate categories by: firstly, determining whether the latest access category of the user is in the candidate category sequence, if so, adding one to the access times of the latest access category in the category list, updating the latest access time of the latest access category to the time when the user last accesses the latest access category, and then re-sorting the operated category list, for example, sorting according to the size of the access times or sorting according to the latest access time.

And step 203, presenting the category information according to the adjusted category sequence.

In this embodiment, the execution subject may present the category sequence adjusted in step 202 on a page, and optionally, the method for presenting the category information may be applied to a client, where the execution subject may be a client, and present the display page of the client according to the adjusted order of the categories.

With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for presenting category information according to the present embodiment. In the application scenario 300 of fig. 3, the client 301 accesses the category in the pre-created category table 303 according to the latest access time and access times "category a, 12 o ' clock, 10 o ' clock, 3 o ' clock of the user 302; category b, 11 points 8 points, 2 times; category c, 10 points 30 points, 4 times; category d, 10 points 13 points, 3 times; category e, 9 points 7 points, 5 times; category f, 8 points, 10 points, 7 times; sorting the categories g, 5 points, 10 points and 3 times' to generate a candidate category sequence 304, specifically, sorting the categories in the category table from large to small according to the access times of the categories in the category table by the client 301, wherein the categories with the same access times are sorted according to the latest access time; finally obtaining a candidate category sequence 304' category f, 8 points and 10 points, 7 times; category e, 9 points 7 points, 5 times; category c, 10 points 30 points, 4 times; category a, 12 points, 10 points, 3 times; category d, 10 points 13 points, 3 times; category g, 5 points, 10 points, 3 times; category b, 11 points 8 points, 2 times "; adjusting the sorting of the categories in the candidate category sequence 304 according to the latest access category 305 "category h, 13 points 18 points, 1 time" of the user, specifically, adding the latest access category 305 to the first position in the candidate category sequence 304 to obtain a category sequence 306 "category h, 13 points 18 points, 1 time; category f, 8 points, 10 points, 7 times; category e, 9 points 7 points, 5 times; category c, 10 points 30 points, 4 times; category a, 12 points, 10 points, 3 times; category d, 10 points 13 points, 3 times; category g, 5 points, 10 points, 3 times; category b, 11 points 8 points, 2 times "; the category information is presented in the adjusted category ordering 306.

The method for presenting the category information is provided by the embodiment of the application. The client displays the sorted categories according to the latest accessed categories of the user, so that the category information is displayed differently for different users, the order of displaying the categories is more in line with the requirements of the user, and the efficiency of displaying the category information is improved. .

With continued reference to FIG. 4, a flow 400 of one embodiment of a method for presenting category information in accordance with the present application is shown. The method for presenting category information comprises the following steps:

step 401, according to the preset latest access time weight and access frequency weight, performing weighted summation on the latest access time and access frequency of the categories in the category table, and determining the sorting value of the categories in the category table.

In this embodiment, the latest visit time weight and the visit number weight may be values set according to a subjective weighting Method or an objective weighting Method, and the subjective weighting Method may be an Analytic Hierarchy Process (AHP) or a Delphi Method (Delphi Method), which is not specifically limited herein. The objective weighting method may be a principal component analysis method or a coefficient of variation method. Alternatively, the execution subject may traverse the categories in the category table, and add the product of the latest access time weight and the latest access time to the product of the access time weight and the access time to obtain the ranking value of the categories in the category table. And the execution subject determines the sorting value of the categories in the category table according to the latest access time weight and the access times weight. According to different weight settings of the access times, the influence of the access times in the category sorting can be determined. For example, if the access frequency weight is set to be larger, the category with the larger ranking value may be determined as the category with the larger access frequency, and if the access frequency is larger, the popularity of the category is higher, and then the popularity of the category is determined according to the size of the ranking value. According to different weight settings of the recent access time, the influence of the recent access time in the category ordering can be determined. For example, if the weight of the latest access time is set to be larger, the category with the larger ranking value may be determined as the category with the later latest access time, and the later access time indicates that the category is accessed by the latest time, and further, the recent heat of the category is determined according to the size of the ranking value. For another example, if the latest access time weight and the access frequency weight are set closer to each other, the category with the higher recent access frequency can be obtained from the categories with the higher ranking value, and can be used for subsequent recommendation to the user as the category of potential interest of the user, for example, the category is ranked at a higher position. In shopping applications, the method and the device are beneficial to improving the efficiency of accessing information of interest by a user and improving the shopping experience of the user.

Optionally, the execution body may further calculate the ranking value according to the following formula: y is count w _ count + time/a w _ time, where y represents a ranking value, count represents the number of accesses, w _ count represents the weight of the number of accesses, time represents the latest access time (time converted into Unix timestamp), w _ time represents the weight of the latest access time, represents an equal sign, + represents a plus sign, + represents a divide sign,/represents a constant, a represents a constant, and since the value of a Unix timestamp is large, it is not easy to calculate, so that the timestamp is divided by a constant a, and the specific value of the constant can be set and adjusted according to the actual scene, so that the result of calculation can be optimized. By the method, the sorting value of each category is calculated, and then the values are sorted, so that the purpose of sorting by using the user heat can be obtained. The access times and the latest access time can represent the user popularity of the category.

Optionally, the method for presenting category information is applied to a client, and can overcome the defect that the server collects limited user information and sorted sequencing information of the categories is still not real-time and accurate enough, so that privacy of the user can be prevented from being disclosed, further more information (such as browsing records and shopping records) of the user can be acquired, and the information can be acquired in real time at the client, so that a series of problems of flow, privacy, particularly data effectiveness and the like are solved.

Optionally, the pre-created category table may be obtained through the following creation steps: creating a category table, wherein each piece of data in the category table comprises a category identification, access times and latest access time; determining a category identification of a category to which the article information accessed by the user belongs, in response to determining that the category identification of the category to which the article information accessed by the user belongs exists in the category table, adding one to the access times corresponding to the category identification of the category to which the article information accessed by the user belongs in the category table, and updating the latest access time corresponding to the category identification of the category to which the article information accessed by the user belongs in the category table to the time for the user to access the article information.

The category identifier may be set according to actual needs, such as characters like numbers and letters, and is not limited specifically herein. The item information may refer to item information that the user browses to the web content, such as a title, a picture, a video, and the like of an item in a shopping application. The execution main body for creating the category list can be a client or a server, and the creating of the category list by the client can be realized by creating an empty list comprising fields such as category identification, access times, latest access time and the like and then adding content to the category list according to the access record of the user; the step of creating the category table by the server may be adding a plurality of pieces of data consisting of a plurality of preset common categories to the category table, setting an initial value, for example, 0, for the number of accesses and the latest access time in the category table, and then sending the category table created by the server to the client for the client to use.

Optionally, the creating step may further include: and setting the access times and the latest access time corresponding to the category identification with the latest access time earlier than the preset time in the category list to zero. The preset time may be set according to an actual application scenario, for example, 30 days ago, 10 days ago, and the like, and is not limited specifically herein.

And step 402, sorting the categories in the category list according to the sorting values from large to small, and selecting the categories with preset bits before sorting to generate a candidate category sequence.

In this embodiment, the execution subject may select a category with a preset bit before the sorting to generate a candidate category sequence, that is, select a preset number of categories with a larger sorting value as the candidate category sequence. The preset number may be set according to actual needs, for example, may be set according to the size of the display page of the client.

Step 403, adjusting the order of the categories in the candidate category sequence according to the latest accessed category of the user.

Optionally, the adjusting the ordering of the categories in the candidate category sequence according to the recently accessed category of the user may further include: firstly, whether the latest access category of the user is in the candidate category sequence is determined, and if the latest access category of the user exists, the latest access category of the user is adjusted to the first position of the candidate category sequence. The execution main body adjusts the latest access category of the user to the first position of the candidate category sequence, when the display page is displayed, the latest access category is arranged at the first position, and the high probability of the latest access category of the user is the category which is most interested by the user, so that the latest access category is arranged at the first position, and the access experience and the searching efficiency of the user can be improved.

Optionally, the adjusting the ordering of the categories in the candidate category sequence according to the recently accessed category of the user may further include: in response to determining that the most recently accessed category of the user is not located in the candidate category sequence, inserting the most recently accessed category of the user into a top of the candidate category sequence; and deleting the category which is sequenced at the last position in the candidate category sequence after the latest access category of the user is inserted at the first position in response to the fact that the length of the candidate category sequence after the latest access category of the user is inserted at the first position exceeds the maximum length of the candidate category sequence. The execution main body inserts the latest access category of the user into the first position of the candidate category sequence, when the display page is displayed, the latest access category is arranged at the first position, the user can more obviously check the latest access category, the user can click to check the latest access category, and generally the most probability of the latest access category of the user is the category which is most interested by the user, so that the latest access category is arranged at the first position, and the access experience and the searching efficiency of the user can be improved.

The maximum length may be set according to an actual application scenario, for example, may be set according to a size of a display page of the client. Specifically, for example, if the maximum length is 8, the candidate category sequence has at most 8 categories. For example, if the maximum length is 8, then there are at most 8 categories in the candidate category sequence. The subject can obtain the candidate category sequence within the set maximum length range by the method. The above method takes into account that if data has been accessed recently, then the probability of future access is higher. The method uses an LRU (Least recently used) algorithm to eliminate data according to the historical access records of the data. And eliminating the data according to the historical access records of the data. The main idea of the algorithm is as follows:

The LRU algorithm generally uses a linked list to store data, as shown in fig. 5, to establish a linked list structure capable of storing 8 category IDs (category identifiers), and the specific processing steps are as follows: firstly, when a user accesses a new category information, the category ID needs to be inserted into the head of a linked list, but before the new category information is accessed, whether the category ID exists in the linked list is searched for firstly; then, if the category ID already exists in the linked list, the category ID is moved to the head of the linked list; if the linked list does not exist, inserting the category ID into the head of the linked list; and finally, when the linked list is full, discarding the category ID at the tail part of the linked list. In this way, the category IDs in the LRU linked list are inserted in front of the sorting result calculated according to the user popularity (i.e., the access times and the latest access time), completing the calculation result that considers both the user popularity and the LRU algorithm. The number of data stored in the linked list of the middle LRU (i.e. the maximum length of the candidate category sequence in step 405) may also be adjusted according to the actual situation.

And step 404, presenting the category information according to the adjusted category sequence.

In this embodiment, the execution main body may present the category sequence adjusted in step 403 on a page, and optionally, the method for presenting category information may be applied to a client, where the execution main body may be a client, and present the display page of the client according to the adjusted order of the categories.

With further reference to fig. 6, as an implementation of the method shown in the above-mentioned figures, the present application provides an embodiment of an apparatus for presenting category information, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 2, and the apparatus may be applied to various electronic devices in particular.
