Step 201 , sort the categories in the category table according to the recent access time and the number of visits of the categories in the pre-created category table by the user to generate a candidate category sequence.

In this embodiment, the above-mentioned pre-created category table includes the most recent visit time and the number of visits of the category, wherein the above-mentioned user is a designated user, such as a user using the terminal device, or a user corresponding to a designated user ID ; The most recent visit time is the last time the user visited the product content under this category; the number of visits is obtained by statistics, which can be the number of times the user has accessed the product content under this category within a set period of time. The duration is the time period from the current moment set according to the actual application scenario, for example, one month, one week, 60 days, etc., which is not specifically limited here. The executive body may sort the categories in the above category table according to the user's recent access time and the number of visits to generate a candidate category sequence. Specifically, the execution subjects may be sorted according to the size of the number of accesses, or may be sorted according to the order of the most recent access time, or may be sorted according to other specified sorting methods, which are not specifically limited here.

The number of visits The number of visits The number of visits The number of visits The number of visits Optionally, the above method for presenting category information is applied to the client, which can overcome the disadvantage that the sorting information of the categories is not real-time and accurate due to the limited collection of user information by the server, It can avoid leakage of user privacy, so that more information of users (such as browsing records and shopping records) can be obtained, and these information can be obtained in real time on the client side, which solves a series of problems such as traffic, privacy, and especially data effectiveness. .

Optionally, the above-mentioned pre-created category table is obtained through the following creation steps: first, a category table is created, and each piece of data in the category table includes category identification, number of visits, and recent access time; then, the execution body Determine the category identifier of the category to which the item information accessed by the user belongs, and in response to determining that there is a category identifier of the category to which the item information accessed by the user belongs in the category table, classifying the category of the item information accessed by the user in the category table into a category The number of visits corresponding to the target category identifier is increased by one, and the most recent access time corresponding to the category identifier of the category to which the item information accessed by the user in the category table belongs is updated to the time when the user accesses the item information.

The above category identifier may be preset information for identifying categories, such as a character string composed of numbers, letters, etc., or a text identifier, and may also be identification information in other formats such as pictures. . The above-mentioned item information may refer to item information involved in the web content browsed by the user, such as the title, picture, video, etc. of the item in a shopping application. The execution subject of the above-mentioned creation of the category table can be the client or the server. The client can create a category table by creating an empty table including fields such as category identification, number of visits, and recent access time, and then according to the user. Add content to the category table by the access records of Set the initial value of the number of times and the most recent access time, such as 0, and then send the category table created by the server to the client for the client to use.

Optionally, the above-mentioned creating step may further include: in response to determining that the category identification of the category to which the item information accessed by the user does not exist in the category table, adding the category identification of the category to which the item information accessed by the user belongs. In the above category table, set the number of visits of the category ID of the category to which the item information accessed by the user belongs to 1, and set the latest access time corresponding to the category ID of the category to which the item information accessed by the user belongs to the above. The time when the user accesses the above-mentioned item information and stores the category table after the above-mentioned adding operation.

Optionally, the above-mentioned creating step may further include: zeroing the number of visits and the most recent visit time corresponding to the category identifier whose most recent access time is earlier than the preset time in the above-mentioned category table. The above preset time can be set according to the actual application scenario, for example, 60 days ago, 7 days ago, etc., which are not specifically limited here.

By creating a category table and maintaining the category table in the above manner, efficient management of category information can be achieved, and memory space occupied by category information can be reduced. When the above method is applied to the client, it can avoid that the client's local management category information occupies too much storage and computing resources and affects the data processing efficiency of the client.

Step 202: Adjust the ranking of the categories in the candidate category sequence according to the category recently accessed by the user.

In this embodiment, the recently accessed category usually refers to the last category accessed by the user at the current moment, and may also refer to the last category in the user's historically accessed categories. The executive body can adjust the ordering of the categories in the candidate category sequence in the following ways: first determine whether the user's most recently accessed category is in the candidate category sequence, and if it already exists, put the most recently accessed category in the above category table. Add one to the number of purpose visits, and update the last visit time of the recently visited category to the time when the user last accessed the recently visited category, and then re-sort the category table after the above operation, for example, according to the number of visits Sort by size or by time of most recent access.

Step 203: Present category information according to the adjusted category order.

In this embodiment, the execution body may present the category sequence adjusted in step 202 on the page. Optionally, the above method for presenting category information may be applied to the client. At this time, the execution body If it can be a client, it will be presented on the display page of the client according to the order of the adjusted categories.

Continue to refer to FIG. 3 , which is a schematic diagram of an application scenario of the method for presenting category information according to this embodiment. In the application scenario 300 in FIG. 3 , the client 301 accesses the categories in the pre-created category table 303 according to the latest access time and the number of visits by the user 302 "category a, 12:10, 3 times; category b , 11:8, 2 times; category c, 10:30, 4 times; category d, 10:13, 3 times; category e, 9:7, 5 times; category f, 8 10 points, 7 times; category g, 5:10 points, 3 times" to generate a candidate category sequence 304. Specifically, the client 301 visits the categories in descending order according to the categories in the above category table. Sorting, in which the categories with the same number of visits are sorted according to the most recent visit time; finally get the candidate category sequence 304 "category f, 8:10, 7 times; category e, 9:7, 5 times ;Category c, 10:30, 4 times; Category a, 12:10, 3 times; Category D, 10:13, 3 times; Category g, 5:10, 3 times; item b, 11:08, 2 times"; adjust the ranking of the categories in the candidate category sequence 304 according to the user's most recent access category 305 "category h, 13:18, 1 time", specifically , the above recently visited category 305 can be added to the first position in the above candidate category sequence 304 to obtain a category sequence 306 "Category h, 13:18, 1 time; category f, 8:10, 7 times ; Category e, 9:7, 5 times; Category c, 10:30, 4 times; Category a, 12:10, 3 times; Category D, 10:13, 3 times; Category g, 5:10, 3 times; Category b, 11:8, 2 times"; category information is presented 306 according to the adjusted category order.

The method for presenting category information provided by the embodiments of the present application. The client side sorts the categories and presents them according to the user's most recently visited categories, realizing the differentiated presentation of category information for different users. efficiency. .

Continuing to refer to FIG. 4 , it shows a flow 400 of one embodiment of a method for presenting category information according to the present application. The method for presenting category information includes the following steps:

Step 401 , according to the preset weight of recent access time and the weight of access times, weighted summation of the most recent access time and access times of the categories in the category table, to determine the ranking value of the categories in the category table.

In this embodiment, the weight of the most recent access time and the weight of the number of visits may be values set according to the subjective weighting method or the objective weighting method, which is not specifically limited here, and the above-mentioned subjective weighting method may be the Analytic Hierarchy Process (AHP) ), or the Delphi Method. The above objective weighting method may be principal component analysis method or variation coefficient method. Optionally, the executive body may traverse the categories in the category table, and add the product of the weight of the most recent access time and the recent access time and the product of the weight of the number of visits and the number of visits to obtain the ranking value of the categories in the category table. The execution subject determines the ranking value of the categories in the category table according to the weight of the most recent access time and the weight of the number of visits. According to the different weight settings of the number of visits, the influence of the number of visits in the category sorting can be determined. For example, if the weight of the above number of visits is set to be larger, the category with a larger ranking value can be determined as a category with more visits, and a higher number of visits indicates that the category is more popular, and then the category with a higher ranking value can be determined as a category with more visits. The size of the category determines the popularity of the category. According to the different weight settings of the recent access time, the influence of the recent access time in the category ranking can be determined. For example, if the weight of the recent access time is set to be larger, the category with a larger ranking value can be determined as a category with a late access time, and a late access time indicates that the category was accessed recently. , and then determine the recent popularity of the category by the size of the ranking value. For another example, if the weight of the recent access time and the weight of the number of visits are set closer to each other, the category with more recent visits can be obtained from the category with a larger ranking value. It is used for subsequent recommendations to users, for example, arranging the category in a higher position. In shopping applications, it helps to improve the efficiency of users accessing information of interest and improve the shopping experience of users.

Optionally, the execution body may also calculate the ranking value according to the following formula: y=count*w_count+time/a*w_time, where y represents the ranking value, count represents the number of visits, w_count represents the weight of the number of visits, and time represents the latest access time (time converted to Unix timestamp), w_time represents the weight of the most recent access time, = represents an equal sign, * represents a multiplication sign, + represents a plus sign, / represents a division sign, and a represents a constant, because the value of the Unix timestamp is relatively large, It is inconvenient to calculate, so divide the timestamp by a constant a. The specific value of this constant can be set and adjusted according to the actual scene, so that the calculation result can be optimized. Using the above method, calculate the ranking value of each category, and then sort these values, you can obtain the purpose of sorting and sorting by user popularity. The above number of visits and the most recent visit time can reflect the user popularity of the category.

Optionally, the above-mentioned method for presenting category information is applied to the client, which can overcome the disadvantage that the sorting information of the classification is not real-time and accurate due to the limited collection of user information by the server, and can avoid leakage of user privacy, so that it is possible to obtain Users have more information (such as browsing records, shopping records), and the client can obtain this information in real time, solving a series of problems such as traffic, privacy, and especially data effectiveness.

Optionally, the above-mentioned pre-created category table can be obtained through the following creation steps: create a category table, and each piece of data in the category table includes category identification, number of visits, and recent visit time; determine the belonging of the item information accessed by the user. The category identification of the category, in response to determining that there is a category identification of the category to which the item information accessed by the user belongs in the category table, the category identification of the category to which the item information accessed by the user in the category table belongs is corresponding to the category identification. The number of visits is increased by one, and the most recent visit time corresponding to the category identifier of the category to which the item information accessed by the user in the category table belongs is updated to the time when the user accesses the item information.

The above category identifiers can be set according to actual needs, such as numbers, letters and other characters, which are not specifically limited here. The above-mentioned item information may refer to item information involved in the web content browsed by the user, such as the title, picture, video, etc. of the item in a shopping application. The execution subject of the above-mentioned creation of the category table can be the client or the server. The client can create a category table by creating an empty table including fields such as category identification, number of visits, and recent access time, and then according to the user. Add content to the category table by the access records of Set the initial value of the number of times and the most recent access time, such as 0, and then send the category table created by the server to the client for the client to use.

Optionally, the above-mentioned creating step may further include: in response to determining that the category identification of the category to which the item information accessed by the user does not exist in the category table, adding the category identification of the category to which the item information accessed by the user belongs. In the above category table, set the number of visits of the category ID of the category to which the item information accessed by the user belongs to 1, and set the latest access time corresponding to the category ID of the category to which the item information accessed by the user belongs to the above. The time when the user accesses the above-mentioned item information and stores the category table after the above-mentioned adding operation.

Optionally, the above-mentioned creating step may further include: zeroing the number of visits and the most recent visit time corresponding to the category identifier whose most recent access time is earlier than the preset time in the above-mentioned category table. The above preset time can be set according to the actual application scenario, for example, 30 days ago, 10 days ago, etc., which are not specifically limited here.

Step 402 , sort the categories in the category table according to the sorting value in descending order, and select the categories preset before the sorting to generate a candidate category sequence.

In this embodiment, the execution subject may select the categories preset before sorting to generate the candidate category sequence, that is, select the first preset number of categories with larger sorting values as the candidate category sequence. The preset number can be set according to actual needs, for example, it can be set according to the size of the page displayed by the client.

Step 403: Adjust the ranking of the categories in the candidate category sequence according to the category recently accessed by the user.

In this embodiment, the recently accessed category usually refers to the last category accessed by the user at the current moment, and may also refer to the last category in the user's historically accessed categories. The executive body can adjust the ordering of the categories in the candidate category sequence in the following ways: first determine whether the user's most recently accessed category is in the candidate category sequence, and if it already exists, put the most recently accessed category in the above category table. Add one to the number of purpose visits, and update the last visit time of the recently visited category to the time when the user last accessed the recently visited category, and then re-sort the category table after the above operation, for example, according to the number of visits Sort by size or by time of most recent access.

Optionally, the above-mentioned adjusting the ranking of the categories in the above-mentioned candidate category sequence according to the above-mentioned user's most recently visited category may also include: firstly determining whether the user's most recently visited category is in the candidate category sequence, and if there is an existing category. , and adjust the user's recently visited category to the top of the candidate category sequence. The executive body adjusts the user's recently visited category to the top of the candidate category sequence. When the display page is displayed, the recently visited category is ranked first. Usually, the user's recently visited category has a high probability of being the category that the user is interested in recently. Therefore, the recently visited category ranks first, which can improve the user's visit experience and search efficiency.

Optionally, the above-mentioned adjusting the ranking of the categories in the above-mentioned candidate category sequence according to the above-mentioned user's recently visited categories may also include: in response to determining that the above-mentioned user's recently visited categories are not located in the above-mentioned candidate category sequence, adding The most recently visited category of the above-mentioned user is inserted into the first position of the above-mentioned candidate category sequence; in response to the length of the candidate category sequence after inserting the above-mentioned user's recently visited category at the first position exceeds the maximum length of the above-mentioned candidate category sequence, the first position will be The last category in the sequence of candidate categories after being inserted into the most recently accessed category of the above-mentioned user is deleted. The executive body inserts the user's recently visited category into the first position of the candidate category sequence. When the display page is displayed, the recently visited category is ranked first, and the user can see it more clearly, which is helpful for the user to click to view. Usually The user's recently visited category has a high probability that the user is interested in the category recently, so the recently visited category is ranked first, which can improve the user's visit experience and search efficiency.

The above-mentioned maximum length can be set according to the actual application scenario, for example, can be set according to the size of the page displayed by the client. Specifically, for example, if the maximum length is 8, there are at most 8 categories in the candidate category sequence. For example, if the maximum length is 8, there are at most 8 categories in the candidate category sequence. The execution subject of the above method can obtain the candidate category sequence within the set maximum length range. The above approach takes into account that if the data has been accessed recently, the probability of being accessed in the future is also higher. The above method uses the LRU (Least recently used, least recently used) algorithm to eliminate data according to the historical access records of the data. The data is eliminated 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 save data. As shown in Figure 5, a linked list structure that can store 8 category IDs (category IDs) is established. The specific processing steps are as follows: First, when the user accesses a new category When the information is used, the category ID needs to be inserted into the head of the linked list, but before that, it is necessary to first check whether the category ID already exists in the linked list; then, if the category ID already exists in the linked list, the The category ID is moved to the head of the linked list; if the linked list does not exist, the category ID is inserted into the head of the linked list; finally, when the linked list is full, the category ID at the end of the linked list is discarded. In this way, the category ID in the LRU's linked list is inserted before the sorting result calculated according to the user's popularity (ie the number of visits and the most recent visit time), and the calculation result considering both the user's popularity and the LRU algorithm is completed. The number of data stored in the linked list of the LRU (that is, the maximum length of the candidate category sequence in the above step 405 ) can also be adjusted according to the actual situation.

Step 404 , present category information according to the adjusted category order.

In this embodiment, the execution body may present the category sequence adjusted in step 403 on the page. Optionally, the above method for presenting category information may be applied to the client.
