Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when", "upon" or "in response to a determination" or "in response to a detection".
Furthermore, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.
Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather mean "one or more but not all embodiments" unless specifically stated otherwise.
First, the technical background of content recommendation is described. In the existing content recommendation method, candidate contents are generally sorted according to the content click rate to obtain a content queue; and then sequentially placing the candidate contents in the content queue at each showing position. For example: and obtaining 3 candidate contents A (the content click rate is 0.8), B (the content click rate is 0.9) and C (the content click rate is 0.3), and obtaining ase:Sub>A content sequence B-A-C according to the content click rate. Assuming 2 display positions, then B is placed in the first display position and a is placed in the second display position.
In practical applications, the content of a certain content type has a high "competitive" property because the click rate of the content is high. According to the existing content recommendation method, the content of the content type occupies most of the display positions in the sorting process, and the content of the content type with a low click rate may not be displayed. For example, a video will generally have a higher click through rate, which may result in the head recommendation bits being all video in the content queue obtained from the content click through rate.
In order to solve the above problem, an embodiment of the present application provides a content recommendation method. In the embodiment of the application, the display position is divided into position intervals, and the display intervals are distributed for different content types; then, each presentation interval is processed respectively, namely, each content type is subjected to competition according to the click rate in each presentation interval. By the method in the embodiment of the application, the situation that all content types compete for a certain display position at the same time is avoided, the competition is separated according to the position interval, the content of different content types can be displayed, and the situation that the content of a certain content type occupies all display positions is avoided.
The content recommendation method provided by the embodiment of the application can be executed by a processor of the target platform, and can also be executed by a processor of a content recommendation system for providing content recommendation service for the target platform. In an application scenario, a processor executing the content recommendation method provided by the embodiment of the application acquires respective corresponding position intervals of different content types on a target platform; then, ordering the first candidate content under the content type corresponding to each position interval according to the content click rate to obtain a first content sequence corresponding to the position interval; and then, according to the first content sequence corresponding to the position interval, determining the display content at each display position in the position interval, and displaying the display contents to the user through a foreground interface of the target platform.
The content recommendation method provided by the embodiment of the application is described below. Fig. 1 is a schematic flow chart of a content recommendation method provided in an embodiment of the present application. By way of example and not limitation, as shown in fig. 1, the content recommendation method may include the steps of:
s101, acquiring position intervals corresponding to different content types.
Wherein each position interval comprises at least one display position on the target platform. Each content type may correspond to one or more location intervals.
In addition, in order to determine the recommended content at each presentation position on the target platform, the sum of the ranges of the respective position intervals needs to cover all the presentation positions on the target platform. For example: the target platform has 20 display positions, and the position intervals are [1-5], [3-16] and [17-20] respectively. In this case, the sum of the ranges of the three location intervals may cover 20 presentation locations on the target platform.
The platform in the embodiment of the application refers to an information platform, such as a website and an application program, which can recommend content for a user and enable the user to search information by himself. The target platform refers to an information platform which needs to recommend content for a user. For example, a certain news website is an information platform, and when it is necessary to recommend content to a user on the news website by using the content recommendation method provided in the embodiment of the present application, the news website is a target platform in the embodiment of the present application.
In embodiments of the present application, the content type may include advertisements, albums, videos, cartoons, hotspots, and the like. May be the type of content that needs to be exposed on the target platform. Because the content provided by different target platforms is different, the content types can be divided according to actual needs, and are not specifically limited herein.
In one embodiment, the position interval may be obtained by the following steps:
assigning at least one content type to each presentation location on the target platform; and dividing the display positions of the distributed content types into a plurality of non-overlapping position intervals according to the content types and preset division rules respectively corresponding to each display position.
Optionally, the preset partition rule includes:
for any two adjacent display positions, if the content types corresponding to the two adjacent display positions are the same, dividing the two adjacent display positions into the same position interval.
And if the content types corresponding to the two adjacent display positions are different, dividing the two adjacent display positions into different position intervals.
For example, assume that the content types are albums, videos, and advertisements. Wherein, the content type distributed for the display positions 1-20 is an atlas, the content type distributed for the display positions 3-10 is a video, and the content type distributed for the display positions 7-12 is an advertisement. It can be seen that the display positions 1-2 can only display the atlas, 3-6 can display the atlas and the video (the content type corresponding to the display position 2 is different from the content type corresponding to the display position 3), 7-10 can display the atlas, the video and the advertisement (the content type corresponding to the display position 6 is different from the content type corresponding to the display position 7), 11-12 can display the advertisement and the atlas (the content type corresponding to the display position 10 is different from the content type corresponding to the display position 11), and 13-20 can display the atlas (the content type corresponding to the display position 12 is different from the content type corresponding to the display position 13). Then 1-20 display positions are divided into 5 non-overlapping position intervals of [1-2], [3-6], [7-10], [11-12], and [13-20] according to the content types respectively corresponding to the display positions and the preset division rule, and the sum of the ranges of the 5 position intervals can cover 20 display positions.
By the method, the disordered display positions can be ordered, so that each position interval and the content type form a clear mapping.
S102, sequencing the first candidate content under the content type corresponding to each position interval according to the content click rate, and obtaining a first content sequence corresponding to the position interval.
In the embodiment of the present application, the first candidate content in content type I refers to content that belongs to content type I and is not shown (i.e., is not assigned a showing position). When content recommendation is required according to the search keyword of the user, the first candidate content under the content type I refers to the content which is in line with the search keyword, belongs to the content type I and is not displayed. For example: the user inputs a search keyword "rabbit", the candidate content under the content type "atlas" is a picture containing or related to rabbits, and the candidate content under the content type "video" is a video containing or related to rabbits.
The processor executing the content recommendation method in the embodiment of the application acquires the first candidate content under the content type from the database corresponding to the target platform and sorts the first candidate content.
The database corresponding to the target platform can be a database of the target platform, can also be a third-party database such as a cloud storage space, and can also be a database of other information platforms performing data interaction with the target platform.
For the database of the target platform, when content is added to the database, each piece of added content needs to be subjected to security inspection, then a content tag is established for each piece of content, and finally the content and the content tag thereof are stored in the database. In this way, when executing step S102, the processor may determine the content in the database corresponding to the content tag matching the content type I as the first candidate content under the content type I.
The content click rate refers to the ratio of the number of times a piece of content on a web page is clicked to the number of times it is displayed. Reflecting the attention degree of a certain piece of content on the webpage.
Optionally, the first candidate content under the content type corresponding to each position interval may be sorted in the order from high to low in the content click rate.
As illustrated in the example of S101, one location interval may correspond to a plurality of content types. In this case, the first candidate contents of the plurality of content types corresponding to the position section are sorted together, and the first candidate contents corresponding to different content types "compete".
For example, assume that the content types corresponding to the location interval [3-6] are an atlas and a video, the first candidate contents under the atlas include a (content click rate is 0.3) and b (content click rate is 0.5), and the first candidate contents under the video include c (content click rate is 0.8), d (content click rate is 0.2), and e (content click rate is 0.6). Then the first content sequence corresponding to the position interval 3-6 is c-e-b-a-d.
S103, determining the display content at each display position in the position interval according to the first content sequence corresponding to the position interval.
When the first content sequence is obtained according to the content click-through rate from the large to the small, the content in the first content sequence may be sequentially assigned to the respective presentation positions in the order from the front to the back of the first content sequence.
In the embodiment of the present application, when the content x is assigned to the presentation position y, the content x is recorded as the presentation content at the presentation position y.
Continuing with the example in S102, the first content sequence corresponding to location interval [3-6] is c-e-b-a-d. Since there are 4 presentation positions in the position interval, which are 3, 4, 5, and 6, the first 4 pieces of content in the first content sequence are sequentially assigned to the 4 presentation positions. Specifically, c is assigned to 3, e is assigned to 4, b is assigned to 5, and a is assigned to 6. Wherein, the allocated 4 pieces of content c, e, b and a are the display content.
In the embodiment of the application, position intervals corresponding to different content types are obtained, which is equivalent to allocating a rough position range for each content type, so as to ensure that the contents of various content types can participate in sequencing; and then distributing content to each display position in each position interval according to the content click rate, so that the display positions are 'competed' among the first candidate contents according to the content click rate, and the displayed content is ensured to accord with the reading preference of a user. By the method, the content under each content type can be displayed on the premise of meeting the reading preference of the user, the situation that the content of a certain type occupies all display positions is avoided, and the reading experience of the user is improved.
In practical applications, since the click rate of a content of a certain content type is high, the "competitiveness" of the content type is strong, so that the content of the content type occupies most of the display positions in the sorting process, and the content of the content type with a low click rate may not be displayed.
In order to solve the above problem, in an embodiment, referring to fig. 2, a flowchart of a content recommendation method according to another embodiment of the present application is shown. By way of example and not limitation, as shown in fig. 2, the content recommendation method may further include the steps of:
s201, for any content type, obtaining the sequencing parameter of the content type.
The sorting parameters include a maximum exposure number and a minimum exposure number. The maximum exposure number is used to limit the maximum number of times that the content of each content type is allowed to be presented in one content recommendation process, i.e. at most several presentation positions can be occupied. The minimum exposure number is used to limit the minimum number of times that the content of each content type is allowed to be presented in one content recommendation process, i.e. the minimum number of presentation positions needs to be occupied.
S202, when the number of the vacant display positions corresponding to the content type is equal to the minimum exposure number in the sorting parameter of the content type, distributing the second candidate content under the content type to the vacant display positions corresponding to the content type according to the content click rate.
And S203, when the number of occupied display positions corresponding to the content type is equal to the maximum exposure number in the sequencing parameter of the content type, stopping distributing the display positions for the second candidate content under the content type.
The second candidate content under the content type I is the content which is not displayed in the first candidate content under the content type I when the number of the vacant display positions corresponding to the content type I is equal to the minimum exposure number corresponding to the content type I or when the number of the occupied display positions corresponding to the content type I is equal to the maximum exposure number corresponding to the content type I. For example: the first candidate content under content type I has a, b, c. When the number of the vacant display positions corresponding to the content type I is equal to the minimum exposure number corresponding to the content type I, or when the number of the occupied display positions corresponding to the content type I is equal to the maximum exposure number corresponding to the content type I, a is already allocated to the display position 1, namely a is already displayed, and b and c are not allocated, namely b and c are not displayed contents. So, the second candidate contents under content type I at this time are b and c.
The steps in S202 and S203 are explained below using an example.
Suppose that the display interval [1-2] can only display the atlas, the display interval [3-4] can display the video, and the display interval [5-6] can display the atlas and the video.
First, contents are assigned to the presentation positions in the presentation interval [1-2 ]. Assume that the first content sequence corresponding to the presentation interval [1-2] is a-b-c-d (i.e., a, b, c, and d are the first candidates under the atlas). Since there are only 2 display positions, i.e. a is assigned to display position 1 and b is assigned to display position 2. The remaining c and d are the second candidates in the atlas.
And then distributing the content to the display position in the display interval [3-4 ]. Assume that the first content sequence corresponding to the presentation interval [3-4] is e-f-g-h (i.e., a, b, c, and d are the first candidate content under the video). Since there are only 2 display positions, i.e. e to display position 3 and f to display position 4. And g and h are the second candidate content in the video.
And finally distributing the content to the display position in the display interval [5-6 ]. Suppose that the first content sequence corresponding to the presentation interval [5-6] is c-d-g-h, and the maximum exposure number 3 and the minimum exposure number of the atlas is 1, and the maximum exposure number of the video is 4 and the minimum exposure number is 1. The second candidate content c under the album is assigned to the presentation position 5 on the assumption described above. At this time, if there are 1, 2, 5, that is, 3 occupied display positions corresponding to the atlas, which is equal to the maximum exposure number of the atlas, the allocation of the display position for the second candidate content d under the atlas is stopped, so that the content d under the atlas is no longer allocated to the display position 6. At this time, the number of the vacant display positions (only 6) corresponding to the video is equal to 1, namely, the number of the vacant display positions is equal to the minimum exposure number of the video; therefore, the second candidate content g under the video is assigned to the presentation position 6 according to the content click-through rate.
In practical applications, in order to allocate the positions in order, the contents are usually allocated to the presentation positions in order from front to back.
By the method in the embodiment of the application, the contents of various content types can be effectively guaranteed to be displayed, and the distribution ordering of the display positions can be guaranteed.
In the solution described in the above embodiment, the location interval and the sorting parameter corresponding to each content type are fixed, and cannot be adjusted in real time according to the preference of the user.
In order to solve the above problem, in one embodiment, the content recommendation method may further include the steps of:
acquiring historical data corresponding to the t-th time period; determining a data volume ratio between different content types according to historical data; and adjusting respective sorting parameters of different content types in the t-th time period according to the data volume ratio and the preset floating number.
The history data includes content types to which the content of the operation performed by the user on the target platform before the t-th time period belongs. For example, the history data may include the content of the operation performed by the user in L time periods before the t-th time period and the content type thereof. The history data may also include H pieces of content that the user has operated most recently before the t-th time and the content type thereof. In other words, the history data may be acquired by time or by number.
The time period may be preset according to actual needs, for example, 1 time period may be 1 day, 1 hour, 1 week, 1 month, and the like. When a smaller time period is adopted, the adjustment frequency of the sequencing parameters is higher; otherwise, the adjustment frequency of the sequencing parameters is lower.
By changing the time period, the frequency of adjusting the sequencing parameters can be controlled, and the sequencing parameters can be flexibly adjusted according to actual needs, so that the content recommendation scheme in the application has stronger applicability.
The data volume ratio in the embodiment of the present application refers to a ratio of the number of times that a user performs an operation on content of different content types. Illustratively, the user clicks 3 pieces of content in L time periods before the t-th time period, wherein the content type of 2 pieces of content is video, and the content type of 1 piece of content is an atlas. Thus, the ratio of the amount of data for video to the atlas is 2:1.
Continuing with the above example, assuming that the preset floating number is 3, the maximum exposure number of the video is increased by 2 and the maximum exposure number of the atlas is increased by 1 according to the data amount ratio 2:1 of the video and the atlas.
For the content types not contained in the historical data, the sorting parameters can be kept unchanged, and the maximum exposure number can be correspondingly reduced according to the preset floating number.
By the method in the embodiment of the application, the sequencing parameters can be adjusted in real time, so that the sequencing result can follow the interest and preference of the user in real time.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
