Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the technical scheme of the disclosure, the acquisition, storage, application and the like of the personal information of the related user all accord with the regulations of related laws and regulations, necessary security measures are taken, and the customs of the public order is not violated.
Under the live broadcast scene, the real-time online number of people in the live broadcast room can reflect the heat of live broadcast resources to a certain extent. If live broadcast resources with a large number of online people exist, the live broadcast resources can be considered to attract users to a certain extent and are high-quality live broadcast resources.
The inventor discovers that the real-time number of people in the live broadcast room is influenced by factors such as categories of live broadcast resources, the broadcasting time, the current broadcasting time and the like in the process of realizing the concept disclosed by the invention, and the deviation of the hot live broadcast is determined only according to the online number of people in the live broadcast room. For example, the number of people on line in jade and live broadcast rooms with goods resources is generally high. In addition, the hot of live broadcast is affected by the duration of the broadcast. For example, the number of live online people just started is small. Within a certain broadcasting time, the number of online people increases along with the increase of the broadcasting time.
Therefore, the deviation caused by factors such as the category of the live broadcast resources and the playing time is eliminated, and the live broadcast resources are pulled to the same dimension for comparison, which becomes the key point.

It should be noted that fig. 1 is only an example of a system architecture to which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, and does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios. For example, in another embodiment, an exemplary system architecture to which the live resource recommendation method and apparatus may be applied may include a terminal device, but the terminal device may implement the live resource recommendation method and apparatus provided in the embodiments of the present disclosure without interacting with a server.
As shown in fig. 1, the system architecture 100 according to this embodiment may include terminal devices 101, 102, 103, a network 104 and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105.

Fig. 2 schematically shows a flowchart of a live resource recommendation method according to an embodiment of the present disclosure.
As shown in fig. 2, the method includes operations S210 to S240.
In operation S210, a first ordering result for a plurality of first direct broadcast resources is obtained. The first sorting result is obtained by sorting the plurality of first direct-broadcast resources according to the first attribute information.
In operation S220, a weight value of each first direct broadcast resource is determined according to the first attribute value of the second attribute information of each first direct broadcast resource.
In operation S230, a second ranking result for the plurality of first direct broadcast resources is determined according to the weight value and the first ranking result.
In operation S240, a live resource to be recommended is determined according to the second sorting result.
According to an embodiment of the present disclosure, the first live resource may include various types of live resources that have been historically played and are being played. The first attribute information may include at least one of user attribute information such as user territory, category information of live broadcast resources, style and grade information of the anchor, and the like. The first ranking result is obtained by performing score evaluation and ranking on each live broadcast resource through a trained ranking model, for example. The ranking model is trained to perform score evaluation on each live broadcast resource based on first attribute information of each live broadcast resource, and rank the related live broadcast resources according to the score evaluation result.
According to an embodiment of the present disclosure, the second attribute information may be some or some of the first attribute information, or may be other attribute information different from any of the first attribute information. Taking a live broadcast resource as an example, the first attribute information includes, for example, a category of the live broadcast resource, an anchor style, an anchor level, a number of users who pay attention to the live broadcast, a number of users who have viewed the live broadcast, and the like, and the second attribute information may be at least one of a number of real-time users, a number of real-time comments, a user viewing duration, and the like in the live broadcast room, and is not limited herein.
According to an embodiment of the present disclosure, the weighting values may be a predetermined series of values, such as 1 to 10. Each weight value may represent a plurality of first attribute values within the same preset range. Taking the second attribute information as the number of real-time users in the live broadcast room as an example, the first attribute value can represent the number of the real-time users. When determining the weight value of the live broadcast room, for example, it may be determined that the weight value of the live broadcast room in which the number of users is less than 500 is 1, the weight value of the live broadcast room in which the number of users is in the range of 10 to 30 ten thousand is 5, and the weight value of the live broadcast room in which the number of users is greater than 100 ten thousand is 10. The weight value may also be a numerical value calculated from the first attribute value according to a preset function. For example, the preset function may be that the weight value = first attribute value/10000, and the weight value corresponding to a live broadcast room with the number of users being 500 is 0.05, and the weight value corresponding to a live broadcast room with the number of users being 10 ten thousand is 10.
According to the embodiment of the disclosure, the second sorting result is, for example, a result of re-sorting the first attribute values of the corresponding live broadcast resources after the weights of the first attribute values are adjusted according to the weight values of each live broadcast resource.
Through the above embodiment of the disclosure, as the first sorting result of the target live broadcast resource is readjusted by combining the second attribute information, the interest points hidden by the user can be mined, richer live broadcast resources can be recalled, and the live broadcast resources to be recommended are determined according to the adjusted second sorting result, so that the technical problem of poor single sorting recommendation effect is at least partially solved, and the user experience is improved.
The method shown in fig. 2 is further described with reference to fig. 3-4 in conjunction with specific embodiments.
Fig. 3 schematically shows a flow chart of a live resource recommendation method according to another embodiment of the present disclosure.
As shown in fig. 3, the method includes operations S310 to S360.
In operation S310, a first ordering result for a plurality of first direct broadcast resources is obtained. The first sorting result is obtained by sorting the plurality of first direct-broadcast resources according to the first attribute information.
In operation S320, feature information of each first direct broadcast resource is determined. The characteristic information comprises the live resource category of the first live resource and the live resource generation duration.
In operation S330, according to the live broadcast resource categories, a second attribute value of second attribute information of a second live broadcast resource is obtained for the feature information of each live broadcast resource category. And the second live broadcast resource is a live broadcast resource matched with the characteristic information.
In operation S340, in case that a preset condition is satisfied, a weight value of each first direct broadcast resource is determined according to a first attribute value and a second attribute value corresponding to the same feature information. The first attribute value is an attribute value of second attribute information of the first direct-broadcasting resource.
In operation S350, a second ranking result for the plurality of first direct broadcast resources is determined according to the weight value and the first ranking result.
In operation S360, a live resource to be recommended is determined according to the second sorting result.
According to the embodiment of the disclosure, the category of the live resources includes, for example, education, news, entertainment, games, goods, and the like, and the generation time of the live resources may be, for example, 30 minutes, 1 hour, 2 hours, and the like. Because the live broadcast resources of different categories have different heat degrees, and the heat degrees of the different live broadcast resources along with the change of the play duration may also be different, in order to eliminate the deviation caused by the category of the live broadcast resources and the play duration, for example, a dimension may be constructed according to the category of the live broadcast resources and the play duration, and the second live broadcast resource may be obtained based on the dimension.
According to the embodiment of the disclosure, a bucket can be constructed according to the feature information, and the second live broadcast resource and the second attribute value thereof acquired based on the feature information can be stored in the bucket. Taking the first live broadcast resource as the education live broadcast resource as an example, by analyzing the starting time of the education live broadcast resource, for example, determining that the characteristic information of the first live broadcast resource is the education live broadcast resource starting for 1 hour, a bucket for storing the education live broadcast resource starting for 1 hour and the second attribute value thereof can be constructed accordingly. In this case, the obtained second live broadcast resource is, for example, all educational live broadcast resources which are broadcast for 1 hour in history and are being broadcast. Taking the second attribute information as the number of real-time users in the live broadcast room as an example, the second attribute value can represent the number of current real-time users of the education live broadcast resources which are broadcast for 1 hour each time. The data stored in the bucket constructed with the educational type live resources that are played for 1 hour may include the current number of real-time users of the educational type live resources that are played for 1 hour each. The data in the bucket may be updated at the day level.
It should be noted that, a deviation threshold may be set for the live resource generation duration. For example, if the deviation threshold is set to 10 minutes, then 1 hour of playout could characterize the time period of 50 minutes of playout to 70 minutes of playout. By setting the deviation threshold, the fluctuation of the attribute value of the second attribute information, which may include the first attribute value and the second attribute value, can be further reduced. The deviation threshold value can be adaptively adjusted according to the actual scene.
According to the embodiment of the disclosure, the weight value of the first direct broadcast resource can be obtained by processing and calculating the first attribute value and the second attribute value through a predefined function.
Through the above embodiment of the present disclosure, a dimension can be established according to the live broadcast resource category and the live broadcast resource generation duration, and through analyzing the second attribute information of different live broadcast resources based on the dimension, the determined weight value of each live broadcast resource can eliminate the deviation caused by different factors such as the live broadcast resource category and the generation duration, and improve the validity of the live broadcast resource recommendation result.
According to an embodiment of the present disclosure, the characteristic information further includes time period information.
According to the embodiment of the disclosure, due to the fact that the popularity of different types of live broadcast resources in different time periods may be different, for example, the popularity of game type live broadcast resources is higher in the evening, and the popularity of news type live broadcast resources is higher in the morning. In order to eliminate the deviation caused by different time periods, for example, the time period information may be used as a reference dimension constituting the characteristic information. The time period information may be expressed as, for example, beijing time 7 to 9, 22.
According to the embodiment of the disclosure, corresponding to an actual first live broadcast resource, the characteristic information of the first live broadcast resource is, for example, a news-like live broadcast resource which is broadcast for 30 minutes in a time period of 7. A bucket may be constructed from the news-class live broadcast resources broadcast for 30 minutes in the time period from 7. The second attribute value may include attribute values of various types of second attribute information that are listed or not listed in the foregoing embodiment, which is not described herein again.
Through the embodiment of the disclosure, a dimension can be established according to the time period information, the category of the live broadcast resources and the generation duration of the live broadcast resources, the second attribute information of different live broadcast resources is analyzed based on the dimension, the weight value of each determined live broadcast resource can eliminate the deviation caused by different factors such as the time period, the category of the live broadcast resources and the generation duration, and the validity of the recommendation result of the live broadcast resources is further improved.
According to an embodiment of the present disclosure, the determining the weight value of each first direct broadcast resource according to the first attribute value and the second attribute value corresponding to the same feature information includes: and determining target characteristic information corresponding to the target first direct broadcasting resource. And acquiring a target second attribute value of the target second live broadcast resource matched with the target characteristic information. And determining a target attribute value corresponding to the target characteristic information according to the target second attribute value. And determining a weight value of the target first direct broadcast resource according to the target attribute value and the first attribute value.
According to the embodiment of the disclosure, the target feature information may include feature information constructed by a live resource category and a live resource generation duration, and may also include feature information constructed by time slot information, a live resource category and a live resource generation duration. The target attribute value may be determined by normalizing the target second attribute value for the respective second live resource. For example, the second attribute values of all live resources matched with the target feature information are stored in the bucket constructed by the target feature information, and the target attribute values can be determined by performing normalization calculation on the second attribute values of all live resources in the bucket. Based on the result of the normalization calculation, for example, a key-value pair having the target feature information as a key and the target attribute value as a value can be obtained, and the value of the second attribute information adapted to the target feature information can be characterized. For example, a specific value of the number of real-time users of a live resource of a predetermined category that is played for a predetermined period of time within a predetermined time period may be determined based on a key-value pair. The key-value pair may be stored in a dictionary or database for later recall for use.
Through the embodiment of the disclosure, a manner of determining the weight value of a single live broadcast resource is provided, and the weight value of the live broadcast resource is determined through the dimension defined based on the target characteristic information, so that each weight value can effectively represent the heat of one live broadcast resource in the defined dimension, and reliable data support is provided for subsequent efficient recommendation of the live broadcast resource.

The weighting process may use the weighting formula q _ ratio = factor described above. For example, q _ ratio4 adjust The result is obtained after weighting the evaluation value q _ ratio4 of G4 in the first ranking result. In the right-adjusting stage, for example, 200 live resources are reordered according to the right-adjusting result, and a result is shown as G4: q _ ratio4 adjust 、…、G1:q_ratio1 adjust 、G6:q_ratio6 adjust 、G2:q_ratio2 adjust 、G3:q_ratio3 adjust 、…、G5:q_ratio5 adjust 、G7:q_ratio7 adjust 、…、G200:q_ratio200 adjust ….
In operation S440, topN is taken. At this stage, the TopN (for example, top 5) pieces of the 200 live resources sorted by the second sorting result may be selected as the live resources to be recommended. At this stage, for example, topN (such as Top 50) pieces of the 200 live broadcast resources sorted according to the second sorting result may be selected for the second sorting and tuning, and then TopN (such as Top 5) pieces of the second sorting result after the second sorting and tuning are taken as the live broadcast resources to be recommended. It should be noted that the process of sorting and adjusting the right may be repeated multiple times to determine more accurate to recommend the live resources.
Through the embodiment of the disclosure, as the right-adjusting operation is further executed on the sequencing result, the interest points hidden by the user can be excavated, richer live broadcast resources can be recalled, and the user experience is improved.
