Detailed Description
The invention provides a live channel sorting method and a live channel sorting device. In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a live channel sorting method according to an embodiment of the present invention is provided. The method comprises the following steps:
s100, collecting original data related to a live channel. The raw data includes viewing data related to viewing of the live channel and sales data related to purchasing of the live channel.
In the live shopping process, the live webcast platform generally provides a plurality of different live channels for the user to select, and the different live channels may have different shopping contents, such as live channels for providing bedding sales, live channels for providing car sales, and the like.
The network platform can push the different live channels to the user in a list (including live channel 1, live channel 2, etc.) manner as shown in fig. 2. Therefore, the sorting result of the live channels in the list or other presentation forms can guide the selection of the user or play a role in recommendation.
The popularity or revenue expectation of a live channel may be reflected by a number of different types of data for a particular live channel. For example, data reflecting the viewing situation of the live channel, sales data reflecting the shopping success situation of the commodities on the live channel, and the like. The original data can be easily or simply acquired through actual conditions by the live broadcast platform, and the specific data acquisition process is the conventional technology and is not described herein any more.
Specifically, step S100 specifically includes: the raw data is collected at predetermined time intervals. Considering that the actual viewing or sale condition of the user or the live channel is a real-time changing data, a proper time interval can be preset for collecting and recording the original data at the corresponding moment. The time interval may be specifically adjusted according to actual conditions, such as a live broadcast period of a live broadcast channel, a refresh frequency of sorting, and the like, and may be set to 10 minutes or 20 minutes, for example. Under the condition that the live broadcast period of the live broadcast channel is short, the time interval can be shortened, the sampling frequency and the refreshing frequency are improved to adapt to the live broadcast period, and therefore live broadcast channel sequencing matched with real-time change conditions is provided.
And S200, generating corresponding evaluation data according to the original data.
In the practical application process, the acquired raw data part can be directly used for evaluating the live channel, and some types of raw data need to be subjected to specific processing to generate evaluation data so as to further display the specific state of the live channel, so that the live channel can be better evaluated.
Specifically, the raw data may include: current number of viewers, cumulative number of purchases, cumulative number of viewers, and average length of viewing time. The current number of viewers refers to the number of viewers watching the live channel (e.g., live channel 1). The accumulated purchasing number refers to the total purchasing number of the live channel played to the current time. The cumulative number of viewers refers to the total number of viewers who broadcast the live channel to the current time (the same user does not repeat the continuous or intermittent watching process). The average viewing duration refers to the length of time that the user is viewing the live channel on average.
Correspondingly, the evaluation data may then include: average number of people watched, purchase coefficient, current number of people watched, and average watching duration. The average number of watching people can be obtained by calculating the current number of watching people, and the purchasing coefficient is determined by the accumulated number of purchasing people and the accumulated number of watching people.
In the evaluation data, the current number of people watching can reflect the audience rating of the channel, the average number of people watching mainly displays the change of the audience rating of the channel, and the average watching duration can embody the attraction degree of the channel to audiences; the shopping coefficient may display the sales proceeds (i.e., the profit expectations) for the goods promoted by the channel.
The score (or value) of the live channel is comprehensively considered through the data of the four aspects, and the audience can be guided to watch the channel which is attractive to the user and has better commodity popularization effect through the sequencing result.
And S300, calculating to obtain the score of the live channel according to the evaluation data.
As described above, ratings data may generally include a number of different types of data (e.g., four for average number of viewers, purchase factor, current number of viewers, and average length of viewing time as described above) for better scoring of live channels. Preferably, in the process of calculating the score, corresponding weight values can be set for different evaluation data according to actual conditions, so that the score of the live channel can be better realized, and the preference of a user can be reflected.
The score of the live channel obtained through the evaluation data can better reflect the income expectation brought by the live channel and the popularity of the live channel.
S400, sorting the live channels according to the scores of the live channels.
And S500, outputting the sequenced live broadcast channels to a television live broadcast platform.
After the score of the live channel is calculated, the live channels can be sorted in descending order according to the level of the score of the live channel, and output in a specific form (for example, a list form as shown in fig. 2) for presentation to the user.
In this way, the live channels with higher scores or higher values are ranked in the front, so that the users are guided and recommended to enter the live channels with higher ranks, and the live platform can obtain higher expected revenue values. In addition, the sequencing is a dynamically changed sequencing result, and the real-time change situation can be better adapted according to the continuous change of the newly acquired original data.
Fig. 3 shows an application example of the live channel sorting method according to the embodiment of the present invention. In the present example of application, user 10, television 20, and service providing platform 30 are included. The live channel sorting method is executed on the service providing platform 30, and outputs a result or collects original data through the television 20. The user 10 interacts with the television 20 to watch a particular live channel and shop on the television 20.
The service providing platform may be any suitable electronic computing platform with certain logical computing capability, such as a server or a cloud computing platform.
In the service providing platform execution process, firstly at a specific time tiCollecting the current number of people watching
