The background application broadcasts. After each background application receives the message, it can judge whether it needs to process it by itself. If not, it can discard it. Otherwise, it can perform follow-up operations such as parsing.

Referring to FIG. 1, a flow chart of a method for providing video search results in a smart TV according to an embodiment of the present invention is shown. As shown in FIG. 1, the method may include the following steps:

S101: Each time the user clicks a search result in the video search result interface, record the category label of the clicked search result, and determine the user's preference for each category of video by counting the category labels of each record. level of interest information;

As mentioned above, smart TVs provide users with a large number of videos. In order to facilitate users to search the huge video database, the smart TV system can provide video search services and filter out matching video results through input keywords. In the method provided by the embodiment of the present invention, firstly, when the user clicks the search result in the video search result interface, the category label of the selected search result is recorded, and the category labels of each record are counted , to determine the user's degree of interest in each category of video.

When using the video retrieval function of the smart TV, the user can input keywords for searching videos, such as the title of a film and television drama, the name of an actor or director, etc. Then the smart TV system can search the video database according to the input keywords and return the search results. For individual users, the interests of each user are often different, and the points of interest of individual users, such as the types of videos that a user is interested in, can be analyzed through the user's behavior habits. Specifically, when a user searches for a video, the item selected from multiple search results may be considered as the user's interest. Therefore, category tags can be preset for each video in the video search results. When the user selects a certain video item in the search results, the type of the video can often be regarded as the type of video that the user is interested in. After counting the number of video types selected by the user during the search process, the degree of interest of the user in each video category can be determined according to the statistical data.

Specifically, in the category labels of the video records selected by the user in the search results, the number of occurrences of each category label and the total number of search results clicked by the user in the search results can be counted, that is, the total number of record entries of the user can be changed. , and then calculate the ratio of the number of occurrences of each category label to the total number of record entries, and determine the user's interest degree information for each category of video according to the calculated ratio. Thus, the user's degree of interest in each category of videos can be reflected in a ratio expressed as a percentage, for example, the user's degree of interest in a certain category is 70%.

S102: After receiving the search keywords input by the user, obtain the information about the degree of interest of the user in each category of videos;

The user’s degree of interest in each category of video in the smart TV video search application determined in the previous step is obtained by counting the user’s selection of a certain category of video when searching for videos in the past. It reflects the degree of interest of individual users in each video category. After a certain amount of statistics is carried out for a period of time, the information on the degree of interest in each category of videos can be more in line with the user's real interest preference. The information on the degree of interest in each category of video can be stored in the local storage device of the smart TV used by the user, such as smart TV hard disk, expansion card, etc., or uploaded to the user's corresponding personal storage in the cloud service platform in space. Next, when the user performs a search, the information about the degree of interest of the current user can be applied to the optimization of the video search results. After receiving the search keyword input by the user, information about the degree of interest of the user in each category of videos may be obtained.

It should be noted that if the user uses the search function of the smart TV for the first time, since no data statistics have been carried out, and there is no corresponding information on the degree of interest in each category of video, at this time, the video category statistics data of group users can be used. Sort the search results of a keyword for the current user. Because the video type interest information of group users can also reflect the interests of individual users to a certain extent. Specifically, according to the historical search records of other users, it is possible to obtain the number of clicks of the search results of each category when other users use the search keyword to search; Search results are sorted by category.

S103: After obtaining the video search results matching the search keywords, sort the search results according to the category tags of each search result and the user's interest degree information for each category of videos, and then display them.

After the user enters a keyword through the video search function, he can search in the video database according to the input keyword, and obtain the search result matching the search keyword. The search result matching the search keyword can include multiple Video information entry, each video in the entry corresponds to the category label of the video. When providing search results containing these video entries in the smart TV, it can be based on the category label of each search result and the user's interest in each category of video The information is displayed after sorting the search results. For example, if the keyword entered by the user is "car", firstly, the category label with the most hits by the user in the video search results in the past is obtained as "action" movie, so as to determine that the type of video that the user is most interested in is action movie. However, in the video database, "car" can be used as a keyword to retrieve many movies of various categories related to the keyword "car". , display the video information items containing the category tag "action" in the search results at the forefront of the searched program.

If the video category information that the user is interested in is not obtained, then according to the historical search records, obtain the number of clicks of the search results of each category when other users use the search keyword to search; at this time, the According to the number of clicks by other users, sort the search result items of each category in the current search result of the current user.

Through the aforementioned steps, more optimized video search results can be provided to the user in the search function of the smart TV, so that the user can quickly and accurately find the type of video they are interested in. In addition, when providing search results, in addition to referring to the type of current user's own interest, it can also be combined with the degree of interest of other users in various resources when searching for the same keyword to conduct video programs on smart TVs. When searching, further obtain search results that are more in line with user needs. After getting the video search results that match the search keywords, you can obtain the number of users who click to watch the search results of each category when other users use the search keywords to search, and then according to the user's interest in each category of videos Information and the number of users who click to view the search results of each category, and sort the search results of each category. Specifically, when sorting the search results of each category, the first basic value of each category can be determined according to the user's degree of interest in the videos of each category; The second basic value of the category; assign the first weight to the first basic value, and assign the second weight to the second basic value, wherein the first weight is greater than the second weight; according to the first basic value and the second basic value of each category , the first weight and the second weight, calculate the scores of each category respectively; sort the search results of each category according to the scores of each category.

In the specific application process, in order to reflect the current user's interest level information on various types of videos, and the interest type statistical data of other users as auxiliary reference, you can set a relatively high weight for the current user's own interested type and base value. For example, assume that the current user is interested in a genre with a base value of 1000 and a weight of 70%, and other users are interested in a genre with a base value of 1 and a weight of 30%. And assuming that the current user is interested in sports, when searching for a certain keyword, the score of the sports search result can be 1000×70%=700; when other users search for this keyword, 2000 people click If the results of the entertainment category are obtained, the score of the entertainment category is 1×30%×2000=600. It can be seen that the score of the sports category is higher than that of the entertainment category, so the sports category will be displayed prior to the entertainment category. And if other users search for this keyword, 3000 people click on the result of the history category, then the score of the history category is 1×30%×3000=900, it can be seen that the score of the history category is higher than that of the sports category, so History will take precedence over sports. Among them, the basic value and weight can be dynamically adjusted according to the total number of people online.
