Description

Display device and personalized recommendation reason generation method Technical Field The application relates to the technical field of display equipment, in particular to display equipment and a personalized recommendation reason generation method. Background Along with the high-speed development of technology, the multimedia content searching function can be more accurately matched with different actual demands of different users, so that the accurate recommendation of the multimedia content is realized. In the conventional technology, after searching according to a search term input by a user, a display device often displays a poster and a name of a searched multimedia content through a search result page, so that the user can select the multimedia content to be watched for playing. However, the user does not see the multimedia content much, and in the short process of browsing the search result, it is often difficult to determine whether the multimedia content meeting the actual demand of the user exists only through the poster and the name, for example, the user searches for a movie of a certain actor, but the movie of the actor is more, the user tends to choose to watch the movie of the actor in which the prize is obtained or the score is higher, in this case, even if the search result is displayed in a manner of being obtained overpraise and ranked higher in front, the user cannot know which is obtained overpraise or scored higher only through the poster and the name, so that the search result meeting the actual demand of the user may still be missed, resulting in lower conversion rate of the multimedia content search function. Disclosure of Invention The application provides a display device and a personalized recommendation reason generation method, which are used for solving the problem of low conversion rate of a multimedia content search function. In a first aspect, some embodiments provide a display device including a display and a controller. Wherein the display is configured to display a user interface, the audio output device is configured to output sound, the controller is configured to: Responding to a multimedia content searching operation triggered by a target user, and displaying a searching result page; Selecting target multimedia content in the process of searching the multimedia content by the target user aiming at the search result page; Acquiring personalized recommendation reasons of the target multimedia content, wherein the personalized recommendation reasons are generated based on user portrait data of the target user and media asset data of the target multimedia content; and controlling at least one of the display and the audio output device to display the personalized recommendation reason. The method has the technical effects that the display equipment responds to the multimedia content searching operation triggered by the target user, the search result page is displayed, the target multimedia content is selected in the process of searching the multimedia content aiming at the search result page by the target user, the personalized recommendation reason of the target multimedia content is obtained, at least one of the display and the audio output device is controlled, the personalized recommendation reason is displayed, and the personalized recommendation of the target multimedia content is realized through the display of the personalized recommendation reason. Further, the personalized recommendation reason is generated based on the user portrait data of the target user and the media asset data of the target multimedia content, so that the relevance between the media asset data and the user portrait data can be effectively captured, the part matched with the user portrait data is captured from the media asset data, the generated personalized recommendation reason is more in line with the user requirement and interest based on the part of the media asset data matched with the user portrait data, and more effective information is provided for the user selection search result, so that under the condition that the target multimedia content meets the user requirement and interest, the situation that the user misses the search result meeting the actual requirement due to the information deficiency can be effectively avoided, the probability that the user finds the multimedia content meeting the self requirement and interest through the multimedia content search function is increased, the conversion is facilitated, and the conversion rate of the multimedia content search function is improved. On the other hand, the efficiency of searching the multimedia content can be improved, and unnecessary operations such as searching operation and browsing and the like caused by the fact that a user cannot judge whether the search result meets the self requirement are reduced, so that the user satisfaction of the multimedia content searching function is improved. In a second aspect, some em
