Abstract

The invention provides an intelligent device and a theme construction method. The smart device includes a display and a processor. When the processor receives a search instruction input by a user, in response to the search instruction, executing concept extraction on the search text to obtain a candidate concept set; filtering the candidate concept set through a gradient enhancement classifier to obtain a general bracket concept, executing concept matching marking on the video title and the general bracket concept to obtain a marked concept entity pair, and constructing a topic hierarchical relationship library according to a topic category corresponding to the video title and the concept entity pair, and controlling the display to display the recommended entities under the theme and concept corresponding to the search text based on the theme hierarchical relationship library. Therefore, the intelligent equipment can carry out theme construction according to the content searched by the user and the video title, so that the intention of the user is understood, a result which better conforms to the expectation of the user is returned, and meanwhile, the retrieval relevance, the retrieval efficiency and the retrieval recall rate are improved.

Description

technical field [0001] The present application relates to the technical field of smart devices, and in particular, to a smart device and a method for constructing a theme. Background technique [0002] Smart devices refer to terminal devices that can output specific display images, such as smart TVs, mobile terminals, smart advertising screens, and projectors. With the rapid development of smart devices, the functions of smart devices will become more and more abundant, and the performance will become more and more powerful. Diversity and individual needs. [0003] When a user uses a smart device to search for video content, in order to ensure that the video content that meets the user's interests is returned, currently, video retrieval is divided into two aspects. First, in terms of vision, the retrieval system establishes a feature library based on the underlying visual information of the video data, divides each frame of video data into shots in a certain way, then extr...
