Abstract

The invention discloses an end-to-end news program structuring method and a structuring framework system thereof, and relates to the technical field of news program processing, the method comprises the following steps: preprocessing an input news program to obtain audio resources and video resources of the news program; extracting basic information in the audio resource and the video resource by utilizing an ASR voice recognition technology, an OCR character recognition technology and a Shot Detection technology; based on the extracted basic information, extracting semantic theme information of each mode, carrying out fusion clustering on the semantic theme information of each mode by adopting a cross-mode theme fusion extraction algorithm, and outputting a Scene theme; meanwhile, carryingout cross-modal scene detection, and outputting a Scene level; performing scene aggregation and segmentation on the obtained Scene hierarchy and Scene theme by utilizing a CRF scene marking algorithm; and outputting the Story layer and the Scene layer with the same semantics. According to the method, the Story layer and the Story theme which have the same semantics are focused on, secondary utilization of the news programs is facilitated, and the use timeliness of the news programs is improved.

Description

technical field [0001] The present invention relates to the technical field of news program processing, and more specifically relates to an end-to-end news program structuring method and its structuring framework system. Background technique [0002] With the development of the times and the advancement of technology, video indexing and retrieval is an important issue and has great significance. And TV news is a large part of the video, and it is also a video that will be used repeatedly. For example, for on-demand broadcasting of TV news, it is necessary to segment the TV news stream, and then mark each segment of TV news stream with metadata, so as to quickly index and access; TV news programs are used as a material again, and used as The editorial materials of other news programs often reuse valuable fragments of news, and it is also necessary to decompose the TV news stream according to the structure of TV news and mark the valuable fragments. [0003] News video is an...
