De-duplication method for video material

Abstract

The invention relates to a video material deduplication method, which establishes an accurate range for subsequent processing by obtaining a script fragment and a semantic matched candidate video material fragment. The label matching degree is calculated based on the matching condition of the candidate video material segments and the scripts in the multi-level semantic label system, and it is ensured that the materials meet the script requirements in the subject and content categories. De-duplication related scores are calculated by analyzing the use history of candidate video material segments, the probability of repeatedly using the same or similar materials is effectively reduced through diversity scores, new materials are actively encouraged to be used through cold start scores, and the repetition risk and novelty of the materials are quantitatively evaluated from different dimensions. Finally, the target material is selected according to the tag matching degree and the weighting result of the deduplication correlation score, the content matching requirement and the deduplication target are organically combined, the repeated content is automatically avoided from the source in the material matching stage, a post-event manual auditing mode which is low in efficiency and high in subjectivity is replaced, and the intelligent level of video production is improved.
