Abstract: A hierarchical semantic associative video model was proposed which described video information in hierarchical concept tree,scene network and semantic object net. The concept tree could be constructed under different applications. Time information of video was represented by scene network. The contents of video shots were represented by semantic objects and their relations, and the semantic correlations between shots were represented by semantic relations among objects which were in different shots.Video can be retrieved by time information and other semantic information,and the results are convergented.

Key words: hierarchical semantic associative model, semantic network, video retrieval, content-based retrieval
