Knowledge Assisted Analysis and Categorization for Semantic Video Retrieval
In this paper we discuss the use of knowledge for the analysis and semantic retrieval of video. We follow a fuzzy relational approach to knowledge representation, based on which we define and extract the context of either a multimedia document or a user query. During indexing, the context of the document is utilized for the detection of objects and for automatic thematic categorization. During retrieval, the context of the query is used to clarify the exact meaning of the query terms and to meaningfully guide the process of query expansion and index matching. Indexing and retrieval tools have been implemented to demonstrate the proposed techniques and results are presented using video from audiovisual archives.
