Most of researches on content descriptions and queries of temporal features only base on the thirteen kinds of temporal relationships defined by Allen, which are difficult to answer the queries of multimedia data that are built on temporal semantic abstraction. Based on the definition of Multimedia Object and Multimedia Data Unit (MDU), this paper focuses on the descriptive algorithm of generalization and aggregation, which are two kinds of important temporal semantic abstraction.
