Abstract

Managing video data and providing semantic-based retrieval mechanism is an indispensable part of digital library. However, most exiting digital library systems only provide the functionality of retrieving video data by meta-data which can not fulfill users' requirements. This is due to the lack of appropriate video semantic model and powerful query interface. In this paper, we will first briefly introduce our video semantic model SemTTE and its query language VSQL, then show how they can be implemented based on XML technologies and how strategies of mapping and optimization are chosen.
