Knowledge-based multi-media database management system and its application to map information systems

A structure of a multimedia database management system that enables inferential retrieval and automatic construction is proposed. It consists of three parts, namely, a knowledge base at the top, a relational manager in the middle, and a media-oriented manager at the bottom. An automatic recognition and data input method for map figure data and an automatic database construction method and renewal capability are introduced. The effectiveness of these methods has been confirmed by applying them to a prototype map-based system for utility management.<
