Recently in public enterprise companies, the demand for utilizing the multimedia database (MMDB) is rising. Such MMDB is used in the strategy information system (SIS) not only for special purposes such as facility management but also for the more general office sections. But there exists structural mismatch between user specified schema and a priori memolized schema of MMDB. Therefore, we express multimedia as object oriented structures and investigate analogical matching method of extracting the part of the structure that resembles the user specified scheme structure from this multimedia database. This new method is applied to an example that automatically summalize map for guidance from the residential map. As a result, we can get a prospect that an effective automatic summarization of map.
