| Outline of Final Research Achievements |
This study develops effective methods to prepare useful databases for datamining. It is in general not sufficient to use a database from a single source. We develop three types of methods that depend on different viewpoints. First, we assume a set of background knowledge is attached to the original database. Then a developed method automatically discovers useful data using the Web search, and attaches it to the database. Second, we develop a method to integrate multiple sources of databases into the one of a single source. The point here is to maintain many possibilities of the integration. Third, we develop an automatic acquisition of data with which we estimate the degree of reliability for the original database. These three types of methods and new datamining algorithms with them are implemented, and then the effectiveness is verified through experiments.
