Title: Ontology building by dictionary database mining Keywords: database mining, dictionary database, ontology, data mining Abstract: The paper examines the problem of building ontologies in automatic and semi-automatic way by means of mining a dictionary database. An overview of data mining tools and methods is presented. On this basis an extended and improved approach is proposed which involves operations for pre-processing the dictionary database, clustering and associating database entries for extracting hierarchical and nonhierarchical relations. The approach is applied on sample dictionary database in the environment of the Rapid Miner mining tool. As a result the dictionary database is complemented to thesaurus database which can be further on easily converted to reusable formal ontology. References Issue
