Abstract:

Aiming at automatic extraction of relationships between domain concepts in ontology construction, a hybrid automatic extraction method is proposed. The relationships existing in domain concepts are classified into two kinds: one is the relationships with unknown types extracted by the extended association rule; the other is the relationships with the known types extracted by extraction rules. Meanwhile, the formation and expansion methods of extraction rules are presented. Experiments demonstrate that the proposed method is feasible and effective. It can not only obtain rich relationships in special domain, but also obtain better performance.

Key words: hybrid extraction algorithm of relationships, extended association rule, extraction rule
