Abstract

An ontology consists of a set and definition of concepts that presents the characteristics of a given domain and relationship between the elements. This paper proposes a semiautomatic method to construct a domain ontology using the results of text analysis and applies it to a document retrieval system. An experiment domain used to construct an ontology was selected by the pharmacy field in which the types of ontology appeared in a document were analyzed. By using these results, a processing method of the terminologies, which are combined with some specific nouns of suffices, and uses the semantic relation to construct an ontology. In order to present usefulness for retrieving a document using the hierarchical relations in an ontology, this study compares a typical keyword based retrieval method with an ontology based retrieval method, which uses related information in an ontology for a related feedback. As a result, the latter shows the improvement of precision and recall.
