Rich information is scattered under Indonesian Choral Lovers (ICL) mailing list and many of its members prefer posting a query-mail to using the available search engine. A text retrieval system based on ontology is then proposed. However, considering the continual number of emails, developing an automatic ontology constructor (OC) will be the focus of the study while the retrieval system becomes an evaluation tool of the OC developed. Besides using 3,000 emails of ICL as the corpus, this study is challenging for it takes a cognitive approach as the heart of the process and employs Linear Model known in Expert System field as the system life cycle. The effectiveness of OC will be determined based on the automatic-thesaurus effectiveness. Performance measure of information retrieval is going to be computed in technical evaluation while qualitative measures of ontology (consistency, completeness, and conciseness) are going to be used in user’s evaluation.
