[Longevity science research retrieval system using the thesaurus specifically developed for the science].

Gerontology is a new field including various disciplines such as medicine, engineering science, social science etc, and is sometimes called as "longevity science". Because of the wide area of the field, it is important to show the scope of the science and the development of its thesaurus contributes to this end. We developed a relevant thesaurus based on the research funded by Longevity Science Promotion Organization, and using the thesaurus, we also developed a database and retrieval system of the gerontology research. This system can be accessed on the Internet.
