【 摘 要 】

A fuzzy-logic based search engine for a soybean shape database was developed on the WWW.It used to be difficult to evaluate crop shape characteristics quantitatively.Image analyzing technologies, however, can now bring us several numerical parameters to describe crop shape and we can develop database systems of such numerical shape characteristics combining some image data.To make a search on shape information in such a database, one would rather prefer using naturally linguistic keywords such as"very fat and round"than numerical keywords because it is usually difficult to imagine appropriate values for what one wants in terms of shape.Therefore, a search system based on fuzzy logic with naturally linguistic and comparative keywords for shape information was developed in this study.In the fuzzy-logic based search system, a wide range of human subjectivity to the search results, caused mainly by the subjective recognition of each fuzzy keyword, can be distinct.Therefore, in order to adjust the system to such subjectivity, we prepared several search options;that is, two types of membership functions, flexible fuzzy range and three types of definitions on fuzzy membership logical products.One can try the system at http://zoushoku.narc.affrc.go.jp/snino/soyshape/search2.html.
