Thesaurus construction using class inheritance

Abstract

A lot of methodologies have been proposed for the component retrieval. Among them, thesaurus concept has been introduced for the similar component retrieval. In this paper, for the efficient retrieval of component, we classified classes with the concept of the inheritance relation and applied fuzzy logic to thesaurus method, and constructed an object-oriented thesaurus. The proposed method could express the category between concepts automatically, and calculate the fuzzy degree between classes by comparing matching weight with mismatching weight of each class and each category, and construct the thesaurus finally. By using classes of a component in the component retrieval, candidate components could be retrieved according to the priority order by the fuzzy similarity. Also, the retrieval performance was improved greatly by the thesaurus and the decision of the most suitable threshold value through simulation. © Springer-Verlag Berlin Heidelberg 2005.
