Inheritance Hierarchies in Fuzzy Object-Oriented Databases

In this paper, based on possibility distribution and the semantic measure of fuzzy data, we investigate subclasssuperclass relationships in the fuzzy object-oriented databases. We identify fuzzy class and develop soft computing methods in the paper to quantitatively determine the fuzzy subclasssuperclass hierarchies. The strategies to resolve the conflicts in multiple inheritance of class are also presented.
