Aiming at distinguish objects, the concept of object comparison plays an important role in object management in object-oriented databases as well as object-oriented knowledge bases. In order to model uncertain data and complex-valued attributes as well as complex relationships among objects, fuzzy object-oriented databases have been introduced. In this paper, based on possibility distribution and the semantic measure of fuzzy data, we propose a more general way to compare fuzzy objects in the fuzzy object-oriented databases. We introduce an equivalence degree to compare fuzzy objects.
