Abstract

Fuzzy temporal relations have been defined to support temporal knowledge representation and reasoning in the presence of fuzziness, which are still open issues. In this paper, we propose a generalized approach for determining fuzzy temporal relations assuming that fuzzy temporal intervals are all fuzzy. We firstly present the basics of representation of fuzzy temporal relations from two aspects: fuzzy time point and fuzzy time interval, and then give definitions of their fuzzy relations. On this basis, correspondences between fuzzy and crisp temporal relations are investigated. Finally, a general formalized algorithm for determining fuzzy temporal relations is proposed.
