Abstract
An extended fuzzy description logic is proposed to increase expressive power for complex fuzzy information. The extended fuzzy description logic introduces the cut sets of fuzzy concepts and fuzzy roles as atomic concepts and atomic roles, and inherits the concept constructors and knowledge base form of classical description logics to support a new logic system for knowledge representation. The definitions of syntax structure, semantic interpretation, knowledge base form and reasoning problems based on satisfiability are given for the extended fuzzy description logic. Comparing with the fuzzy description logic, it can be explained that fuzzy description logic can be converted into the extended fuzzy description logic, which extends the expressive power of the fuzzy description logic.
