Abstract:
To enable the representation and reasoning for fuzzy ontologies with expressive fuzzy knowledge on the semantic web, a new fuzzy extension of description logics called vague ALC which is based on vague sets is presented.The definition of vague set is introduced and then the syntax and semantics of vague ALC are formally defined.The forms of axioms and assertions in the vague ALC knowledge bases are specified.Finally, the tableau algorithm is developed for the reasoning in the vague ALC.The vague ALC based on vague set uses two degrees of membership instead of a single membership degree in the fuzzy sets and is more accurate in representing the imprecision in the degrees of membership.The vague ALC has more expressive power than ALC and can represent fuzzy knowledge and perform reasoning tasks based on them.Therefore, the vague ALC can enable the representation and reasoning for fuzzy ontologies with expressive fuzzy knowledge on the semantic web.
