Description Logics are object-oriented representation formalisms capturing the most popular features of structured representation of knowledge. Among their several application domains, they have been applied in the context of the so-called logic-based approach to multimedia information retrieval. In this paper we present a four-valued fuzzy DL which, combining non-classical (relevance) four-valued semantics with a fuzzy semantics, allows both the treatment of the inherent notions of uncertainty and relevance in multimedia object content representation and retrieval, and to deal with possible inconsistencies which may arise among these representations.

Abstract
Description Logics are object-oriented representation formalisms capturing the most popular features of structured representation of knowledge. Among their several application domains, they have been applied in the context of the so-called logic-based approach to multimedia information retrieval. In this paper we present a four-valued fuzzy DL which, combining non-classical (relevance) four-valued semantics with a fuzzy semantics, allows both the treatment of the inherent notions of uncertainty and relevance in multimedia object content representation and retrieval, and to deal with possible inconsistencies which may arise among these representations.File | Dimensione | Formato | |
