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.
