Foundations of Fuzzy Logic and Semantic Web Languages

Chapman & Hall/CRC Studies in Informatics Series.

The book is a rigorous account of  the mathematical methods and tools about the Foundations of Representing Fuzzy Information and Reasoning with it within Semantic Web Languages. The development covers the three main streams of Semantic Web languages: namely, triple languages RDF & RDFS, Conceptual languages  OWL, OWL 2 and their Profiles (OWL EL, OWL QL and OWL RL), and rule-based languages such as SWRL and RIF
