Web Reasoning and Rule Systems

This book constitutes the refereed proceedings of the First International Conference on Web Reasoning and Rule Systems, RR 2007, held in Innsbruck, Austria. It address all current topics in Web reasoning and rule systems, including acquisition of rules and ontologies by knowledge extraction, design and analysis of reasoning languages, reasoning with constraints, rule languages and systems, semantic Web services modeling and applications.
