Opis

This volume contains the proceedings of the Second InternationalConferenceon Web Reasoning and Rule Systems (RR2008), which was held on October 31 and November 1 in Karlsruhe, Germany. The International Conference on Web Reasoning and Rule Systems (RR) is the major forum for discussion and dissemination of new results on all topics concerning web reasoning and rule systems. RR2008 built on the success of the First International Conference on Web Reasoning and Rule Systems RR2007, which received enthusiastic support from the Web Rules community. In 2008, as documented by this proceedings volume, RR continued the excellence of the new series. The reasoning landscape features theoretical areas such as knowledge rep- sentation(KR)andalgorithms;designaspectsofrulemarkup;designofontology languages;engineeringofengines, translators, andothertools;e?ciencyconsid- ations and benchmarking; standardizatione?orts, such as the Rules Interchange Format activity at W3C; and applications. Of particular interest has been the useofrulestofacilitate ontologymodeling, andtherelationshipsandpossible- teractions between rules and ontology languages like RDF and OWL, as well as ontology reasoning related to RDF and OWL, or querying with SPARQL. We received 35 submissions, each of which was reviewed by at least 3 P- gram Committee members. The committee decided to accept 21 papers, among these12full papers,4shortpapersand5posterpresentations.Theprogramalso featured two invited talks, one by Michael Kifer on the standardization activity around RIF, and one by Boris Motik on the theoretical foundations underlying theintegrationofdescriptionlogicsandrules.ThetalkbyMichaelKiferwasalso broadcast as a joint keynote to the International RuleML Symposium on Rule Interchangeand Applications (RuleML2008), held in parallelin Orlando(USA).

This book constitutes the refereed proceedings of the Second International Conference on Web Reasoning and Rule Systems, RR 2008, held in Karlsruhe, Germany in October/November 2008.

The 12 revised full papers, 4 revised short papers presented together with 5 poster papers were carefully reviewed and selected from over 35 submissions. The papers address all current topics in Web reasoning and rule systems such as acquisition of rules and ontologies by knowledge extraction, design and analysis of reasoning languages, implemented tools and systems, standardization, ontology usability, ontology languages and their relationships, rules and ontologies, reasoning with uncertainty, reasoning with constraints, rule languages and systems, semantic Web services modeling and applications.
