The International Web Rule Symposium, RuleML, has evolved from an annual series of international workshops since 2002, international conferences in 2005 and 2006, and international symposia since 2007. In 2011 two instalments of the RuleML Symposium will take place. The first one, RuleML2011-Europe, will be held in conjunction with IJCAI 2011 (International Joint Conference on Artificial Intelligence) in Barcelona, Spain, in July. The second, RuleML2011-America, will be co-located with the Business Rules Forum 2011 to be held in early November in Fort Lauderdale, Florida, USA. The second instalment will include the RuleML Challenge Award that this year will be dedicate to Rules and Ontologies.
For RuleML-2011@IJCAI a selection of the best papers will be presented during a joint session with IJCAI, and the authors of such papers will be invited to submit a revised version of their papers for inclusion in the IJCAI proceedings.
