16th Belgian-Dutch Conference on Artificial Intelligence (BNAIC2004) http://www.ai.rug.nl/conf/bnaic2004/ 21-22 October 2004 Groningen authors: Joost, Jacco Overall impression In general I found it an interesting experience, "gezellig" (cosy informal) might even be an appropriate term. There were a lot of familiar faces such as SEN representatives from CWI, a number of SIKS students, the semanticweb crowd from VU and some people I went to university with. The 'big guys' (frank, guus, bob etc) however were absent. The quality and the contents of the talk I found pretty good. This was mostly due to the fact that they allow already accepted papers for other conferences to be presented. This way you get a reasonable view of what is happening in other disciplines in AI. To conclude I think it will be good to show our face here one and a while and moreover a completely VU dominated semantic web track simply has to change. talks: Semantic Web track C-OWL: contextualizing ontologies This talk was presented at the iswc2004 in Florida. It talks about the difference between an ontology (=shared understanding of a domain) and a context (=model of a domain from 1 party). C-OWL is an extension of OWL which allows ontologies and context to live together. Foundations for Service Ontologies: Aligning OWL-S to DOLCE This talk was presented at WWW2004 and talked about the lack of semantics in OWL-S (ontology to describe web services). The authors tried to solve this by using an existing upper-ontology DOLCE to fill the semantic holes. They found this was a time intensive process due to incompatibility problems with the ontologies and the difficulty of really understanding the semantics of concepts in the upper layers of the ontology which are typically quite abstract. Methods for Porting Resources to the Semantic Web. This talk will be presented at iswc2005 and talked about a methodology for converting existing thesauri to the semantic web. Logic track Dialectical Argumentation with Argumentation Schemes: an approach to Legal Logic. This talk was about the "logical" reasoning in law cases which typically is less strict then in traditional logic. For example A saw that B murdered C -> B is guilty. However if you also know that A is unreliable then you cannot make this inference, unless there is evidence that A was reliable etc. The author presented a system which used argumentation schemes which can be used to analyze legal statements.
