OWL-DL as a power tool to model negotiation mechanisms with incomplete information

. Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Korea, volume 4825 of LNCS, page 935--939. Berlin, Heidelberg, Springer Verlag, (November 2007)


We propose a framework to model negotiations among agents in scenarios withfully incomplete information. We address multi-issue bilateral negotiations, where issues are expressed and related to each other via an OWL ontology. In particular we use OWL DL sub-language - as it is the öfficial language" of the Semantic Web communities - and exploit its formal semantics based on the Description Logic SHOIN(D). Agents goals are expressed through OWL-DL as (complex) concept expressions, and the worth of goals as weights over concepts. We adopt a very general setting with incomplete information by letting agents keep both goals and worths of goals as private information. Moreover we propose a framework through which agents can negotiate and reach an agreement. Agents, according to the protocol, can pursue different sets of strategies, depending on their type.
