A New Approach To Semantic Matchmaking Using Description Logics

Abstract. An agent wishing to delegate some of its tasks to others needs to use the services of a match-making agent. The quality of the matchmaking process represents a key success factor in the effective-ness of the delegation process. As more services are exposing descriptions based on languages devel-oped in the framework of Semantic Web, there is no doubt that Descriptions Logics (DLs) on which Web Ontology Language (OWL-DL) is based will be playing a major role in this context. This work contributes to the field in three ways. First, the DL ALCN was used in a matchmaking process that yields a justified ranking of results. Second, the matchmaking process provides useful information to the requester/provider in order to modify or refine the original request/capability description for a better result. Third, the requester agents should be able to further filter the results based on other criteria that we call “service goodness ” that are based on some Quality of Service (QoS) criteria as well as attributes such as trust and cost
