Service Discovery with Semantic Characteristics: ACTAS

Discovery is the task of locating (Web) Services by means of their semantic annotation. Semantic Web Services (SWS) annotate semantic information about their functionality through capability descriptions (e.g. WSMO, OWL-S). Many approaches of automatic discovery and composition of business services take advantage from SWS. However, discovery and composition of general services or discovery based on other service aspects as functionality are neglected. The paper introduces models of a Discovery Framework called ACTAS (Adaptive Composition and Trading based on Agents), which allows the matching through semantic characteristics and algorithms. Semantic service characteristics, published through an ontological repository, wrap service property objects and constraints. The description of services with the SWS interface needs rather an expert (e.g. in description logic (DL)). Semantic Service Characteristics can offer interfaces adapted for a definite user groups or domains. They allow the keeping of domain specific ontologies.
