Ontology Mapping for Dynamic Service Invocation on the Semantic Web

Mark Burstein

The need for translation during the dynamic invocation of services described on the semantic web is not addressed merely by introducing middle agents to translate messages. When an agent is attempting to utilize a service discovered and described on the Semantic Web using a service language like OWL-S, it must be able to translate descriptions of required inputs, given in terms from the ontology used in the service description, into corresponding terms from a local ontology in order to formulate a proper request. We are currently developing a model of the service invocation process that folds in translation. We are also addressing the issue raised here as we develop an abstract architecture for semantic web services, our charter on the Architecture Committee of the Semantic Web Services Initiative (SWSI).
