Semantic Interoperability in Architectures for Semantic Web Services

A driving motivation for semantic web services is the holy grail of automated semantic interoperability. This means we must take seriously the need for architectures that support translation during the dynamic invocation of services. I will argue that this need is not met by simply introducing middle agents to translate messages between parties. 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 of the ontology used in the service’s public description of its interface, into corresponding terms from the client’s local ontology in order to formulate a proper request. I will describe recent progress in developing a model of the service invocation process that folds in translation. I will also describe how this and related issues are impacting an abstract architecture for semantic web services, our charter on the Architecture Committee of the Semantic Web Services Initiative (SWSI).
