Specifying Web Service Compositions on the Basis of Natural Language Requests

摘要

The introduction of the Semantic Web techniques in Service-oriented Architectures enables explicit representation and reasoning about semantically rich descriptions of service operations. Those techniques hold promise for the automated discovery, selection, composition and binding of services. This paper describes an approach to derive formal specifications of Web Service compositions on the basis of the interpretation of informal user requests expressed in (controlled) Natural Language. Our approach leverages the semantic and onto-logical description of a portfolio of known service operations (called Semantic Service Catalog).
