The great development of Internet technologies and the emergence of the semantic web have led to the specification of architectures and tools to describe and to allow the “relevant” sharing of heterogeneous information sources. Shared data can be annotated and mapped to an agreed representation of their semantic using ontologies. Ontology is a representation of a domain of interest which is agreed by a community of people. The aim of the paper is to propose a user’s query expansion methodology in a heterogeneous cooperation of information systems. We propose a complete architecture called OWSCIS (Ontology and Web Services Cooperation of Information Sources) of cooperation of information systems based on the use of reference ontology and several local ontologies. This paper highlights the query expansion methodology in this architecture. The objective is to help and guide the user during the query process by analysing his query and using the usual behaviours of the users to predict his need.
