The eGovernment is a field of applications for the Semantic Web. The eGovernment also is becoming an important research area and faces considerable challenges to achieve interoperability because of the semantic differences of interpretation, complexity and width of scope. It is however an open question how to apply these techniques fruitfully in the eGovernment domain. This paper addresses the importance of providing a semantic application that, within the eGovernment domain, is capable of dealing with the issue of the retrieval of government documentation in a timely and accurate way. In this paper, we present an approach ontology-based for retrieving government information.
