摘要：The information integration systems consist in offering a uniform interface, to provide access to a set of autonomous and distributed information sources. The most important advantage of an information integration system is that allows users to specify what they want, rather than thinking about how to get the responses. The studies in this field have aimed at developing tools allowing a transparent access to data sources disseminated on a network. In particular, there are two major classes of integration systems: the mediation systems based on the paradigm mediator/Wrapper and peer to peer systems (P2P). Recently, other integration systems have emerged as P2P mediation systems. In these systems, the correspondence problem between schemas is a crucial problem. Especially as to integrate different sources requires the identification of the elements which can be dependent between the various diagrams. This is called correspondences or mapping between schemas. In this paper, we study this problem of mappings discovery and we present an approach of automatic correspondences discovery in a Pure Peer-to-Peer mediation system.
