Multi-Data Source Fusion Approach in Peer-to-Peer Systems

In this paper, a new approach for data fusion in the context of schema-based Peer-To-Peer (P2P) systems is proposed. Schema-based systems manage and provide query capabilities for (semi-)structured information: queries have to be formulated in terms of schema. Schema-based P2P are called Peer Data Management system (PDMS). A challenging problem in a schema-based Peer-To-Peer (P2P) system is how to locate peers who have data relevant to a given query. The proposal lies in application of the multi-data source fusion approach in the context of PDMS. Multi-data source schemas, distributed, shared and maintained by peers, are the basis of a semantic overlay network.
