Managing application domains in P2P systems

Peer-to-peer (P2P) systems provide shared access to resources that are spread over the network. In such scenario, files from the same domain can be found in different peers. When the user poses a query, the processing relies mainly on the flooding technique, which is quite inefficient for optimization purposes. To solve this issue, our work proposes to cluster documents from the same domain into super peers. Thus, files related to the same universe of discourse are grouped and the query processing is restricted to a subset of the network. The clustering task involves: ontology generation, document and ontology matching, and metadata management. This paper details the ontology generation task. The proposed mechanism implements the ontology manager in DetVX, a framework for detecting, managing and querying replicas and versions in a P2P context.
