A challenging problem in a schema-based peer-to-peer (P2P) system is how to locate peers that are relevant with respect to a given query. In this paper, we propose a new semantic routing mechanism in the context of the SenPeer P2P Data Management System (PDMS). SenPeer is an unstructured P2P system based on an organization of peers around super-peers according to their semantic domains. Our proposal is based on the use of a distributed data structure, called expertise table, maintained by the super-peers and describing data at the neighboring peers. This table, combined with matching techniques, is the basis of a semantic overlay network. Semantic links are exploited for efficient query propagation towards peers that may have relevant data. We give a performance evaluation of our semantic query routing with respect to important criteria such as precision, recall and number of messages. The results show that our algorithm significantly outperforms a baseline algorithm without semantics.
