Exploiting Peer Ontologies for Semantic Query Propagation ? (Extended Abstract) ??

A challenging issue to advance the existing P2P query prop- agation protocols is related to the capability of developing a routing mechanism where a semantically rich description of the context of each peer is explicitly taken into account for selecting the query recipients. In this paper, we present the H-Link semantic routing approach designed to exploit peer ontologies and ontology matchmaking results for provid- ing a semantic overlay network where peers having similar contexts are recognized and interlinked as semantic neighbors.
