Enforcing a semantic routing mechanism based on peer context matching

In this paper we present the main features of the H-LINK semantic routing mechanism we are developing to combine ontology-based peer contexts and ontology matching techniques for providing P2P query forwarding on a real semantic basis. H-LINK defines a semantic overlay network where each edge represents a semantic link between two peers having similar contexts. Semantic links are exploited to address query propagation by identifying the semantic neighbors that can provide relevant knowledge with respect to a given target request
