Description:
Unspecified Ontologies for P2P:
this approach premises that the domain ontology of an E-commerce application is not fully defined and parts of it can be dynamically specified by the peers. To implement semantic routing we extend a hypercube graph structure to a multi-layered hypercube (MLH), where each vertex recursively consists of another hypercube. We use hashing to deal with the unspecified nature of the ontology and with the variety of terms that can be used. This allows the peers to distributively manage a dynamically growing ontology and uniformly distributes the ads among the MLH. To eliminate ambiguity and enhance system precision, the terms used by the peers in the ontological description of an object undergo simple semantic standardization using WordNet.
