Exploiting wordnet for semantic routing in unstrutured peer to peer information retrieval
Naomie Binti Salim · 2008
Unstructured peer-to-peer networks offer attractive benefits in large-scale information retrieval and search systems because of its fault-tolerance, scalability and decentralization. However, its architecture makes it hard to share useful semantic knowledge among peers. In this paper we propose a semantic based method for unstructured peer-to-peer query routing. Here we exploit the semantic correlation among peers based on the query terms. The term expansion mechanism is the key part of this approach where the term is expanded based on the use of WordNet. Simulation results show that, our approach improves the retrieval and use small number of messages in query routing and retrieval.
