TSPN: Term-based semantic peer-to-peer networks
Guoqiang Gao, Ruixuan Li, Zhengding Lu · Wuhan University Journal of Natural Sciences · 2012
In this paper, we propose Term-based Semantic Peerto-Peer Networks (TSPN) to achieve semantic search. For each peer, TSPN builds a full text index of its documents. Through the analysis of resources, TSPN obtains series of terms, and distributes these terms into the network. Thus, TSPN can use query terms to locate appropriate peers to perform semantic search. Moreover, unlike the traditional structured P2P networks, TSPN uses the terms, not the peers, as the logical nodes of DHT. This can withstand the impact of network churn. The experimental results show that TSPN has better performance compared with the existing P2P semantic searching algorithms.
