基于语义的对等网络检索机制(英文)

Efficient Semantic-based Content Search in P2P Network

提出了一个基于语义的分布式对等覆盖网络S-Peer。网络中的节点基于语义信息聚类,并自组织成一个语义覆盖网络。S-Peer网络构造了一个一维语义空间,避免了高维语义空间的维护开销,提高了资源检索效率。实验结果证明了该算法的有效性和灵活性。

Content-based full-text search is a challenging problem in Peer-to-Peer （P2P） systems. A distributed P2P overlay network that supports semantic-based content searches, called S-Peer, is proposed. Peers in this overlay are grouped based on the semantics of their data, and self-organized as a semantic overlay network. To reduce overheads incurred by peer joining and leaving in a high-dimensional overlay network, peers are constructed as a one-dimensional semantic space that facilitates efficient routing. The results show the effectiveness, efficiency and scalability of the proposed system.
