【摘要】 以往的非结构化P2P系统采用的是无确定目标的自由搜索协议,它具有搜索效能低,无可扩展性的缺点。针对这些不足,提出一种非结构化对等语义连接网络(简称NSP-SLN),实现一个基于语义相似度的查询路由算法。仿真实验结果表明,语义拓扑能够有效地提高系统的搜索效率。更多还原

【Abstract】 Former unstructured P2P systerns adopting a free search protocol have no certain target,resulting in low search capability and no scalability.In allusion to deficiencies,brings forward the NSPSLN achieve the query routing algorithm based on semantic similarity.Experimental results show that searching in semantic overlay greatly improves the efficiency of search.更多还原
