| 摘 要： | 针对对等网络中检索结果的重复问题，提出一种检索结果合并策略。介绍一种重复文档检测方法，对于重复文档，采用以减少下载数据量和下载响应时间为目的的下载节点选择方法及合并算法，有效减少检索结果的冗余度、下载数据的网络传输量和获取数据的响应时间。实验验证了该方法的有效性。 |
| 关 键 词： | 对等网络 信息检索 检索结果合并 |

| Abstract: | For the challenges of duplicated retrieval result in P2P networks, a mechanism to merge the retrieved results is proposed. A method of detecting duplicated results and a strategy of selecting download peers for duplicated results based on download data quantity and response time are presented. The strategy can efficiently reduce retrieval overlap, network transfers quantity for downloading results and response time for acquiring results. Experimental results show that the method is efficient. |
| Keywords: | P2P networks information retrieval retrieval result merging |
