本文提出并阐明了利用对等（P2P）技术的分布式信息检索（IR）方式，该方式具有与当前索引集成搜索引擎利用统计信息计算内容近似相同的准确率。要实现利用统计信息的分布式信息检索系统，需要解决以下三个问题。第一种是从所有内容中统计信息的计算方式和分布式节点（节点）之间协作生成索引的方式。第二个问题是多环节点协作在逻辑空间上分配索引的效率问题。最后一个问题是高效、高准确度的IR策略。对于评估的结果，我们讨论的传播时间产生的统计信息和系统的可扩展性之间的关系，通过模拟和仿真。我们提出的系统适用于灵活的IR服务，适应内容环境从小型网络到中型网络，如办公室。
In this paper, we propose and clarify distributed information retrieval (IR) manner use of peer-to-peer (P2P) technology, which has the same accuracy approximately at current index-integrated search engine use of statistical information calculated from the contents. Realizing decentralized IR systems which uses of statistic information, we need to solve following three problems. First is the calculation manner of the statistic information from all content and generating indices manner by the collaboration among distributed peers (nodes). Second problem is the efficiency of index distribution on logical space collaborated by peers named multiple-ring. And the last problem is efficient IR strategies with high accuracy. As for the result of the evaluation, we discuss the relationship between the propagation time for generating the statistics information and the system scalability by simulation and emulation. And our proposed system is suitable for the flexible IR service which adapts contents environment from small scale network to middle scale network such as an office.
