摘　　要：对等计算作为学术界和工业界的关注焦点,其在实践中的重要应用主要是信息资源共享.但随着对等计算信息检索系统的广泛应用,如何对其进行客观公正的评价,确定有效、实用的评估标准已迫在眉睫.于是,在以上趋势背景下,文章经过详细研究分析对等计算的信息共享系统后,指出目前P2P信息检索系统面临的实现机制和关键技术问题.之后,经过认真总结和分析,勾勒出评价系统性能的四项指标体系,提出系统性能评估的CTL定律,这对P2P信息检索系统的评价和开发将具有实际指导意义.同时,在此基础上确定今后对等计算信息检索系统研究工作的重点--关键技术及其相应策略.As a hot spot in the computer research and industrial fields,P2P has been mainly applied to information sharing.With P2P-based information retrieval systems applied frequently,the coming issues are how to evaluate the system objectively and fairly,and how to plot the common criteria for system performance evaluation.After having conducted a comprehensive study on P2P-based systems,we point out the implementation mechanism and key techniques in this area.We propose a novel approach to evaluate information retrieval systems based on P2P: Constraint Triangle Law,which will guide the development and evaluation of P2P-based information retrieval systems in the future.Furthermore we fix the key-point research on P2P-based systems: key techniques and strategies.
