摘　　要：搜索引擎是信息时代人们获取所需信息的重要手段,搜索引擎性能度量方法也成为了一个重要的研究课题.本文分析了国内外搜索引擎检索性能度量的研究状况,提出了一种基于用户路径模型的性能度量方法.从用户搜索行为的角度研究了用户行为模型,通过抽象用户行为模型到路径模型的映射,给出基于用户路径模型的搜索引擎检索性能的评估步骤,针对度量数据给出了成功搜索度量方法,并通过度量平台的实现验证了该度量方法的实践意义.Search Engine is an important means, which people looked for their requirement information. Then the measurement methods also turn to an important research course. This article deeply analyses the development status of search engine retrieve performance measurement in the native and abroad, then a measurement method based user path model was established. The user action model was researched form user retrieve action, and then the user path map rule is put forward. Furthermore, the evaluation process of search engine retrieve performance was described, and defmed measurement method of successful search. Last, through the accomplishment of evaluation platform, the practice signification was proofed.

关 键 词：搜索引擎 检索性能度量 用户路径 成功搜索
