摘　　要：指出在网络受控环境下,用户主观因素是影响信息检索绩效的重要变量,在信息检索过程中发挥着至关重要的作用。利用CCA典型相关分析方法,分析主观因素与检索行为等因素之间的关系。结果表明:①容易度与任务总时间显著相关,当用户在检索后判断任务难度大时将会付出更多的时间和努力;②标记文献数、重复浏览率、浏览网页数与感觉、丢失度相关;③高兴度与相关度、完成度负相关表明用户在检索前愉悦程度低的用户可能获得更好的检索结果。In the network controlled environment, user subjective factors are important variables that affect the performance of information retrieval. With the CCA canonical correlation analysis methods, we analyzed the relationship between the subjective factors and the other factors. The results showed that： The difficulty and the total task time was significantly related. When the users regard the retrieval task as difficult , they will pay more time and effort; ②The number of markup documents ,the rate of repeat visitors, the number of browsing the page were significantly related with feelings and loss. ③The degree of happiness is inversely related to the degree of correlation and completion, which indicating that before retrieving the user with the lower degree of pleasure may get better search results.
