| 摘 要： | 信息检索评价得到了学者们的广泛研究，而从用户认知的角度来对其进行研究逐渐成为学者们追捧的热点。本文从用户认知的角度出发，借助布鲁克斯提出的对数透视法思想，对目前比较常用的评价指标进行了改进，将物理世界（“世界1”）中的评价指标通过“对数尺”转换到了“世界2”和“世界3”的精神世界，从用户所获取的情报量对其检索结果进行了评价，克服了以文献数量为计量单位评价的不足。同时，通过应用分析对其改进的评价指标进行了说明。最后提出了本研究的不足和需要改进的地方。

| Abstract: | Information retrieval evaluation has been widely researched to scholars,the research from the perspective of cognitive has gradually become a hot pursuit of the scholars.Based on logarithmic law proposed by Brooks,this paper made some changes to commonly used evaluation index,from the perspective of user cognition,change evaluation measures in material "world 1" to spiritual "world 2" and "world 3" by logarithmic law,evaluated result by information amount instead of the number of documents.At the same time,the article did a application analysis to explain the changes and pointed out the deficiency and what should do at last. |
