| 摘 要： | 对文献相关性判断中的首因效应及近因效应进行实验研究，并对文献数量是否影响用户相关性判断进行探索。经实验研究后发现：用户相关性判断不仅受文献呈现次序的影响，还受文献检出数量的影响；相关性判断中的近因效应不如首因效应明显和普遍。希望此研究结果能为完善信息检索系统的设计及评估，为信息检索系统的设计更符合以用户为导向的理念提供一些借鉴。

| Abstract: | Empirical study on primacy effect and recency effect in the relevance judgment is done in this study. In addition, the relationship between the number of document and user’s relevance judgment is also explored. Finally, the empirical study results show: relevance judgment is affected not only by document presentation order, but also by the number of document and primacy effect is more obvious and common than recency effect in relevance judgment. It is hoped that these findings can be helpful for information retrieval system design and appraisal, provide certain reference function to the information retrieval system design which meets more the idea of user guiding. |
