摘　　要：对查询重构行为和满意度的关系进行研究,包括查询重构情境、查询间隔时间、查询重构类型、点击网页数量,以及点击网页位置与满意度之间的关系,进而为查询系统优化提供依据。使用屏幕录像软件记录用户查询重构过程,采集实验数据。运用统计学方法分析查询重构行为变量与满意度的关系。结果显示:在原始查询存在满意结果情境下,查询重构满意度更高;查询间隔时间增加,满意度下降;不同查询重构类型下,用户满意度存在一定差异,其中详细化和平行移动查询重构满意度最高;用户点击结果列表页面越多,找到满意结果的概率越低;用户点击网页位置为2时,满意度比例最高,在点击位置大于2后,满意度随点击位置下降。The relationship between query reformulation behavior and user satisfaction is studied,which includes query reformulation context,query interval time,query reformulation type,the number of clicks,and the relationship between clicking location of the webpage and satisfaction. It can provide basis for optimizing the search system. The data of query reformulation process are recorded by screen video software and analyzed by statistical methods. The results are as follows. When the information need is fulfilled in the original query,the satisfaction is higher in the next query reformulation process. With query interval time increases,the satisfaction decreases. Uses’ satisfaction degrees are different under different query reformulation types,in which the satisfaction of specification and parallel movement is highest. The more clicks on search engine result pages,the lower probability of finding satisfactory results,and the probability of satisfaction is highest with two clicks on the search engine result pages.
