摘要
为研究用户推荐对网络搜索行为的影响,将用户推荐加入到搜索引擎结果页面中,通过眼动跟踪技术观察被试在完成网络搜索任务时行为的变化.实验结果显示,加入用户推荐对被试的搜索效率、注意力分布和点击分布没有显著影响.但反馈问卷显示,多数被试认为用户推荐有助于搜索,并且会在搜索中参考该信息.分析发现,两种结果矛盾的原因在于被试在搜索过程中常常会忽略用户推荐,产生无意视盲(inattentional blindness)现象.
In order to investigate the impact of user recommendation on Web search behavior,the user recommendation was added to search engine results page（ SERP） and observe the change of a participant behavior during Web search via eye-tracking technology. Experimental results show that the additional user recommendation does not significantly influence search efficiency,attention distribution,and click distribution. However,the participant feedbacks indicate that most of them consider user recommendation useful and refer to it during Web search. The reason of this contradiction is that participants ignore user recommendation during search process,which is inattentional blindness.
