搜索引擎用户行为与用户满意度的关联研究

Analysis into the Relationship Between Search Engine User Behavior and User Satisfaction Evaluation

用户满意度是以用户为中心的搜索引擎性能评价的一个重要分支,区别于传统基于查询与文档相关性的评价方法,基于用户满意度的性能评价能够更加全面、客观地对搜索引擎性能进行评价。该文通过设计搜索实验平台,在尽量不影响用户正常搜索过程的前提下收集用户的搜索行为及其满意度评价,通过用户行为分析的方法挖掘用户群体行为特征与用户查询满意度之间的关联关系。相关结论对提高搜索引擎性能、改善用户查询体验具有一定的参考意义。

As an important category of traditional work in search engine evaluation, user satisfaction evaluation has many differences from traditional relevance measurement evaluation. User satisfaction is a more user-centered evalu- ation, providing a global and systematic evaluation to the performance of search engine. This paper describes the re- lationship between search engine user behavior and user satisfaction evaluation. We designs an experiment with the premise of avoiding impacting user searching experiences, through which we collected query-level explicit judgments of user satisfaction and user behavior log, then analyzes the collected data to elicit valuable conclusions. The findings provide＇insights into the improvement of the performance of search engine and the amelioration of user searching ex- perlences
