[目的/意义] 探究用户搜索能力和任务类型对探索式搜索行为的影响,进一步深入认识探索式搜索,以期为建立和完善探索式搜索系统、构建探索式搜索行为模型提供参考。[方法/过程]设计1 个提问应答式搜索任务和 2 个不同复杂度的探索式搜索任务,依据搜索能力对实验者进行分组,开展搜索实验。综合运用问卷调查、浏览器日志分析和搜索过程视频分析,从搜索任务和搜索能力用户两个角度,对探索式搜索行为中的搜索工具、检索词、搜索动作、网页4个方面进行分析。[结果/结论]搜索能力与任务类型对探索式搜索行为产生了不同程度的影响。任务越复杂,探索行为越深入。搜索能力越高,搜索过程越活跃。此外,还归纳了探索式搜索的信息需求演进的动态性、搜索路径的波动前进性等特点。

[Purpose/significance] This paper explores the impact of users' search capabilityand task type on exploratory search behavior and further understandexploratory search, to provide reference for establishing and improving the exploratory search systems, and constructing the model of exploratory search behavior.[Method/process] Onequestion-answering search task and twoexploratory search ones with different complexityaredesigned. Experiment participants areclassified into two groups according to theirsearch capabilities, and then the search experiments are carried out. The methods of questionnaire survey, browser log analysis and search process video analysis areused from two perspectives of search task and users' search capability. The depth analysis aredeveloped in four aspects, including search tools, search terms, search actions and webpage indexes. [Result/conclusion] Search capability and task type have positive effects on the depth and vitalityof exploratory search. Additionally, the characteristics of exploratory search such as the dynamics of information needs evolution and advancement of search path fluctuation arealso revealed.
Key words： exploratory search; search tasks; search capability
