[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] To explore the influence of user search ability and task type on exploratory search behavior, and to further explore exploratory search in order to provide reference for establishing and perfecting exploratory search system and constructing exploratory search behavior model. [Method / Procedure] This paper designs one question-answering search task and two exploratory search tasks of different complexity, and groups the experimenters according to the search ability to carry out the search experiment. Through the analysis of the questionnaire, browser log analysis and search process video, this paper analyzes the search tools, search terms, search actions and web pages in exploratory search activities from two aspects: search tasks and users. [Results / Conclusions] Search capabilities and task types have had varying degrees of impact on exploratory search behavior. The more complex the task, the more in-depth exploration. The higher the search capability, the more active the search process. In addition, it also summarizes the dynamic evolution of search-based information needs and the advancement of search path.
