摘要
任务难度是影响用户检索行为的重要因素之一。本研究对交互式信息搜索领域中涉及任务难度相关的研究进行了较为系统的调研和梳理,从任务难度的界定、测量、用户感知原因、任务难度与检索行为的关系,以及任务难度预测等方面对现有研究进展进行了分析。在总结概括的基础上,提出了进一步的研究问题。
The task difficulty is one of the important factors that affect the user's search behavior.This research systematically investigates and analyzes the researches related to task difficulty in the field of interactive information retrieval.It discusses from the definition,measurement of task difficulty,user perception reasons,the relationship between task difficulty and search behavior,and task difficulty prediction.Based on those findings,it puts forward further directions in future study.
