选择与转换:复杂任务情境下用户搜索策略的运用

Choice and Transformation: The Application of User Search Strategies in Complex Task Situations

[目的/意义]信息搜索过程中搜索策略的运用是复杂动态的,研究复杂任务情境下用户搜索策略运用规律具有重要的理论和现实意义。[方法/过程]文章开展了基于复杂任务的搜索实验,利用录屏软件收集搜索行为数据,深入分析了不同任务情境下不同搜索能力用户搜索策略运用的差异以及常见的策略转换模式。[结果/结论]高低搜索能力的用户搜索相同类型的任务时策略运用存在差异,相同搜索能力用户搜索工作和生活任务时策略运用也存在差异,任务类型影响搜索策略运用的时长,此外,高低搜索能力的用户在搜索不同类型任务时存在不同的策略转换模式。

[Purpose/significance]The application of search strategy in the process of information search is complex and dynamic.It is of great theoretical and practical significance to study the application rules of user search strategies in complex task situations.[Method/process]This paper carries out a search experiment based on complex tasks,using the screen recording software to collect search behavior data,and deeply analyzes the differences in the application of different search ability users’search strategies and the common strategy conversion modes under different task situations.[Result/conclusion]Users with high and low search ability have different strategies when searching for the same type of task.The same search ability users also have different strategies when searching for work and life tasks.The task type affects the duration of the search strategy.In addition,users with high and low search capabilities are searching.There are different policy conversion modes for different types of tasks.
