交互式信息检索中的一个重要问题是：任务特征如何影响用户的需求？在这篇文章中，我们研究了认知任务的复杂性对被认为对任务有用的信息类型的影响。我们从两个角度描述信息类型。从一个角度来看，我们根据固有特征(称为信息类型)对与任务相关的信息项进行分类：事实陈述、概念/定义、自以为是的陈述和洞察力-与任务领域相关的提示/建议。从第二个角度来看，我们使用Byström和J\“a rvelin的框架(Citebystom1995)来定义信息类型，基于如何使用信息来完成任务(称为功能角色)：(1)帮助任务实施者理解任务需求(问题信息)；(2)帮助任务实施者制定如何处理任务的策略(解决问题的信息)；以及(3)帮助任务实施者了解任务域(域信息)。我们的结果表明：(1)认知任务复杂性影响被认为对任务有用的信息项的功能角色(RQ1)；(2)某些信息类型更多(或更少)地扮演某些功能角色(RQ2)；以及任务复杂性影响信息类型所扮演的功能角色的多样性(RQ3)。
An important question in interactive information retrieval (IIR) is: How do task characteristics influence users' needs? In this paper, we investigate the effects of cognitive task complexity on the types of information considered useful for a task. We characterize information types from two perspectives. From one perspective, we classify task-related information items based on inherent characteristics (referred to as info-types): factual statements, concepts/definitions, opinionated statements, and insights---tips/advice related to the task domain. From a second perspective, we used Byströ m and J\"a rvelin's framework~\citebystrom1995 to define information types based on how the information might be used to complete the task (referred to as functional roles): (1) to help the task doer understand the task requirements (problem information); (2) to help the task doer strategize on how to approach the task (problem-solving information); and (3) to help the task doer learn about the task domain (domain information). Our results suggest that: (1) cognitive task complexity influences the functional roles of information items deemed useful for the task (RQ1); (2) certain info-types are more (or less) likely to play certain functional roles (RQ2); and task complexity influences the variety of functional roles played by info-types (RQ3).
