摘要: 任务是用户进行信息搜寻的原动力,是影响信息搜寻的主要因素。在阐述任务概念及类型划分现状的基础上构建信息搜寻行为中任务的框架。任务内部基本特征包括目标特征、路径特征和结果特征;任务外部特征重点强调任务执行者特征中已有知识及认知需求的影响。综合任务的内外特征再确定任务类型,探讨其与信息搜寻行为之间的影响关系,最后提出基于任务框架的主要研究问题。

关键词: 任务层次, 任务类型, 任务框架, 信息搜寻行为, 认知需求

Abstract: As the driving force of users' information seeking, task is the main factor affecting information seeking. Based on introducing the research status of task concepts and types, this paper proposes a task framework for information seeking behavior, that is internal basic characteristics of task include objectives, paths and outcomes. Then it extracts complex characteristics of task such as complexity, structural, etc. External characteristics of task emphasize on influences of performer characteristics of prior knowledge and cognition needs. Integrating internal and external task characteristics, this paper determines the type of task, explores the relationship between task and information seeking behavior. Finally, it proposes main research issues based on the task framework.

Key words: task level, task type, task framework, information seeking behavior, cognition need
