不同任务情境下研究生网络信息搜寻行为特征与差异研究

Research on Characteristics and Differences of Postgraduate Online Information Seeking Behavior under Different Task Contexts

基于任务的用户信息搜寻行为研究一直是信息行为研究领域关注的热点。本文以研究生群体为研究对象,设置购物型、旅游型、科研型和健康型4种任务情境,采用模拟实验法、观察法、问卷调查法等多种研究方法,探讨不同任务情境中用户信息搜寻行为的行为模式与差异。结果显示,在不同任务情境中,用户的网络信息搜寻行为在信息源的选择行为、查询检索式的构造行为、网页浏览与结果选择行为和任务搜寻时长等方面具有显著差异。另外,用户在不同情境下任务的主题熟悉度、难度、复杂度、进度和满意度感知也具有显著差异。本研究有助于丰富网络用户信息搜寻行为研究领域的实证研究基础,也有助于优化信息搜寻平台的设计和内容组织,提升用户信息搜寻体验。

Research on information seeking behavior is one of the core research areas of user information behavior.In this study,we investigated how postgraduates do the online information seeking under different task domains(shopping,travel,research and consumer health)to identify differences in searching needs,subjects and several methods were adopted,including the simulation laboratory experiment,observation method,questionnaire survey and semi-structured interview method.This study focuses on the whole complete process of user information seeking behavior.The results show that in different task situations,the user’s online information seeking behavior have significant differences in the selection behavior of the information source,the construction behavior of the query and retrieval,the web browsing and result selection,and the search duration.In addition,the user’s subject familiarity,difficulty,complexity,progress,and satisfaction perception are significantly different in different contexts.This research will help to enrich the empirical research foundation of the field of information seeking behavior,and also help to optimize the design of the information search platform and enhance the users’ information seeking experience.
