| 摘 要： | 在综述相关研究的基础上,认为信息需求研究整体上已完成认知转向,初步形成以刺激(情境)-认知模型(信息需求)-反应(信息行为)为基本框架的研究模式,并在信息需求的认知本质、情境和理论体系构建等方面取得较大的进展,同时也存在认知模型构建等难点和挑战。综合分析信息检索技术发展的需要和研究现状,认为下一阶段信息需求研究将在持续发展认知导向理论研究的同时加强应用研究,并将重点围绕情境化、认知模型及其驱动的信息检索系统等开展研究。

| Abstract: | By reviewing the research on information needs (IN), this paper concludes that it has turned to a cognition-oriented phase as a whole and formed a research mode which basic framework are stimuli (contexts)-cognitive models (information needs)-reaction (information behaviors). The research has gained a considerable development on the cognitive essential, the context, and the theory of IN, and exposed difficulties and challenges such as cognitive models. Based on the analysis of demands and research status of information retrieval (IR) technologies, this paper believes that the IN future research will continue to research cognitive-oriented theory and promote the applied study. It also focuses on the contextualized IN research, cognitive models, and the cognitive-model-driven IR systems in the future. |
