论网络化环境下的用户信息需求 总被引：51，自引：5，他引：46
面向21世纪的社会发展,信息网络化交流和信息资源开发、组织与利用的网络化业已构成了用户信息需求的新环境。在社会信息化和信息社会化的综合作用下,用户信息需求处于不断变革之中,由此决定了网络化时代信息服务的基本组织模式。基于这一认识,本文从分析网络化环境下用户信息需求特点和演化出发,研究了网络化中用户信息需求的内容与结构,探索了以用户信息需求引动为中心的网络化信息眼务的优化以及我国的基本对策。 相似文献

This article explores how to develop complex data driven user models that go beyond the bag of words model and topical relevance. We propose to learn from rich user specific information and to satisfy complex user criteria under the graphical modelling framework. We carried out a user study with a web based personal news filtering system, and collected extensive user information, including explicit user feedback, implicit user feedback and some contextual information. Experimental results on the data set collected demonstrate that the graphical modelling approach helps us to better understand the complex domain. The results also show that the complex data driven user modelling approach can improve the adaptive information filtering performance. We also discuss some practical issues while learning complex user models, including how to handle data noise and the missing data problem. 相似文献

针对传统检索方法在当今网络信息环境下所面临的问题,提出了一种用户个性化信息检索新方法。在这种方法中,根据形式概念分析(FCA)理论,将用户偏好定义为概念网,用户概念网中的概念定义了用户偏好的范围和目标。使用传统的TF-IDF加权方案和ODP的参考概念层次,将用户偏好用概念矢量表示,进行用户概念网的扩展。比较测试表明所提出的方法不仅具有实现可行性,而且在检索效果上优于传统的检索模式,具有一定的应用前景。 相似文献

Participation in and adding content to social tagging tools is important for these tools to achieve their purpose of classifying and organizing information. Users of social tagging tools are driven to participate and add tags by extrinsic and intrinsic motivation. Extrinsic motivation is dominating research as a main predictor of why users use information systems. Social tagging tools, as a subset of social media tools, are distinguished by their unique social aspect that makes intrinsic motivation a potential driver for users to add tags to content. Intrinsic motivation, when applied to social tagging tools, could entail many shades that represent different users’ motives for using such tools. In this paper, we add a rich concept of intrinsic motivation to include hedonism as a main predictor of users’ behavior on social tagging tools. We empirically validate a previously proposed theoretical model of three dimensional concepts of hedonism with three components describing individuals’ hedonic state when interacting with social tagging tools: explorability, curiosity, and enjoyment. After a robust and thorough data analysis using structured equation modeling, the results confirm our theoretical model and suggest using a richer concept of enjoyment to reflect a hedonic dimension when investigating intrinsic motivation with interactive social media tools. Our validated model could be the spark of new factors that have the potential to influence user acceptance of information systems in general and in social media tools. This research contributes to the development of attitude-behavior theories that could explain users’ acceptance of dynamic web 相似文献

In this paper, we present the state of the art in the field of information retrieval that is relevant for understanding how to design information retrieval systems for children. We describe basic theories of human development to explain the specifics of young users, i.e., their cognitive skills, fine motor skills, knowledge, memory and emotional states in so far as they differ from those of adults. We derive the implications these differences have on the design of information retrieval systems for children. Furthermore, we summarize the main findings about children’s search behavior from multiple user studies. These findings are important to understand children’s information needs, their search strategies and usage of information retrieval systems. We also identify several weaknesses of previous user studies about children’s information-seeking behavior. Guided by the findings of these user studies, we describe challenges for the design of information retrieval systems for young users. We give an overview of algorithms and user interface concepts. We also describe existing information retrieval systems for children, in specific web search engines and digital libraries. We conclude with a discussion of open issues and directions for further research. The survey provided in this paper is important both for designers of information retrieval systems for young users as well as for researchers who start working in this field. 相似文献
