基于社交网络的个性化知识服务模型研究

通过对社交网络所产生的海量用户以及数据的挖掘与分析,判断用户不同的特征与喜好,从而为用户定制个性化知识服务,达到用户的需求,增强其对产品与服务的使用黏性,这不仅满足了企业的商业目的,同时也提高了用户的满意度。论文在深入了解我国社交网络的运营模式、分析社交网络中用户行为特征的前提下,提出从用户兴趣模型出发的个性化知识服务,并建立了基于个人兴趣和兴趣传播推荐的个性化知识服务模型。     

Open to suggestions: How organizations elicit suggestions through proactive and reactive attention

This paper analyzes organizations’ attempts to entice external contributors to submit suggestions for future organizational action. While earlier work has elaborated on the advantages of leveraging the knowledge of external contributors, our findings show that organizational attempts to attract such involvement are likely to wither and die. We develop arguments about what increases the likelihood of getting suggestions from externals in the future, namely through (1) proactive attention (submitting internally developed suggestions to externals to stimulate debate) and (2) reactive attention (paying attention to suggestions from externals to signal they are being listened to), particularly when those suggestions are submitted by newcomers. Findings from an analysis of about 24,000 initiatives by organizations to involve external contributors suggest these actions are crucial for receiving suggestions from external contributors. Our results are contingent upon the stage of the initiative because organizations’ actions exert more influence in initiatives that lack a history of prior suggestions. Our work has implications for scholars of open innovation because it highlights the importance of considering failures as well successes: focusing exclusively on initiatives that reach a certain stage can lead to partial or erroneous conclusions about why some organizations engage external contributors while others fail.     

A hierarchical network-oriented analysis of user participation in misinformation spread on WhatsApp

WhatsApp emerged as a major communication platform in many countries in the recent years. Despite offering only one-to-one and small group conversations, WhatsApp has been shown to enable the formation of a rich underlying network, crossing the boundaries of existing groups, and with structural properties that favor information dissemination at large. Indeed, WhatsApp has reportedly been used as a forum of misinformation campaigns with significant social, political and economic consequences in several countries.In this article, we aim at complementing recent studies on misinformation spread on WhatsApp, mostly focused on content properties and propagation dynamics, by looking into the network that connects users sharing the same piece of content. Specifically, we present a hierarchical network-oriented characterization of the users engaged in misinformation spread by focusing on three perspectives: individuals, WhatsApp groups and user communities, i.e., groupings of users who, intentionally or not, share the same content disproportionately often. By analyzing sharing and network topological properties, our study offers valuable insights into how WhatsApp users leverage the underlying network connecting different groups to gain large reach in the spread of misinformation in the platform.     

基于用户画像的高校图书馆精准服务构建

图书馆精准服务是"互联网+"时代的图书馆发展的必然趋势,要实现"精准"必须关注的基础就是用户。文章在对用户画像理念及国内外研究梳理的基础上,从现有大数据利用状况、主观上精准服务转型的需要和客观上该技术执行可行性三方面分析用户画像技术实现高校图书馆精准服务的可行性。最后在搭建图书馆精准服务架构系统的基础上,提出围绕用户画像实现高校图书馆精准服务的技术过程。     

OA系统应用开发中用户测试初探

OA系统成功应用的关键,在于最终是否满足了应用者的‘口味’,不同单位有不同的管理需求,必然决定了OA系统的个性化特性,不可能存在通用的OA系统产品,因而用户测试对OA系统项目实用化具有不可替代、不可跳越的关键性作用。本文对用户测试的步骤和方法做了初步的探讨。

国内外图书情报领域用户研究内容分析

本文以我国图书情报领域18种CSSCI源刊及《图书情报学文摘数据库》（LISA）为信息源,分别检索2007-2010年间国内外图书情报领域发表的与用户研究相关的学术论文。而后利用JDK1．6和MySQL Server5．0等软件,开发共词矩阵生成、关键词粘合度计算、关键词类团密度和向心度计算等程序。在此基础上通过共词分析和粘合度计算方法确定国内外图书情报领域用户研究的主流研究主题,并通过绘制主题战略坐标图考量不同研究主题的发展情况及其研究地位。最后通过对国内外相关研究内容的对比分析,对我国在该领域的研究提出发展建议。
