李宝 《新世纪图书馆》2021,(4):68-75

用户画像作为大数据分析背景下个性化推荐服务的设计工具,为高校图书馆领域个性化阅读资源推荐服务提供解决思路。本研究在分析目前个性化推荐和用户画像研究的基础上,引入用户画像技术,从数据基础层、数据处理层、画像构建层、画像服务层设计探讨用户画像的构建流程,重点在用户画像构建和画像服务层面进行阐述,同时从用户基本属性、阅读状态、学习风格、阅读偏好四个维度构建用户多维画像模型,并提出基于冷启动和用户阅读学习过程画像的个性化推荐服务策略,以期为后疫情教育环境下高校图书馆开展个性化资源推荐服务和满足用户多维度阅读学习需求提供参考。  相似文献   

高校图书馆信息共享空间用户交互学习行为分析     

胡昌平  胡媛 《中国图书馆学报》2014,40(4):16-29

本文通过扩展TAM技术接受模型,探索高校图书馆信息共享空间中用户交互学习行为的影响因素。在结合高校图书馆信息共享空间具体环境的基础上,运用结构方程模型方法进行研究。研究发现:感知有用性、感知易用性和感知激励是用户交互学习行为的直接影响因素;感知易用性和感知激励显著影响感知有用性;用户特质、社会身份和服务内容显著影响感知激励和感知易用性,并通过它们影响用户交互学习行为;服务能力通过感知激励影响用户交互学习行为。图2。表6。参考文献62。  相似文献   

基于OPAC统计数据的借阅率提升策略探讨     

孟德泉  董颖  沙娅弘  孟桂荣 《大学图书馆学报》2014,32(5):73-78

目前图书馆馆藏资源的借阅率普遍偏低,利用布拉德福定律对外借图书进行分区,可以发现导致低借阅率的影响因素,提升馆藏图书的利用率。该文借助问卷调查,利用主成分分析方法得出影响用户借阅行为的因素:作者、出版社、出版日期等。选取"TP313汇编程序"这一领域的外借图书数据,首先利用定量分析方法和专家咨询方法验证前述因素如何影响图书的外借率,然后根据研究结果提出具体建议。  相似文献   

基于大数据的图书馆个性化服务安全体系构建研究     

陈臣 《新世纪图书馆》2014,(11):47-51

由于大数据的多数据性和复杂性,在大数据环境中频繁出现不可预测的攻击行为,且大数据导致的隐私泄露给用户带来了严重危害,错误数据将导致大数据分析结果不正确。为了保障图书馆大数据计算的安全,结合大数据安全的研究和可信云的概念,论文提出一种基于大数据的图书馆个性化服务安全体系。该系统模型可以有效地提升大数据的数据安全性,降低黑客恶意攻击行为有效性,从而提高图书馆大数据的分析效率。  相似文献

An investigation of the search behaviour associated with Ingwersen’s three types of information needs     

Pia Borlund  Sabine Dreier 《Information processing & management》2014

We report a naturalistic interactive information retrieval (IIR) study of 18 ordinary users in the age of 20–25 who carry out everyday-life information seeking (ELIS) on the Internet with respect to the three types of information needs identified by Ingwersen (1986): the verificative information need (VIN), the conscious topical information need (CIN), and the muddled topical information need (MIN). The searches took place in the private homes of the users in order to ensure as realistic searching as possible. Ingwersen (1996) associates a given search behaviour to each of the three types of information needs, which are analytically deduced, but not yet empirically tested. Thus the objective of the study is to investigate whether empirical data does, or does not, conform to the predictions derived from the three types of information needs. The main conclusion is that the analytically deduced information search behaviour characteristics by Ingwersen are positively corroborated for this group of test participants who search the Internet as part of ELIS.  相似文献   

Users as innovators in developing countries: The global sources of innovation and diffusion in mobile banking services     

Paul van der Boor  Pedro Oliveira  Francisco Veloso 《Research Policy》2014

This paper examines the extent to which users in developing countries innovate, the factors that enable these innovations and whether they are meaningful on a global stage. To study this issue, we conducted an empirical investigation into the origin and types of innovations in financial services offered via mobile phones, a global, multi-billion-dollar industry in which developing economies play an important role. We used the complete list of mobile financial services, as reported by the GSM Association, and collected detailed histories of the development of the services and their innovation process. Our analysis, the first of its kind, shows that 85% of the innovations in this field originated in developing countries. We also conclude that, at least 50% of all mobile financial services were pioneered by users, approximately 45% by producers, and the remaining were jointly developed by users and producers. The main factors contributing to these innovations to occur in developing countries are the high levels of need, the existence of flexible platforms, in combination with increased access to information and communication technology. Additionally, services developed by users diffused at more than double the rate of producer-innovations. Finally, we observe that three-quarters of the innovations that originated in non-OECD countries have already diffused to OECD countries, and that the (user) innovations are therefore globally meaningful. This study suggests that the traditional North-to-South diffusion framework fails to explain these new sources of innovation and may require re-examination.  相似文献   

Countering user risk in information system development projects     

《International Journal of Information Management》2014,34(4):533-545

User related issues have long been broadly discussed in the information system development (ISD) project research area. In this study, we focus on user risk and identify two risk countering approaches to demonstrate how to deal with user risk and its negative impact on ISD projects. We hypothesize that (1) user risk has a negative impact on project performance, (2) users’ bond with the project and the development team can help reduce user risk, and (3) developers’ task knowledge and vertical coordination can ease the negative impact of user risk and increase project performance. A quantitative approach with survey data collected from 240 practitioners confirmed our hypotheses. In addition, we interviewed seven developers and three user representatives to complete our understanding of this issue. Implications for academia and practitioners are discussed at the end of this paper. Suggestions for future research directions are also provided.  相似文献
