当前,数字图书馆的信息环境已由信息不足转变为信息过载,其对应的服务模式也应由"人找信息"转变为"信息找人"。智能信息推荐服务的应用有助于应对新信息环境转变给数字图书馆带来的新挑战,但目前国内外对数字图书馆智能信息推荐服务满意度的影响机理尚缺乏深入研究。本文利用扎根理论方法,通过对访谈获取的原始资料进行编码分析,提炼出78个初始概念、24个基本范畴和6个主范畴。在此基础上,梳理范畴间的关系路径与作用机制,并构建了数字图书馆智能信息推荐服务满意度影响机理的理论模型。研究结果发现,在用户偏好的调节作用下,推荐系统质量、推荐信息质量、推荐服务质量和推荐形式共同对数字图书馆智能信息推荐服务满意度产生影响。本研究结果可为数字图书馆服务优化与良性发展提供有益参考,具有理论和实践意义。 相似文献

科技文献跨语言推荐模型研究 总被引：1，自引：0，他引：1
信息超载和语言障碍影响我国科研人员对外文科技文献的有效获取,如何提高获取效率成为亟待解决的问题。个性化推荐能很好地处理信息超载现象,但当前国内外相关研究都基于单一语种进行,多语种环境下的推荐研究非常缺乏。本文提出网络环境和海量数据背景下的科技文献跨语言推荐模型,并论证用户兴趣特征抽取、语言转换和混合推荐等步骤。利用Web日志挖掘技术,分析基于多种信息行为的整合分析方法抽取用户兴趣特征,以分类表作为参考体系建立用户兴趣表示模型,在用户—特征词转化为用户—类目矩阵的基础上开展推荐研究。 相似文献

This article describes a study of the two most popular plagiarism-detection software platforms available on today's market—Turnitin (http://www.turnitin.com/static/index.html) and SafeAssign (http://www.safeassign.com/). After a brief discussion of plagiarism's relevance to librarians, the authors examine plagiarism-detection methodology and conduct a review of the current literature regarding plagiarism-detection efficacy. To evaluate detection efficacy for Turnitin and SafeAssign, the authors constructed a brief study in which twenty sample papers containing portions of plagiarized material were submitted to each platform. The results show that Turnitin had the highest overall success at plagiarism detection with an 82.4 percent detection rate. Additionally, both platforms had a combined false-positive detection rate of 16.8 percent. The authors conclude that close review of material suspected of plagiarism is still essential for proper identification. 相似文献

Abstract The Russian government is exerting increasing control over the country's media, although the media are resisting. This government-media conflict is relevant to Western academics and libraries, because the variety and quality of Russian periodicals is at stake. In addition, if the media are constrained, publishers of books are likely to experience restrictions, too. The difficulties the government is having in controlling the media, however, are a measure of how much Russia has changed. At the same time this conflict is occurring, book publishing is thriving. Official statistics show the number of titles published surpassed even the previous record set in 1977. Planning is in progress to restructure the state book industry sector, including publishing, printing and distribution. Book prices have increased more rapidly than inflation, and postage costs have also increased. Russian Press Service is doing its best to keep its prices to Western libraries down. 相似文献

SUMMARY Describing her experience of establishing an Electronic Document Delivery Service at the library of the Lahore University of Management Sciences (LUMS), the author discusses the various issues, which significantly effect the net cost, delivery time and management process of providing such a service by a library in Pakistan. While presenting multiple options leading to an effective solution, the advantages and disadvantages of each option have been highlighted, and their implications, with particular reference to Pakistani libraries, have been discussed. The various points to be considered by Pakistani Librarians, while selecting a commercial Document Provider, have also been discussed. In the end, the author discusses the potential of using the Electronic Document Delivery facility as a time-saving and cost-effective tool for Resource Sharing among libraries in Pakistan. 相似文献

ABSTRACT No one can predict what document delivery will look like in the future, but librarians must guard patron confidentiality even in an electronic environment. This time it isn't an easily solved problem like finding another way of recording circulation than handwriting patron names onto circulation cards, it is instead the tracking of personal information attached to electronic text supplied by publishers that is a potential violator of patron privacy. Unmonitored in their efforts to protect their intellectual property without considering the rights of their customers, publishers could pose a threat to their customers' privacy, thus limiting their legal right of free access to information. Although encryption technology would appear to provide an answer to the confidentiality problem, it is not a panacea and that must be considered as the National Information Infrastructure is developed. Librarians need to stay alert to the developments in electronic publishing to be sure their concerns for patron privacy continue to be heard. 相似文献

ABSTRACTIn today's current political environment raising support for millage renewals, bond campaigns or even millage continuations for public libraries is affected by national politics, and a tendency towards tax aversion on principle across the country. The lessons we can learn from the governing boards of small and rural public libraries are worth raising up to a greater national consciousness. Board governance, community consciousness, and facilities management are clear and logical tools that elected boards of public libraries can use to politick for support of libraries. 相似文献

This article uses the metaphor of building to frame discussion about how we prepare for the provision of learning in the years
to come. The intention is to catalyze key conversations that will shape how, where, and why we learn. The principal focus
is on areas such as blended learning, mobility, gaming, social networking, holographics, analytics, and the human touch. However,
the larger theme involves challenging the reader to vision how we bring the best of traditional education forward, combine
it with new technologies and techniques, to reach and teach students well. 相似文献
