开放仓储目录是对开放仓储的描述说明和索引,是开放学术资源利用、发现、共享的基础。本文首先通过对OpenDOAR、ROAR、BASE等5个国际主流开放仓储目录的建设现状进行调研分析,发现在国际开放仓储目录建设方面,还存在仓储目录收录不够完整、目录元数据项不够丰富、目录更新时效性有待提高、揭示系统功能相对单一等不足。在此基础上,本文提出开放仓储目录元数据整合研究,包括元数据描述规范设计、基于OAI协议和ETL工具收割元数据,使用数据清洗工具OpenRefine对元数据进行“形式去重”和OAI-Identify获取结果的“内容去重”,并建立对多源异构仓储目录进行匹配融合的方法路径,形成数据内容更丰富、数量更加全面的全球开放仓储目录GOAR核心集和扩展集。最后从建立动态更新融合机制、常态化监控机制和目录发布系统三方面提出下一步研究方向。 相似文献

[目的/意义]构建多源文献元数据融合模型,有助于提升文献元数据整体质量,促进资源发现系统中的元数据管理与利用,优化用户资源发现服务体验。针对笔者此前提出的文献元数据判重策略进行优化,从经验为主向自动化转变,在保障判重和融合效果的前提下,提升整个过程的自动化水平。[方法/过程]针对不同类型文献的元数据项不一样、同一文献不同来源的元数据项不一样均会使得判重方法有所区别的情况,提出一种自动化的基于决策树的多源文献元数据融合模型,将判重问题转化为分类问题,根据特征相似度选择特征并构造决策树,在此基础上实施元数据判重及融合,并以不同类型的文献资源元数据为例进行实验,对策略进行效果验证。[结果/结论]结果显示,对于5种文献类型元数据,判重策略的准确率均达到99%以上,召回率均达到98%以上,总体效果较好。对于融合策略的效果判断,专利、学位论文、期刊论文、会议论文、图书的元数据项质量提升比例分别为15.15%、36.80%、15.29%、52.63%、15.38%,均有明显幅度的提升。 相似文献

古籍目录辨章学术,考镜源流,对古典学术研究具有重要的价值。本文提出古籍提要网络分析模型,用无向三部图整合古籍、人物和提要信息。在此基础上构建古籍目录智能分析工具,不仅可以自动挖掘提要中蕴藏的人物关系,与已有的古代人物知识库相关联,为知识库补充可靠而有价值的关系信息;而且综合考虑提要的元数据和正文的语义特征信息,并将其整合入推荐算法中,能为用户智能地推荐与被检索项内容、部类名、古籍名、古籍责任者相关的提要。以《四库全书总目》为实验数据集,一方面基于提要网络,从人物、古籍、提要三个层面探索不同实体间的内在联系,并就四部提要中出现的人名和古籍名开展定量研究;另一方面从作者简介、内容概述及学术评价这三种提要文本特征入手,结合元数据信息和三种常用的文献推荐算法,评估不同的语义特征对工具推荐功能准确性的影响。实验结果表明,提要文本中的内容概述及学术评价作为语义特征提炼,再结合元数据信息,效果良好,可推广应用到面向古籍的知识发现中。图4。表6。参考文献51。 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

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

The Book Industry Study Group and The Idea Logical Company carried out an online survey to capture publishers’ comments on
how market conditions were changing and what they are doing differently as a result of the economic pressures in the consumer
market. About 250 individuals responded to the online survey. Interviews were carried out of more than a dozen executives
at large and small publishers and their accounts to get further insights. The goal was to identify what are the sales conditions
for trade book publishers today and what publishers are doing to change sales and marketing and even editorial practices to
accommodate changing times. What we have learned from that joint effort is reflected in this article. 相似文献
