ABSTRACTAbout twenty years ago, the Internet began to change the way people create, access, publish, and share information. The impact of this information revolution has been felt in every industry. For instance, the Internet has enabled new models in the publishing sector, which has subsequently impacted education and changed the landscape of teaching and learning. About a decade ago, the introduction of new buzzwords such as open access, electronic publishing, digital humanities, and digital scholarship continued to challenge the scholarly production and dissemination of knowledge. Undoubtedly, these changes also created new opportunities for collaboration among multidisciplinary groups including researchers, scholars, students, technologists, librarians, and others. In this article, the author discusses four successful faculty-driven digital scholarship projects that his library system has supported in the last two years. His team's work serves as an example of how academic libraries and centers for digital scholarship at undergraduate institutions can support digital humanities and digital scholarship initiatives. Additionally, the case examples can contribute to the ongoing discussion of new roles for librarians and technologists in working with scholars and students to gain the skills necessary to implement digital scholarship projects. 相似文献

This paper presents a review of open data research based on bibliometric analysis of publications in Web of Science from 1998 to 2016. It shows that research on open data has grown rapidly since 2009 with the development of various open data initiatives. We identify the different themes using science mapping and performance analysis. The most important themes are semantic web, open government, and crowdsourcing. The basic and transversal themes are data sharing and public sector information. As for the emerging themes, these are Big Data and open government data. In addition, data journalism, monitoring, and recommender systems are specific themes that deserve special attention. The UK and the USA are the leading publishing countries, both in theoretical and practical research on open data. In China, most researchers focus on practical research, and there have been efforts to promote the development of open data. Papers introducing large‐scale projects receive more attention and citation quickly. Recently, researchers have been publishing more on objective topics, including possible issues and dilemmas in the era of Big Data and many problems such as budgets, ownership, licensing, culture, and sustainable development. 相似文献

基于本体的数字图书馆检索模型研究(Ⅲ)——历史领域资源本体构建 总被引：11，自引：3，他引：11
近些年来,本体(Ontology)已经在知识工程、人工智能、语义网等相关领域得到了广泛关注和深入研究。目前在数字图书馆领域,本体资源仍然是种稀缺资源。作为“基于本体的数字图书馆信息检索模型”研究课题的一部分,我们构建了“国共合作”历史领域本体,希望利用本体的思想和方法来对数字图书馆中的人文历史学科资源进行知识组织和知识表现。本文将介绍我们在历史领域本体构建方面所进行的工作,探讨在领域本体构建过程中所遇到的问题及其解决方法,希望我们所做的工作能为数字图书馆相关领域的本体构建研究提供有价值的参考。 相似文献

Digital libraries aim at unhindered access to content over computer and communication networks, and digitization may be taken as a visible proposition to enhance the shelf life of non-digital content by preservation apart from the virtue of increased and easy access, thereby furthering usage. As a fresh, lively and dynamic area with a lot of enthusiasm and activity by researchers from different disciplines, institutions and countries, digital libraries are viewed in different perspectives and the single most development that has brought about sweeping changes in the library and information discipline currently in the developed world is that of digital libraries. Advancements in computer and information technology with breakthroughs in memory technology has not only reduced the cost of infrastructure required for hosting digital libraries, but the demonstrated success of a wide variety of projects in USA and Europe also endorsed the chances of their survival even in a developing country. Though the professionals and libraries in developing countries are also experiencing the virtues of Internet, and electronic information highways, many of these libraries have not gone much farther than the computerization of in-house operations, availing databases in electronic media such as CD-ROMs, and web access of subscribed journals and various free resources. Digital library development should be taken up as an additional task to populate the web sites with valuable in-house content like the research reports, publications of in-house researchers, and so on. Digital library projects and developments in the country are so many, though a large number of them are only at an aggressively enthusiastic preliminary stage. In a country such as India so rich in content of indigenous research and development in disciplines varied from science and technology to social science, humanities and spirituality, there is tremendous need for hosting full fledged digital libraries by appropriately tagging the content with affordable information technology. However, what is lacking, especially in developing countries, is a coordinated collaborative approach to bring in institutions and identifying content valuable for digitization with sufficient monetary and infrastructure support. The digital library development in the country needs a two-pronged strategy (i) to digitize local content, and (ii) to devise options for accessing external resources. Channels for internal content include journals and serials for research, conference proceedings, theses and dissertations and preprints, research and status reports, textbooks and learning materials, government publications, spiritual/heritage sources, tourism information, traditional knowledge, etc. As far as external resources are concerned, there are electronic options from publishers and information provides such as, online access through Web of subscribed journals, CDs and floppies containing supplementary material of printed books, bibliographic/full-text databases, which can be hosted on library servers or intranet along with local content. The problems for digital library development are manifold in India such as lack of interest, non-availability of computer and IT infrastructure for library activities, copyright problems, ensuring secure access, properly selecting content from the mass available, internet bandwidth, absence of sufficient financial support, over concentration of professional time on administrative routines, acute shortage over concentration of professional time on administrative routines, acute shortage of competent manpower, etc. The software boom engulfing the country, as a result of the big leap in computer penetration, sudden rise in proficient manpower, and sizable improvement in communication infrastructure should also be treated as an asset and taken advantage of by authorities and information professionals to create and maintain digital information facilities to usher in the new information age. 相似文献
