数字图书馆读者检索兴趣的智能分析算法 总被引：1，自引：0，他引：1
针对数字图书馆信息检索服务的智能化发展趋势,提出智能化信息检索服务中对读者检索兴趣进行智能分析的模糊匹配算法,主要思路是在系统中构建用户兴趣矩阵,在用户操作过程中动态构建用户行为矩阵,通过两者的模糊运算,获得用户的兴趣从属度,检索系统根据该从属度对检索结果进行动态优化并及时向用户推送,从而提升检索系统的智能化程度。

Open Access and the Developing World 总被引：2，自引：0，他引：2
Subbiah Arunachalam 《图书情报工作》2006,50(1):34-37
Till about 15 years ago, almost all information exchange among scientists and scholars was mediated by print and even then researchers in the developing countries were at a great disadvantage as their libraries did not have the resources to subscribe in comparison with even a small fraction of journals libraries in advanced countries. But the Internet and the World Wide Web initially exacerbated the gap between the rich and the poor countries, as many poor countries were slow to acquire these technologies and the infrastructure (especially bandwidth). Soon it became clear that thanks to these technologies we now have the unprecedented opportunity of having a level playing field in the matter of accessing scientific and scholarly information. Transforming this opportunity into reality is entirely in the hands of the researchers themselves. Imagine a world where every scientist places his/ her research papers, which (s)he wants to give away so others can read and make use of, in a public archive. Anyone anywhere in the world, of course having an Internet connection, can access, download, and read those papers. This is a win-win situation for all: the reader gets to read what he wants to read at very little cost; the author gains greater visibility for his work and the work reported is likely to have greater impact than if it were to be made available only through a toll-access journal. Although the logic is so simple, in reality such archives were not coming up for a very long time. In spite of the fact that computer scientists and physicists had shown about 15 years ago the great advantages of such archives. Recent studies by Alma Swan and others have shown that a very large proportion of scientists are not aware of open access and therefore what we need is focused advocacy. Even among those who know of OA, many are not depositing their papers in archives but say they would if they are asked by their bosses or their funding agencies. Clearly the ball is in the court of scientists and policy makers. OA is especially advantageous to the developing countries as the current access to literatures is poorest in these countries. 相似文献

The creation of electronic collections is changing the nature of libraries. Until recently an electronic collection meant providing an on-line public access catalog and a few CD-ROMs. Now the technologies exist to network CD-ROMs, load databases on Integrated Library Systems and access a number of commercial databases across the Internet for a fixed fee. With this responsibility comes a need to understand electronic information and options for its access. This article deals with three electronic information formats: CD-ROM, tape loads, and on-line hosts; reviews some of the hardware platforms used for accessing information in these formats; and, discusses some of the issues involved in interconnecting computer systems to increase access to electronic collections. 相似文献

Summary The contemporary academic library increasingly provides one or more public access computer labs. Students use these labs for word processing, Internet browsing, creating spreadsheets, and other related applications. Providing these types of computer labs in academic libraries is a relatively new development and requires effective management techniques. The purpose of this article is to examine some of the current management concepts, including background, funding, design and implementation, staffing, equipment, software, security and control, and patron relations. Effective management relies on a combination of physical and internal measures as well as a knowledgeable support staff. With the advancement of the Internet and other emerging technologies, the library must strive to maintain its position as a leader in the university environment. Providing computer labs is a valid response to the increasing demand by patrons for electronic resources. 相似文献
