Using DDC to create a visual knowledge map as an aid to online information retrieval

Selection of search terms in an online search environment can be facilitated by the visual display of a knowledge map showing the various concepts and their links. This paper reports on a preliminary research aimed at designing a prototype knowledge map using DDC and its visual display. The prototype knowledge map created using the Protæ#169;gæ#169; and TGViz freeware has been demonstrated, and further areas of research in this field are discussed

Access and usability issues of scholarly electronic publications

This chapter looks at the various access and usability issues related to scholarly information resources. It first looks at the various channels through which a user can get access to scholarly electronic publications. It then discusses the issues and studies surrounding usability. Some important parameters for measuring the usability of information access systems have been identified. Finally the chapter looks at the major problems facing the users in getting access to scholarly information through today's hybrid libraries, and mentions some possible measures to resolve these problems

Knowledge organization or information organization : a key component of knowledge management activities

This paper focuses on the various bibliographic and information retrieval tools and techniques used for information organization, a key activity in a knowledge management process. The paper begins with the existing debate on the very concept of knowledge management, and looks at some recent papers and arguments on this issue. It then briefly discusses how some projects over the past decade or so have used various traditional bibliographic organization tools for providing access to electronic resources. This follows examples of some sophistical information organization techniques used by some speciality search engines. It is argued that these tools and techniques, although are quite useful, cannot be used as such in a knowledge management environment. A generic model of information access in a knowledge management environment is then proposed, and new areas of research, especially in the context of information organization are discussed

How to make best use of the intellectual output of a country? a simple approach to the design of a digital library of theses and dissertations in Indian universities

In India there are hundreds of universities and other academic institutions catering for the needs of millions of users. INFLIBNET is in an excellent position to spearhead in building such digital libraries, and in this paper I would like to propose some simple guidelines for this

Access to information in digital libraries : users and digital divide

Recognising the importance of information and knowledge in all spheres of human life, the recently held World Summit on Information Society came up with a plan of action for building a global information society. The goal of the world information society initiatives is the same as that of digital library research and development - to make information and knowledge accessibleto everyone in the world. Digital libraries have progressed very rapidly over the past ten or soyears. This paper addresses the two most important aspects of the information society - information users and digital divide. Findings of some large-scale studies on human information behaviour on the web and digital libraries have been discussed. The major findings of a study on access to electronic resources by university students are the presented. Proposed that a one-stop window approach with a task-based information organisation and access system may be the way forward

Digital reference services : a snapshot of the current practices in scottish libraries

Discusses the current practices followed by some major libraries in Scotland for providing digital reference services(DRS). Refers to the DRSs provided by three academic libraries, namely Glasgow University Library, the University of Strathclyde Library, and Glasgow Caledonian University Library, and two other premier libraries in Scotland, the Mitchell Library in Glasgow and the National Library of Scotland in Edinburgh. Concludes that digital reference services are effective forms of service delivery in Scotland's academic, national and public libraries, but that their full potential has not yet been exploited. E-mail is the major technology used in providing digital reference, although plans are under way to use more sophisticated Internet technologies. Notes that the majority of enquiries handled by the libraries are relatively low-level rather than concerning specific knowledge domains, and training the users to extract information from the best digital resources still remains a challenge

Firewalls in AdS/CFT

Several recent papers argue against firewalls by relaxing the requirement for locality outside the stretched horizon. In the firewall argument, locality essentially serves the purpose of ensuring that the degrees of freedom required for infall are those in the proximity of the black hole and not the ones in the early radiation. We make the firewall argument sharper by utilizing the AdS/CFT framework and claim that the firewall argument essentially states that the dual to a thermal state in the CFT is a firewall.Comment: 11 pages plus references, 8 figures; version accepted for publication in JHE
