James Duff Brown (1862-1914), an important figure in librarianship in late nineteenth and early twentieth century England, made contributions in many areas of his chosen field. His Subject Classification (SC), however, has not received much recognition for its theoretical and practical contributions to bibliographic classification theory and practice in the twentieth century. This paper discusses some of the elements of SC that both did and did not inform future bibliographic classification work, considers some contrasting evaluation methods in the light of advances in bibliographic classification theory and practice and of commentaries on SC, and suggests directions for further research.

This paper provides a summary of the initial development of a Web portal for the digital government domain. Information retrieval techniques commonly used to find information on the Internet are discussed along with the problems associated with these techniques that led to the development of the Digital Government Web portal (DGPort). We also discuss the advantages that DGPort could have for researchers in the digital government domain as well as the value-added features that this portal provides. Future evaluation plans for the portal are also described.

There has been renewed research interest in using the statistical approach to extraction of key phrases from Chinese documents because existing approaches do not allow online frequency updates after phrases have been extracted. This consequently results in inaccurate, partial extraction. In this paper, we present an updateable PAT-tree approach. In our experiment, we compared our approach with that of Lee-Feng Chien with that showed an improvement in recall from 0.19 to 0.43 and in precision from 0.52 to 0.70. This paper also reviews the requirements for a data structure that facilitates implementation of any statistical approaches to key-phrase extraction, including PATtree, PAT-array and suffix array with semi-infinite strings.

The paper discusses the concept of intellectual repository (IR) its need, importance,benefits, critical issues, major problems in establishment & maintenance of IR, role of librarians, intellectual society, academic institutions and the government. It also gives an overview of Intellectual Repository (IR) initiatives taken in the institutions of higher learning in Indian scenario.

The teaching of authority control in schools of library and information science is alive and well, even though it is not perceived this way by some former students. Many professors are fervently attempting to imbue the next generation of librarians with an understanding of the necessity for authority control. Unfortunately, they have to fight the nonunderstanding of colleagues, the lack of course time to be as thorough as desired, and the perception that information technology is uppermost in importance among courses to be taught. However, because the chaotic environment of the Web has brought attention to the need for authority control (e.g., the "semantic web"), we have a new opportunity to teach these concepts to a new generation of information professionals.

Presentation given by Hsinchun Chen at the NASA Meeting during PMSEP3 on the future of knowledge management. The presentation describes research performed by the Artificial Intelligence Lab at the University of Arizona to create a Perpetual Self-Organizing (PSO) approach to knowledge management funded by NSF, DARPA, NASA, NIJ, and NIH.

The purpose of this paper is to examine the displays and exhibitions in university libraries. It was conducted by questionnaire survey on six theses: Frequency and purpose, Staffing, Funding, Space and safeguards, Subjects, materials and sources, and Marketing. The results reveal that most libraries held displays and exhibitions and thought displays and exhibitions as marketing and educational ser-vices to patrons. But supporting resources such as staffing, funding, space, security, and facilities were informal and scant. To improve the displays and exhibitions, this paper suggests that libraries should pay more resources and concerns on displays and exhibitions to achieve the marketing and educational goal. Besides, librarians play important roles in displays and exhibitions. To plan a professional and successful displays and exhibitions, librarians need more support on training, display knowledge and credits.

This paper reports the results of PhD research into the future needs of library professionals for educa-tion in the digital era with special consideration to the needs of the Hong Kong Special Administrative Region (SAR), Peoples Republic of China (PRC). The research method used was a Delphi study and representatives from China, Taiwan, Hong Kong, Macau, Singapore and the United States were chosen as participants in the study. This paper outlines the special features of this method and why it was se-lected, how it was implemented and initial findings from the study. The research attempted to identify an ideal curriculum especially for use in the Hong Kong SAR, China, but also for consideration in other areas of South East Asia. It was conducted using the Delphi technique which is based upon the premise that a decision made by a group is more reliable and thus more desirable than a decision made by an individual.

Areas related to nanotechnology, or nanoscale science and engineering (NSSE), have experienced tremendous growth over the past few years. While there are a large variety of useful resources available on the Web, such information are usually distributed and difficult to locate, resulting in the problem of information overload. To address the problem, we developed the NanoPort system, an integrated Web portal aiming to provide a one-stop shopping service to satisfy the information needs of researchers and practitioners in the field of NSSE [1]. We believe that the approaches taken also can be applied to other domains.

Education for library profession is a revolutionary process. The core of the curricula is the people in relation to the information itself and technology that enable the provision of this information. There is a need to produce library science graduates with sophisticated management and policy and planning skills and the vision to translate core values of today and tomorrowâ s information world. Due to the ongoing developments in information technology sector, the information professionals trained in the latest information handling techniques would also become obsolete after a short time. Hence, the curricula must be reviewed constantly to determine whether the changes are in tune with the present and future job requirements.
