We propose a web page classification method for creating a high quality collection of researchers’ homepages. A method to reduce manual assessment required for assuring given precision/recall using a recall-assured and a precision-assured classifier is presented. Each classifier is built with SVM using textual features obtained from each page and its surrounding pages and tuning parameters. These pages are grouped based on connection types and relative URL hierarchy levels, and independent features are extracted from each group. Experiment results show the proposed features evidently improve classification performance and the manual assessment is significantly reduced.

Managing video data and providing semantic-based retrieval mechanism is an indispensable part of digital library. However, most exiting digital library systems only provide the functionality of retrieving video data by meta-data which can not fulfill users’ requirements. This is due to the lack of appropriate video semantic model and powerful query interface. In this paper, we will first briefly introduce our video semantic model SemTTE and its query language VSQL, then show how they can be implemented based on XML technologies and how strategies of mapping and optimization are chosen.

Ontology construction plays an important role in many semantically working environments, such as knowledge management systems and digital libraries. The efficiency, quality, and comprehensiveness of the construction process highly depends on the employed development framework. In this paper, we propose a Topic Maps-driven framework, called XRVAT, to alleviate the cumbersome construction procedure and generate both RDF/XTM ontologies with an effective XTM-to-RDF translation kernel. This paper briefly presents its design and an operational example.

The IIUM Library’s mission is to be an excellent information centre providing information to meet the learning, teaching, and research needs of its customers. The Library gives special attention to Islamic studies and its information resources are predominantly in English and Arabic. To make the resources readily accessible “anytime” and “anywhere” heavy investments were made in a digital library system that implements the latest ICT advancement. The need for Arabic language capabilities has always been one of the Library’s major requirements. This paper shares the Library’s experience in implementing a digital library system, focusing on the challenges in handling Arabic language information resources.

The paper presents an analysis of feedback taken from participants of trainers training programme of Council of Scientific and Industrial Research (CSIR), India, for 38 national R&D laboratories/institutions of CSIR. The study reveals the need of distribution and display of publicity material at prominent places of user institutions; training to end users requires repetitive and dynamic order; and library portal be the linking hub of all the information resources. The paper also covers web based monitoring and common search interface system developed for control and user friendliness.

In academic libraries, the digital library world has had a profound impact on staffing. Academic libraries are facing huge pressure on their staffing levels at a time when digital libraries are being introduced. Digital libraries cannot be divorced from ordinary libraries. What skills do traditional librarians need? There is little in the literature on training for staffing for digital libraries. Consequently, evidence from a recent PhD gleaned from research interviews of these digital libraries case studies is included in this paper. This research uncovered a variety of different management and organizational issues and revealed the large cost of personnel in the implementation and maintenance of digital libraries

This paper traces the history and developments in Open Archives Initiatives including open access journals, e-print archives and Institutional repositories. The setting up of NAL’s Institutional Repository using OSS GNU Eprints, document types with statistical analysis, country wise statistics of full text download, levels of accessibility and technologies used in building the Institutional Repository have been discussed at length.

There is a digital divide between developed and developing countries. The digital divide around the world is usually measured through statistical indices such as the number of telephone lines, personal computers, websites and Internet users and their ratio to the total population. This paper reviews scholarly published books, articles, newspapers, journals and conference proceedings that address the issues related to digital divide that is affecting so many citizens in developing countries especially in Bangladesh and the factors that alienate people from enjoying the benefits of ICT. The authors tried to discuss the overall situation and recommends possible strategies that can be implemented in developing countries to reverse the widening gap of digital divide.

CASDP is one of CALIS’s programs during the10th 5-year plan, it tries to build a group of subject databases characterized with China feature, local feature, high education feature or document resources feature, serving both teaching and research of high education and economic development. Since 2003, 75 subject databases from 61 universities have become members of the program. A Portal is being built to integrate all metadata and provide access to the whole world.

The National Diet Library (NDL) is Japan’s only national deposit library and also the country’s parliamentary library. Timed with the opening of the Kansai-kan of the NDL in 2002, it has expanded its electronic library services. The NDL has been actively working on digitization of its collections. The “Digital Library from the Meiji Era” (http://kindai.ndl.go.jp/), which was opened to the public in 2002, carries full-text digital images of about 127,000 volumes of 89,000 titles of the books published in the Meiji era (1868-1912). In addition, it has been promoting copyright clearance and digitization of most of the books published in the Taisho era (1912-1926). The NDL offers the “NDL Gallery” (http://www.ndl.go.jp/en/gallery/index. html) as an online exhibition under the general title “Memories of Japan,” on specific themes, and introduces unique materials held by the NDL with descriptions and commentaries. Nine exhibitions are available so far, including the “Birth of the Constitution of Japan” and “Portraits of Modern Japanese Historical Figures.” We will sequentially add new contents. The “Web Archiving Project (WARP)” (http://warp.ndl.go.jp/) is a project to preserve information gathered from the Internet for the sake of future generations. We have collected selected Internet resources with license agreements, and provided about 1,500 online periodicals and 1,900 websites. These services are available to anyone via the NDL’s website (http://www.ndl.go.jp/). Long-term digital preservation has become a significant issue. The NDL has conducted research on case examples of foreign countries and long-term preservation for packaged electronic publications since 2002. We will continue these studies to find practical application of migration and emulation. Based on the research results, the NDL has been working on construction of the NDL Digital Archive System which preserves and provides the digital information heritage of Japan for a long period. This system conforms to the Open Archival Information System (OAIS). We are also planning to construct a portal site for digital archives in Japan and are already providing the prototype (http://www.dap.ndl.go.jp/).
