Web-course search engine : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University

The World Wide Web is an amazing place that people's lives more and more rely on. Especially, for the young generation, they spend a significant amount of their play and study time using the Internet. Many tools have been developed to help the educational users in finding educational resources. These tools include various search engines. Web directories and educational domain gateways. Nevertheless, these systems have many weaknesses that made them unsuitable for the specific search needs of the learners. The research presented in this thesis describes the development of the Web-course search engine, which is a friendly, efficient and accurate helper for the learners to get what they want in the vast Internet ocean. The most attractive feature of this system is that the system uses one universal language, which lets the searchers and the resources "communicate" with each other. Then the learner searchers can find the Web-based educational resources that are most fit to their needs and course providers can provide all necessary information about their courseware. This universal language is one widely acceptable Metadata standard. Following the Metadata standard, the system collects exact information about educational resources, provides adequate search parameters for search and returns evaluative results. By using the Web-course search engine, the learners and the other educational users are able to find useful, valuable and related educational resources more effectively and efficiently. Some improvement suggestions of the search mechanism in the World Wide Web have been brought forward for the future research as a result of this project

RePEc and S-WoPEc: Internet access to electronic preprints in Economics

The first electronic Economics preprint appeared in 1993. Since then the growth has been dramatic as the use of the World Wide Web has exploded. RePEc has been instrumental in facilitating access to Economics preprints and in bringing order to the chaos that the WWW frequently represents. In a related effort S-WoPEc provides user friendly tools for adding data to the RePEc system. While this is significant in itself it has also been instrumental in fulfilling S-WoPEc's second goal--to provide increased exposure to Swedish Economics research

A Study on the Open Source Digital Library Software's: Special Reference to DSpace, EPrints and Greenstone

The richness in knowledge has changed access methods for all stake holders in retrieving key knowledge and relevant information. This paper presents a study of three open source digital library management software used to assimilate and disseminate information to world audience. The methodology followed involves online survey and study of related software documentation and associated technical manuals.Comment: 9 Pages, 3 Figures, 1 Table, "Published with International Journal of Computer Applications (IJCA)

STARGATE : Static Repository Gateway and Toolkit. Final Project Report

STARGATE (Static Repository Gateway and Toolkit) was funded by the Joint Information Systems Committee (JISC) and is intended to demonstrate the ease of use of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) Static Repository technology, and the potential benefits offered to publishers in making their metadata available in this way This technology offers a simpler method of participating in many information discovery services than creating fully-fledged OAI-compliant repositories. It does this by allowing the infrastructure and technical support required to participate in OAI-based services to be shifted from the data provider (the journal) to a third party and allows a single third party gateway provider to provide intermediation for many data providers (journals). Specifically, STARGATE has created a series of Static Repositories of publisher metadata provided by a selection of Library and Information Science journals. It has demonstrated the interoperability of these repositories by exposing their metadata via a Static Repository Gateway for harvesting and cross-searching by external service providers. The project has conducted a critical evaluation of the Static Repository approach in conjunction with the participating publishers and service providers. The technology works. The project has demonstrated that Static Repositories are easy to create and that the differences between fully-fledged and static OAI Repositories have no impact on the participation of small journal publishers in OAI-based services. The problems for a service that arise out of the use of Static Repositories are parallel to those created by any other repository dealing with journal articles. Problems arise from the diversity of metadata element sets provided by a given journal and the lack of specific metadata elements for the articles' volume and issue details. Another issue for the use of publishers' metadata arise as the collection policies of some existing services only allow Open Access materials to be included in them. The project recommends that the use of Static Repositories continues to be explored - in particular as a flexible way to expose existing sets of structured information to OAI services and to create the opportunity to enhance the metadata as part of the process. The project further recommends that the publishing community consider the creation or adoption of an application profile for journal articles to support information discovery that can search by volume and issue. Significant further use of the Static Repository technology by small journal publishers will require the future creation and maintenance of a community-specific Static Repository Gateway. Further use will also require advocacy within the publishing community but might initially be most effectively kick-started through the creation of OAI repositories based on metadata held by the commercial services which publish or mediate access to electronic copies of journals on behalf of small publishers

Servicing the federation : the case for metadata harvesting

The paper presents a comparative analysis of data harvesting and distributed computing as complementary models of service delivery within large-scale federated digital libraries. Informed by requirements of flexibility and scalability of federated services, the analysis focuses on the identification and assessment of model invariants. In particular, it abstracts over application domains, services, and protocol implementations. The analytical evidence produced shows that the harvesting model offers stronger guarantees of satisfying the identified requirements. In addition, it suggests a first characterisation of services based on their suitability to either model and thus indicates how they could be integrated in the context of a single federated digital library

Standards in Library Automation and Networking

The paper presented as a tutorial discusses the metadata and interoperability standards that a modern web-based library automation should be compliant with. It also emphasizes the need and reasons why Indian libraries should adopt such standards in their work and in planning and seeking both automation and networking solutions

Distributed resource discovery using a context sensitive infrastructure

Distributed Resource Discovery in a World Wide Web environment using full-text indices will never scale. The distinct properties of WWW information (volume, rate of change, topical diversity) limits the scaleability of traditional approaches to distributed Resource Discovery. An approach combining metadata clustering and query routing can, on the other hand, be proven to scale much better. This paper presents the Content-Sensitive Infrastructure, which is a design building on these results. We also present an analytical framework for comparing scaleability of different distribution strategies
