Naming and Addressing Conventions for Digital Resources

This paper discusses the various naming and addressing systems used to identify and locate resources in the digital environment. there are various schemes that have been developed for this purpose, like, URL, URN, URC schemes developed by the IETF (Internet Engineering Task Force), PURL developed at OCLC. The publishing industry also has developed the Digital Object Identifier (DOI), which is being used for rights management of intellectual property. The specifications and the working of URLs, URNs, URCs, PURLs, and DOIs are discussed in detail in this paper

Identification Schemes for Digital Resources

This paper discusses the various naming and addressing systems used to identify and locate resources in the digital environment. There are various schemes that have been developed for this purpose, like, URL, URN, URC schemes developed by the IETF (Internet Engineering Task Force), PURL developed at OCLC. The publishing industry also has developed the Digital Object Identifier (DOI), which is being used for rights management of intellectual property. The specifications and the working of URLs, URNs, PURLs, Handles and DOIs are discussed in detail in this paper

Beyond Web 2.0... And Beyond the Semantic Web

International audienceInitiated by Manuel Zacklad in 2003, the 'Socio-semantic Web' has recently seen important developments. Contrary to the Semantic Web, it is not interested in formal semantics but in semantics dependent on the human subject and on the semiotic substrate. Moreover, it aims at fostering people participation in knowledge work, such as Web 2.0 does for entertainment. In this trend, software design relies on three human and social phenomena: • documents, because they are proofs of something else, not in the manner of a mathematical proof but more in line of evidence that is kept and that can be mobilized; • interpretation, because the meaning of a document depends on its authors and readers; • intersubjectivity, because the confrontation between conflicting interpretations allows to overcome subjectivity. We illustrate our definition and design approach with descriptions of a course-material sharing platform and of a software enabling collaborative analysis

Handling Information Overload on Usenet : Advanced Caching Methods for News

Usenet is the name of a world wide network of servers for group communication between people. From 1979 and onwards, it has seen a near exponential growth in the amount of data transported, which has been a strain on bandwidth and storage. There has been a wide range of academic research with focus on the WWW, but Usenet has been neglected. Instead, Usenet's evolution has been dominated by practical solutions. This thesis describes the history of Usenet in a growth perspective, and introduces methods for collection and analysis of statistical data for testing the usefulness of various caching strategies. A set of different caching strategies are proposed and examined in light of bandwidth and storage demands as well as user perceived performance. I have shown that advanced caching methods for news offers relief for reading servers' storage and bandwidth capacity by exploiting usage patterns for fetching or pre\-fetching articles the users may want to read, but it will not solve the problem of near exponential growth nor the problems of Usenet's backbone peers

NewsView: A Recommender System for Usenet based on FAST Data Search

This thesis combines aspects from two approaches to information access, information filtering and information retrieval, in an effort to improve the signal to noise ratio in interfaces to conversational data. These two ideas are blended into one system by augmenting a search engine indexing Usenet messages with concepts and ideas from recommender systems theory. My aim is to achieve a situation where the overall result relevance is improved by exploiting the qualities of both approaches. Important issues in this context are obtaining ratings, evaluating relevance rankings and the application of useful user profiles. An architecture called NewsView has been designed as part of the work on this thesis. NewsView describes a framework for interfaces to Usenet with information retrieval and information filtering concepts built into it, as well as extensive navigational possibilities within the data. My aim with this framework is to provide a testbed for user interface, information filtering and information retrieval issues, and, most importantly, combinations of the three

Development of Online Course System and an Open Access Online Repository

This Project was divided in to two phases: the first phase comprising of development of an online course system for the institute with the help of moodle. Moodle( modular object oriented dynamic learning environment) is an open source software package for producing internet-based courses and web sites. It's an ongoing development project designed to support a social Constructionist framework of education. Moodle is provided freely as Open Source software (under the GNU Public License). Basically this means Moodle is copyrighted, but that we have additional freedoms of improvising the source code. The 2nd Phase of the project was that of deployment of an open access online repository system using E-prints. EPrints is an open source software package for building open access repositories that are compliant with the Open Archives Initiative Protocol for Metadata Harvesting. It shares many of the features commonly seen in Document Management systems, but is primarily used for institutional repositories and scientific journals. EPrints has been developed at the University of Southampton School of Electronics and Computer Science and released under a GPL license

Just-in-time hypermedia

Many analytical applications, especially legacy systems, create documents and display screens in response to user queries dynamically or in real time . These documents and displays do not exist in advance, and thus hypermedia must be generated \u27just in time -automatically and dynamically. This dissertation details the idea of \u27just-in-time hypermedia and discusses challenges encountered in this research area. A fully detailed literature review about the research issues and related research work is given. A framework for the \u27just-in-time hypermedia compares virtual documents with static documents, as well as dynamic with static hypermedia functionality. Conceptual \u27just-in-time hypermedia architecture is proposed in terms of requirements and logical components. The \u27just-in-time hypermedia engine is described in terms of architecture, functional components, information flow, and implementation details. Then test results are described and evaluated. Lastly, contributions, limitations, and future work are discussed
