    Abstract
    Final report of a British Library supported conducted at University College, London, computer science department, the aim of which was to build a demonstration and test bed facility for online access to a large electronic library of multimedia documents. The project was a pilot experiment in the use of a database of compound documents (text and images) in the Open Document Architecture format. The database used is part of the contents of information in the Journal of the American Chemical Society. Discusses the overall view of the project with particular reference to the WAIS information retrieval server which was developed and used

    Abstract
    Presents the findings of the South Ayrshire Libraries OPen Learning and the Internet project, Sep 1997 to Oct 1998. The objective was to demonstrate how open learning materials available on the Internet could be integrated with the provision of local open learning resources to provide an enhanced learning environment in public libraries. The main areas of concentration within the project were information skills support to public library users and the provision of WWW based independent materials to learners. The organisation and retrieval of Web based resources for local use was a major issue throughout the project. Recommends the adoption of Dublin Core metadata standards, the connection of databases of resources with searchable wen pages, and the development of thesauri of terms used to index the Web based resources locally. Sstaff training, and the new skills which will need to be developed, were identified as issues. Cost was also identified as a related issue, extending to issues such as access to open learning material and the Internet

    Abstract
    The aim of the CATRIONA (Cataloguing and Retrieval of Information over Networks Applications) feasibility study was to investigate the technical, organizational and financial requirements for the development of applications software and procedures to enable the cataloguing, calssification and retrieval of documents and other resources over networks such as the Internet. The CATRIONA feasibility study demonstrated that the idea of a distributed catalogue of Internet resources integrated with standard Z39.50 library system OPAC interfaces is already a practical proposition at its most basic level. Proposes that the next step should be a distributed CATRIONA demonstrator project, based on the Scottish University and Research Libraries (SCURL) group of libraries cooperating to catalogue local electronic resources and selected areas of BUBL Subject Trees, but also sufficiently 'open' to encompass other sites, projects and approaches

    Abstract
    Over the past 50 years, a variety of language-related capabilities has been developed in machine translation, information retrieval, speech recognition, text summarization, and so on. These applications rest upon a set of core techniques such as language modeling, information extraction, parsing, generation, and multimedia planning and integration; and they involve methods using statistics, rules, grammars, lexicons, ontologies, training techniques, and so on. It is a puzzling fact that although all of this work deals with language in some form or other, the major applications have each developed a separate research field. For example, there is no reason why speech recognition techniques involving n-grams and hidden Markov models could not have been used in machine translation 15 years earlier than they were, or why some of the lexical and semantic insights from the subarea called Computational Linguistics are still not used in information retrieval.
    This picture will rapidly change. The twin challenges of massive information overload via the web and ubiquitous computers present us with an unavoidable task: developing techniques to handle multilingual and multi-modal information robustly and efficiently, with as high quality performance as possible. The most effective way for us to address such a mammoth task, and to ensure that our various techniques and applications fit together, is to start talking across the artificial research boundaries. Extending the current technologies will require integrating the various capabilities into multi-functional and multi-lingual natural language systems. However, at this time there is no clear vision of how these technologies could or should be assembled into a coherent framework. What would be involved in connecting a speech recognition system to an information retrieval engine, and then using machine translation and summarization software to process the retrieved text? How can traditional parsing and generation be enhanced with statistical techniques? What would be the effect of carefully crafted lexicons on traditional information retrieval? At which points should machine translation be interleaved within information retrieval systems to enable multilingual processing?

    Abstract
    In der folgenden Studie wird eine Komponente für eine visuelle Benutzerschnittstelle zu Textdatenbanken entworfen. Mit Hilfe einer Terminologievisualisierung wird dem Benutzer eine Hilfestellung bei der Relevanzbewertung von Dokumenten und bei der Erweiterung seiner visuellen Anfrage an das Retrieval-System gegeben. Dazu werden zuerst die grundlegenden Information-Retrieval-Modelle eingehender vorgestellt, d.h., generelle Retrieval-Modelle, Retrievaloperationen und spezielle Retrieval-Modelle wie Text-Retrieval werden erläutert. Die Funktionalität eines Text-Retrieval-Systems wird vorgestellt. Darüber hinaus werden bereits existierende Implementierungen visueller Information-Retrieval-Benutzerschnittstellen vorgestellt. Im weiteren Verlauf der Arbeit werden mögliche Visualisierungen der mit Hilfe eines Text-Retrieval-Systems gefundenen Dokumente aufgezeigt. Es werden mehrere Vorschläge zur Visualisierung von Thesauri diskutiert. Es wird gezeigt, wie neuronale Netze zur Kartierung eines Eingabebereiches benutzt werden können. Klassifikationsebenen einer objekt-orientierten Annäherung eines Information-Retrieval-Systems werden vorgestellt. In diesem Zusammenhang werden auch die Eigenschaften von Thesauri sowie die Architektur und Funktion eines Parsersystems erläutert. Mit diesen Voraussetzung wird die Implementierung einer visuellen Terminologierunterstützung realisiert. Abschließend wird ein Fazit zur vorgestellten Realisierung basierend auf einem Drei-Schichten-Modell von [Agosti et al. 1990] gezogen.

    Abstract
    Reports results of a study, prompted by a number of questions which have been raised about the extent to which the DOI meets, or can be developed to meet, the real requirements of the marketplace for a unique identifier of digital content. Develops a series of scenarios to explore future ways in which digital information may be accessed and used and considers the role of unique identification of content in each of them. The business models, selected for the scenarios, must represent to some extent a subjective forecast of what the future might look like. Their purpose is to attempt to illuminate some generic aspects of unique identification that appear likely to be important in future

    Abstract
    Describes the final phase of the work on the ELINOR (Electronic Library INformation Online Retrieval) project at De Montfort University, Leicester, which concluded in 1996. ELINOR was 2 phase project with 3 overall goals: to create a practical pilot system based on a commercial product (Excalibur EFS); to investigate the expansion of a small scale electronic library to a larger, distributed library system; and to develop a more efficient and effective means of accessing and sharing resources within a networked multi campus institution. ELINOR was successful in demonstrating that libraries may conveniently digitize and supply smal collections of high demand materials over a campus network in text anf TIFF format. Operational conditions have so far indicated that the barriers are not technological but involve copyright, use issues and sustainability

    Abstract
    Reviews the basic techniques involving genetic algorithms and their application to 2 problems in information retrieval: the generation of equifrequent groups of index terms; and the identification of optimal query and term weights. The algorithm developed for the generation of equifrequent groupings proved to be effective in operation, achieving results comparable with those obtained using a good deterministic algorithm. The algorithm developed for the identification of optimal query and term weighting involves fitness function that is based on full relevance information

    Abstract
    Im Jahr 1995 entstand in interdisziplinärer Zusammenarbeit der Prototyp Bücherschatz, ein Bibliotheks-Online_katalog für Kinder. Beteiligt waren Studierende und eine Professorin der FH Hamburg, Fb Bibliothek und Information, ein Designer und 2 Informatikerinnen der Universität Hamburg. In diesem Bericht werden sowohl das Produkt Bücherschatz als auch der Prozeß seiner Entwicklung beschrieben. Ein Schwerpunkt liegt in der Auseinandersetzung mit theoretischen Modellen der Softwaretechnik - hier STEPS und Prototyping - und ihrer Anpassung an konkrete Projekterfordernisse. Weiterhin werden Fragen nach der Gestaltung kindgerechter Software, der Organisation eines großen Projektteams und nach der Art der Partizipation der Benutzer thematisiert. Das Gesamtprojekt wird in einen wissenschaftlichen Kontext der Informatik eingeordnet, und zentrale Erfahrungen und Erkenntnisse hinsichtlich interdisziplinärer und partizipativer Softwareentwicklung werden zusammengefaßt
