- Abstract
- View based searching and multi view searching using HIBROWSE proposes a new paradigm for information retrieval from bibliographic databases and database management systems. The paradigm replaces command line and form based interaction with query specification and interaction which requires the user to identify views relating to query facets of the subject of their query. Attempted to apply techniques from human-computer interaction design in the development, construction and usability evaluation of a view based searching system for a very large bibliographic database. As the development of the HIBROWSE system had been in progress before usability became a major concern, as well as the class of system being developed, greater progress towards improved usability was made by adopting a less structured development life-cycle. Examined the usefulness of a number of usability evaluation methods in the context of trying to determine the usability of designs in interactive information retrieval systems. Measurement of the subjective usability of prototypes reinforced the finding of users' difficulties in forming a useful account of the system behaviour and functionality from the training material provided, highlighted some aspects of the system that could be improved, and the greater usability of the HIBROWSE prototypes over an extant commercial bibliographic database system

- Abstract
- Describes work of the BOPAC2 project, funded by the British Library Research and Inoovation Centre, from Sep 1996 to Jan 1997, to investigate the issues involved in managing large and complex retrievals involving Z39.50 searches, including searches of multiple databases. The system is a WWW front end that allows simultaneously access to a number of library OPACs via Z39.50. The system is designed to make access to large and complex retrieval simpler, similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. Describes the design, development and evaluation of the system with suggestions for future work

- Abstract
- Die rasanten Veränderungen der Kommunikation und der daraus resultierende soziale und kulturelle Wandel betreffen auch die Hochschulen in besonderer Weise. Hochschulleitungen haben hier bereits schon reagiert, sie stehen aber weiterhin vor der Herausforderung, auf die Veränderungen zu reagieren und entsprechende Maßnahmen zu ergreifen. Es bedarf nicht nur einer Harmonisierung des Informationsmanagements und der Informationsinfrastruktur, sondern integrativ auch der Stärkung der Informationskompetenz auf allen Ebenen der Organisation. Da diese Herausforderung das gesamte System Hochschule betrifft, wird der Begriff der Informationskompetenz hier gegenüber seiner herkömmlichen Verwendung deutlich ausgeweitet: Es wird nicht nur die akademische Informationskompetenz betrachtet, die in Lehre und Forschung zum Tragen kommt, sondern auch die organisationsbezogene Informationskompetenz, die sich auf alle hochschulinternen Abläufe bezieht. Zugleich geht es in der Empfehlung nicht, wie es der Titelbegriff "Hochschule im digitalen Zeitalter" nahe legen könnte, um Konzepte wie das einer Netzhochschule.

- Abstract
- Reports on the findings of the major study, carried out by the Royal Society, etc. and prompted by the concern felt about the increasing signs of strain in the scientific, technical and medical information systems (STM) and the consequences for technical research. The report is a follow up to the earlier study (BLRDD report 5626) with the aim of covering the trends which have developed since the earlier report was published (online information retrieval, electronic networks, CD-ROM etc.). The study covers: the nature of the UK scientific, technical and medical information system; users of the STM information system; the changing role of libraries and librarians with regard to periodicals, books and other services; economic aspects of the STM information system (research libraries, primary publishing, secondary publishing, and value of scientific research); economic aspects of the STM information system, and perceived problems and potential changes with regard to primary periodicals, electronic periodicals, user interaction, and funding of the services. The data derived from the user survey and the library survey are published in full with analysis. Presents the conclusions and recommendations arising from the study

- Abstract
- Seit Bestehen der Menschheit sammelt der Mensch Informationen, seit Bestehen des Internets stellt der Mensch Informationen ins Web, seit Bestehen des Semantic Webs sollen auch Maschinen in die Lage versetzt werden mit diesen Informationen umzugehen. Das Bibliothekswesen ist einer der Sammler. Seit Jahrhunderten werden Kataloge und Bibliografien sowie Inventarnachweise geführt. Mit der Aufgabe des Zettelkatalogs hin zum Onlinekatalog wurde es Benutzern plötzlich möglich in Beständen komfortabel zu suchen. Durch die Bereitstellung von Daten aus dem Bibliothekswesen im Semantic Web sollen nicht nur die eigenen Katalogsysteme Zugriff auf diese Informationen erhalten, sondern jede beliebige Anwendung, die auf das Web zugreifen kann. Darüber hinaus ist die Vorstellung, dass sich die im Web befindenden Daten - in sofern möglich - miteinander verlinken und zu einem gigantischen semantischen Netz werden, das als ein großer Datenpool verwendet werden kann. Die Voraussetzung hierfür ist wie beim Übergang zum Onlinekatalog die Aufbereitung der Daten in einem passenden Format. Normdaten dienen im Bibliothekswesen bereits dazu eine Vernetzung der unterschiedlichen Bestände zu erlauben. Bei der Erschließung eines Buches wird nicht bloß gesagt, dass jemand, der Thomas Mann heißt, der Autor ist - es wird eine Verknüpfung vom Katalogisat zu dem Thomas Mann erzeugt, der am 6. Juni 1875 in Lübeck geboren und am 12. August 1955 in Zürich verstorben ist. Der Vorteil von Normdateneintragungen ist, dass sie zum eindeutigen Nachweis der Verfasserschaft oder Mitwirkung an einem Werk beitragen. Auch stehen Normdateneintragungen bereits allen Bibliotheken für die Nachnutzung bereit - der Schritt ins Semantic Web wäre somit die Öffnung der Normdaten für alle denkbaren Nutzergruppen.

- Abstract
- Nowadays, users of information services are faced with highly decentralised, heterogeneous document sources with different content analysis. Semantic heterogeneity occurs e.g. when resources using different systems for content description are searched using a simple query system. This report describes several approaches of handling semantic heterogeneity used in projects of the German Social Science Information Centre

- 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
- In einem Benutzertest, der im Rahmen der Projektes GIRT stattfand, wurde die Leistungsfähigkeit zweier Retrievalsprachen für die Datenbankrecherche überprüft. Die Ergebnisse werden in diesem Bericht dargestellt: Das System FULCRUM beruht auf automatischer Indexierung und liefert ein nach statistischer Relevanz sortiertes Suchergebnis. Die Standardfreitextsuche des Systems MESSENGER wurde um die intellektuell vom IZ vergebenen Deskriptoren ergänzt. Die Ergebnisse zeigen, dass in FULCRUM das Boole'sche Exakt-Match-Retrieval dem Verktos-Space-Modell (Best-Match-Verfahren) von den Versuchspersonen vorgezogen wurde. Die in MESSENGER realisierte Mischform aus intellektueller und automatischer Indexierung erwies sich gegenüber dem quantitativ-statistischen Ansatz beim Recall als überlegen

- 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
- State of the art review of hypertext systems in use in UK libraries. Systems include public access point of information (POI) systems that provide guidance to users of local resources, and networked document retrieval systems, such as WWW, that enable users to access texts stored on machines linked by the Internet. Particular emphasis is placed on those systems that are produced inhouse by the libraries in which they are used. The review is based on a series of telephone or face to face interviews conducted with representatives of those organizations that a literature review and mailed questionnaire survey identified as current users of hypertext. Considers issues relating to system development and usability, and presents a set of appropriate guidelines for the designers of future systems. Concludes that: the principle application of hypertext systems in UK libraries is in the implementation of POI systems; that such development is most advanced in the academic sector; and that such development is set to increase in tandem with use of the WWW

- Abstract
- "Enzyklopädie im Wandel: Schmuckstück der Bücherwand, rotierende Scheibe oder Netzangebot?" lautete das Thema der Auftaktveranstaltung, die am 12. Dezember 2001 im Rahmen des Diskussionsforums "Kölner Dialog Informationswissenschaft" an der Fachhochschule Köln stattfand. Enzyklopädien sind stets dem Zeitgeist verpflichtet und im Wandel begriffen. Sie passen sich in ihrer Konzeption den zu erwartenden Bedürfnissen der Benutzer und den produktionstechnischen Möglichkeiten an. Gegenwärtig ist ein Nebeneinander von gedruckten und digitalen Enzyklopädien zu beobachten. Während gedruckte Enzyklopädien die Breite des Wissens zweidimensional erfahrbar machen und für den raschen Zugriff oft weiterhin bevorzugt werden, bieten Enzyklopädien in digitaler Form neben neuen Retrievaltechniken durch multimediale Synergien einen erheblich verbesserten Zugang zu den erläuterten Phänomenen. Die Autoren dieses Bandes setzen sich mit den Ansprüchen auseinander, die an die Konzeption von Enzyklopädien zu Beginn des 21. Jahrhunderts gestellt werden. Die einzelnen Beiträge vermitteln einen Einblick in Entstehung, Umfang und Funktionalitäten der auf der Buchmesse 2001 vorgestellten Neuausgaben der renommierten Nachschlagewerke "Brockhaus multimedial" und "Microsoft Encarta". Abschließend werden die Fragenkomplexe "Beitrag der Enzyklopädie zum Wissenserwerb heute" sowie "Entwicklungsperspektiven und Trägermedien von Enzyklopädien" thematisiert.
