- Abstract
- Das WWW ist dumm. Ein neuer Ansatz soll jetzt dafür sorgen, dass Maschinen Bedeutungen erfassen und Informationen richtig einordnen können. Das ist noch nicht alles: Wenn die Server erst mal das Verstehen gelernt haben sollten, würden sie auch in der Lage sein, uns von den Ergebnissen ihrer Plaudereien untereinander zu berichten - das 'semantische Web' wäre geboren

- Abstract
- The ever growing popularity of the Internet as a source of information, coupled with the accompanying growth in the number of documents made available through the World Wide Web, is leading to an increasing demand for more efficient and accurate information retrieval tools. Numerous techniques have been proposed and tried for improving the effectiveness of searching the World Wide Web for documents relevant to a given topic of interest. The specification of appropriate keywords and phrases by the user is crucial for the successful execution of a query as measured by the relevance of documents retrieved. Lack of users' knowledge an the search topic and their changing information needs often make it difficult for them to find suitable keywords or phrases for a query. This results in searches that fail to cover all likely aspects of the topic of interest. We describe a scheme that attempts to remedy this situation by automatically expanding the user query through the analysis of initially retrieved documents. Experimental results to demonstrate the effectiveness of the query expansion scheure are presented.

- Abstract
- Dieser Beitrag beschäftigt sich mit INSYDER, einem visuell unterstützten Suchsystem im Umfeld der sogenannten Business Intelligence Systeme. Dabei liegt der Schwerpunkt dieses Beitrags in der Erläuterung der Information Retrieval- und Visualisierungsaspekte zur Unterstützung des Suchprozesses im WWW. Vorgestellt wird das Rankingverfahren, das Interaktive Relevance Feedback sowie die Beschreibung der Unterstützung des Benutzers bei der Formulierung der Suchanfrage mittels Visualisierung.
- Content
- This paper presents a visual information seeking system for the WWW called INSYDER. The aim of INSYDER is to find business information from the WWW. Information seeking - especially on the Web - is an imprecise process. Information seekers often have only a fuzzy understanding of how they can get the information they want. This paper focuses on the use of information retrieval and visualisation techniques of the INSYDER system to support the user in extracting information from the WWW, namely in formulating queries, refining and reviewing results

- Abstract
- Die Anpassung der deutschen Gesetzgebung an europäische Vorgaben wie die elektronische Signatur und die sich dramatisch verändernde Situation im Umfeld der digitalen Kommunikation hat auch für die elektronische Archivierung weitreichende Folgen. Die Grundlagen für neue Anforderungen zur Archivierung digitaler Geschäftsunterlagen finden sich bereits in den Änderungen von HGB AO, die im Zuge der Steuerreform im Jahr 2000 verabschiedet wurden. Hierzu wurde quasi als Ausführungsbestimmung die GDPdU geschaffen, in der die Verwendung der elektronischen Signatur verankert und der Zugriff der Finanzbehörden auf Datenbestände in den Unternehmen konkretisiert ist.

- Abstract
- Describes the origins of the CATaloguing and Retrieval of Information Over Network Applications (CATRIONA) Study in the BUBL Subject Tree service and nots its aims: to investigate the requirements for developing procedures and applications for cataloguing and retrieval of networked resources (particularly via the Internet); and to explore the feasibility of a collaborative project to develop and integrate them with existing library systems. The project established that a distributed catalogue of networked resources integrated with standard Z39.50 library system OPAC interfaces with information on hard copy resources is already a practical proposition at a basic level. Notes that at least one Z30.50 OPAC client can searcg remote Z39.50 OPACs, retrieve USMARC records with URLs in MARC field 856

- Abstract
- This book constitutes the refereed proceedings of the 7th European Conference on Research and Advanced Technology for Digital Libraries, ECDL 2003, held in Trondheim, Norway in August 2003. The 39 revised full papers and 8 revised short papers presented were carefully reviewed and selected from 161 submissions. The papers are organized in topical sections on uses, users, and user interfaces; metadata applications; annotation and recommendation; automatic classification and indexing; Web technologies; topical crawling and subject gateways; architectures and systems; knowledge organization; collection building and management; information retrieval; digital preservation; and indexing and searching of special documents and collection information.

- Abstract
- Die sich rasant verändernde Informationslandschaft erfordert ein Umdenken in den verschiedenen Informations- und Dokumentationsstellen; es gibt kaum noch einen Arbeitsbereich, der nicht stetigen Umwälzungen unterworfen ist. Besonders in der Auskunftstätigkeit sehen wir uns mit neuen Herausforderungen konfrontiert, um der zunehmenden Disintermediation zu begegnen. Unseren Kunden stehen übers Internet vielfältige Wege zur Verfügung, um sich die Informationen selbst zu beschaffen, was jedoch meist dazu führt, dass sie sich in den Weiten des World Wide Web verlieren. Die Kompetenz und sachkundige Navigationshilfe der Informations- und Dokumentationsspezialisten wird demnach je länger, umso mehr gefordert sein; es verändert sich lediglich die Art und Weise des Auskunftgebens: ,Librarians need to more formally incorporate this awesome information power into a new model of service provision so that they may position themselves to meet the needs of reference services in the next century". Vor diesem Hintergrund drängt sich nicht nur ein anderes Vorgehen beim Kundeninterview auf, sondern es stellt sich ebenfalls die Frage, wie man die Informations- und Kommunikationstechnologien (l+K-Technologien) sinnvoll einsetzen kann, sowohl für den konventionellen als auch für den virtuellen Auskunftsdienst. Das zunehmende Aufkommen virtueller Universitäten verlangt nach neuen innovativen Ideen, um den potenziellen Studenten angemessene Dienstleistungen zu bieten, die es ihnen erlauben, das ganze Spektrum der l+K-Technologien voll auszuschöpfen. Virtuelle Auskunftsdienste bzw. "virtual reference desks" sind immer häufiger beliebte Themen in der Fachpresse und werden in Zukunft als entscheidender Wettbewerbsfaktor gelten. Wie kann man die vorhandenen Informationen so bündeln und kanalisieren, dass unsere Kunden so rasch und so effizient als möglich zu den von ihnen nachgefragten Inhalten kommen? Ein kurzer Überblick über den heutigen Entwicklungsstand der "virtual reference desks" zeigt auf, dass vor allem die "Internet Public Library" (IPL) auf diesem Gebiet Pionierarbeit geleistet hat, dass ihre Angebote jedoch nicht über E-Mail-Auskunft hinausgehen. Anhand eines dreistufigen Auskunftsmodells werden fortschrittliche Möglichkeiten aufgezeigt, wie man Fernauskunft unter Einbezug aller Internetdienste (E-Mail, Newsgroups, Chat, WWW) abwickeln und gestalten könnte, wobei vor allem technische Ansätze berücksichtigt werden, das ganze Umfeld einer virtuellen Universität jedoch nicht außer Acht gelassen wird.

- Abstract
- 'Internet in Öffentlichen Bibliotheken' lautete der Titel eines Materialienbandes, den das Deutsche Bibliotheksinstitut bereits im letzen Jahr herausgegeben hatte - zu Grundlagen in den Bereichen Markt, Recht, Technik und zur Praxis mit Berichten von Konzepten und Erfahrungen. Daß dieser Band auch in seiner Themenfülle und -vielfalt nicht alles Aspekte dieses komplexen neuen Mediums würde aufgreifen können, und daß auch mit der rasanten Weiterentwicklung des Mediums das Thema damit noch keinesfalls 'abgehakt' sein würde, kristallisierte sich schon zu dem Zeitpunkt seiner Entstehung heraus. Eine Fortsetzung, Vertiefung und Erweiterung also war dringend geboten und wird hier vorgelegt - freilich ohne die Illusion, damit alle Aspekte gar erschöpfend behandeln zu können, wohl aber in der Hoffnung, einige Arbeits- und Orientierungshilfen in den wichtigsten Bereichen zu geben
