    Abstract
    Der Wissensnavigator ist ein Lexikon der Zukunft auf dem Weg zu einer interaktiven Enzyklopädie. Wenn Sie die elektronische Fassung online benutzen, können Sie von den einzelnen Artikeln über Hyperlinks zu Seiten im World Wide Web gelangen, die noch mehr Informationen zum jeweiligen Zukunftsbegriff enthalten. Bei der elektronischen Ausgabe des Wissensnavigators, die auch im Internet zugänglich ist handelt es sich um eine "lebende" Anwendung, die sich gerade auch durch die Mitwirkung der Nutzer weiterentwickelt. Sie sind herzlich eingeladen, zum Teilnehmer dieses Evolutionsprozesses zu werden - etwa, indem Sie neue Begriffe vorschlagen, die aufgenommen werden sollen, oder Experten benennen, die zur Bearbeitung neuer Begriffe in Frage kommen, oder auch sich selbst als Experte zu erkennen geben. Eine Redaktion, die aus dem Autor und einem Expertenteam im Verlag besteht, wird über die Aufnahme neuer Begriffe entscheiden

    Abstract
    With the recent rapid diffusion over the international computer networks of world-wide distributed document bases, the question of multilingual access and multilingual information retrieval is becoming increasingly relevant. We briefly discuss just some of the issues that must be addressed in order to implement a multilingual interface for a Digital Library system and describe our own approach to this problem.

    Abstract
    Information retrieval over the Internet increasingly requires the filtering of thousands of heterogeneous information sources. Important sources of information include not only traditional databases with structured data and queries, but also increasing numbers of non-traditional, semi- or unstructured collections such as Web sites, FTP archives, etc. As the number and variability of sources increases, new ways of automatically summarizing, discovering, and selecting collections relevant to a user's query are needed. One such method involves the use of classification schemes, such as the Library of Congress Classification (LCC), within which a collection may be represented based on its content, irrespective of the structure of the actual data or documents. For such a system to be useful in a large-scale distributed environment, it must be easy to use for both collection managers and users. As a result, it must be possible to classify documents automatically within a classification scheme. Furthermore, there must be a straightforward and intuitive interface with which the user may use the scheme to assist in information retrieval (IR). Our work with the Alexandria Digital Library (ADL) Project focuses on geo-referenced information, whether text, maps, aerial photographs, or satellite images. As a result, we have emphasized techniques which work with both text and non-text, such as combined textual and graphical queries, multi-dimensional indexing, and IR methods which are not solely dependent on words or phrases. Part of this work involves locating relevant online sources of information. In particular, we have designed and are currently testing aspects of an architecture, Pharos, which we believe will scale up to 1.000.000 heterogeneous sources. Pharos accommodates heterogeneity in content and format, both among multiple sources as well as within a single source. That is, we consider sources to include Web sites, FTP archives, newsgroups, and full digital libraries; all of these systems can include a wide variety of content and multimedia data formats. Pharos is based on the use of hierarchical classification schemes. These include not only well-known 'subject' (or 'concept') based schemes such as the Dewey Decimal System and the LCC, but also, for example, geographic classifications, which might be constructed as layers of smaller and smaller hierarchical longitude/latitude boxes. Pharos is designed to work with sophisticated queries which utilize subjects, geographical locations, temporal specifications, and other types of information domains. The Pharos architecture requires that hierarchically structured collection metadata be extracted so that it can be partitioned in such a way as to greatly enhance scalability. Automated classification is important to Pharos because it allows information sources to extract the requisite collection metadata automatically that must be distributed.

    Abstract
    The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Currently, both practice and theory point at linking services as being a major domain for innovation enabled by digital communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information. This is the first of two articles in D-Lib Magazine on this topic. This first part describes the current state-of-the-art and contrasts various approaches to the problem. It identifies static and dynamic linking solutions as well as open and closed linking frameworks. It also includes an extensive bibliography. The second part, SFX, a Generic Linking Solution describes a system that we have developed for linking in a hybrid working environment. The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Although most writings on electronic scientific communication have touted other benefits, such as the increase in communication speed, the possibility to exchange multimedia content and the absence of limitations on the length of research papers, currently both practice and theory point at linking services as being a major opportunity for improved communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added-value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information.

    Abstract
    The concept for the German Digital Libraries Program is imbedded in the Information Infrastructure Program of the German Federal Government for the years 1996-2000 which has been explicated in the Program Paper entitled "Information as Raw Material for Innovation".3 The Program Paper was published 1996 by the Federal Ministry for Education, Research, and Technology. The actual grants program "Global Info" was initiated by the Information and Communication Commission of the Joint Learned Societies to further technological advancement in enabling all researchers in Germany direct access to literature, research results, and other relevant information. This Commission was founded by four of the learned societies in 1995, and it has sponsored a series of workshops to increase awareness of leading edge technology and innovations in accessing electronic information sources. Now, nine of the leading research-level learned societies -- often those with umbrella responsibilities for other learned societies in their field -- are members of the Information and Communication Commission and represent the mathematicians, physicists, computer scientists, chemists, educational researchers, sociologists, psychologists, biologists and information technologists in the German Association of Engineers. (The German professional librarian societies are not members, as such, of this Commission, but are represented through delegates from libraries in the learned societies and in the future, hopefully, also by the German Association of Documentalists or through the cooperation between the documentalist and librarian professional societies.) The Federal Ministry earmarked 60 Million German Marks for projects within the framework of the German Digital Libraries Program in two phases over the next six years. The scope for the German Digital Libraries Program was announced in a press release in April 1997,4 and the first call for preliminary projects and expressions of interest in participation ended in July 1997. The Consortium members were suggested by the Information and Communication Commission of the Learned Societies (IuK Kommission), by key scientific research funding agencies in the German government, and by the publishers themselves. The first official meeting of the participants took place on December 1, 1997, at the Deutsche Bibliothek, located in the renowned center of German book trade, Frankfurt, thus documenting the active role and participation of libraries and publishers. In contrast to the Digital Libraries Project of the National Science Foundation in the United States, the German Digital Libraries project is based on furthering cooperation with universities, scientific publishing houses (including various international publishers), book dealers, and special subject information centers, as well as academic and research libraries. The goals of the German Digital Libraries Project are to achieve: 1) efficient access to world wide information; 2) directly from the scientist's desktop; 3) while providing the organization for and stimulating fundamental structural changes in the information and communication process of the scientific community.

    Abstract
    Information retrieval over the Internet increasingly requires the filtering of thousands of heterogeneous information sources. Important sources of information include not only traditional databases with structured data and queries, but also increasing numbers of non-traditional, semi- or unstructured collections such as Web sites, FTP archives, etc. As the number and variability of sources increases, new ways of automatically summarizing, discovering, and selecting collections relevant to a user's query are needed. One such method involves the use of classification schemes, such as the Library of Congress Classification (LCC) [10], within which a collection may be represented based on its content, irrespective of the structure of the actual data or documents. For such a system to be useful in a large-scale distributed environment, it must be easy to use for both collection managers and users. As a result, it must be possible to classify documents automatically within a classification scheme. Furthermore, there must be a straightforward and intuitive interface with which the user may use the scheme to assist in information retrieval (IR).

    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
    Der gegenwärtige Wandel zur Informationsgesellschaft betrifft auch die Bibliotheken. Schlagworte wie "virtuelle Bibliothek" oder "digitale Bibliothek" tauchen immer häufiger in der Bibliothekslandschaft auf. Die Bücher-Bibliotheken" werden nicht verschwinden, aber sie müssen sich der Herausforderung der Informationsgesellschaft stellen und ihre Rolle neu definieren. Wissenschaftliche Bibliotheken nehmen sich bereits seit einiger Zeit der neuen Informations- und Kommunikationstechnologien an, aber auch für die Öffentlichen Bibliotheken besteht Handlungsbedarf. Das Land Salzburg hat deshalb eine Studie mit dem Titel "Die Digitale Bibliothek" bei der Techno-Z Fachhochschule Forschung und Entwicklung GmbH in Auftrag gegeben, die Strategien für die Weiterentwicklung der Öffentlichen Bibliotheken des Landes im Informationszeitalter entwickeln soll. Die Ergebnisse dieser Studie sind nicht nur für die Öffentlichen Bibliotheken im Land Salzburg von Interesse, sondern betreffen auch andere Regionen und deren Bibliothekslandschaft. Aufgrund der großen Nachfrage haben wir uns daher zu einem Sonderdruck des Heftes 15 der "Materialien zur Weiterbildung in Salzburg" mit den wichtigsten Ergebnisse der Studie entschlossen. So liegt neben dem umfangreichen Endbericht eine Kurzfassung vor. Diese Kurzfassung haben wir für Sie via Internet zugänglich gemacht.

    Abstract
    Zu den großen Herausforderungen einer sinnvollen Suche im WWW gehören die riesige Menge des Verfügbaren und die Sparchbarrieren. Verfahren, die die Web-Ressourcen im Hinblick auf ein effizienteres Retrieval inhaltlich strukturieren, werden daher ebenso dringend benötigt wie Programme, die mit der Sprachvielfalt umgehen können. Im folgenden Vortrag werden wir einige Ansätze diskutieren, die zur Bewältigung der beiden Probleme derzeit unternommen werden
