    Abstract
    Standardisierung und Normierung sind einer der Grundpfeiler traditioneller Inhaltserschließung von Bibliotheken und fachbezogenen Informationszentren. Metadaten-Aktivitäten wie die Dublin Core Initiative greifen diese grundsätzliche Vorgehensweise für das WWW in erneuerter Form auf. Sie bildet auch das Fundament des Paradigmas von "Publizieren im Web". Gleichzeitig gibt es aber klare Anzeichen dafür, dass die traditionellen Verfahren der Standardisierung und Normierung an ihre Grenzen stoßen. Für digitale Bibliotheken muss deshalb vor allem für die Inhaltserschließung eine neue Sichtweise auf die Forderung nach Konsistenzerhaltung und Interoperabilität gefunden werden. Sie lässt sich durch die folgende Prämisse umschreiben: Standardisierung ist von der verbleibenden Heterogenität her zu denken. Erst im gemeinsamen Zusammenwirken von intellektuellen und automatischen Verfahren zur Heterogenitätsbehandlung und denen einer neu verstandenen Standardisierung ergibt sich eine Lösungsstrategie, die den heutigen technischen und gesellschaftlichen Rahmenbedingungen gerecht wird.

    Abstract
    In this paper we present a multimodal design concept for a materials information system interface. The project WING-IIR combines both form-oriented and natural language database in a GUI-based environment, giving the user a choice of query modes. Our design is embedded in a tool-based, object oriented structure which allows for adequate interpretation and usability for both, novice and expert users. Implementing context-sensitivity and transparency between query modalities and different levels of data granularity further help in solving difficult materials problems. In addition a number of different Intelligent Information Retrieval (IIR) modules complement the basic database interface: a stereotype-based user model reduces interface complexity by adapting to the users' actual interests; the WING-GRAPH component allows for graphical retrieval of materials curves, i.e. users may manipulate graphical data representations in order to query the database and a fuzzy-WING component is proposed for modelling vagueness in natural language queries as well as for vague interpretation of seemingly exact queries

    Abstract
    Neben Crosskonkordanzen, qualitativ-deduktiven Methoden und statistischen Verfahren gehört zu den Grundstrategien der Behandlung semantischer Heterogenität auch der Einsatz neuronaler Netze in Transfermodulen zwischen Dokumentenbeständen mit unterschiedlichen Inhaltserschließungssystemen. Sowohl die Frage, welches Netzwerkmodell am erfolgsversprechendsten ist, als auch die Frage, ob neuronale Netze im Kontext integrierter Fachinformationssysteme in der Praxis einen Mehrwert erbringen können, ist bisher in der Forschung kaum behandelt worden. Deshalb wurde diese Thematik in einer Kooperation vom IZ mit der Universität Hildesheim im Rahmen eines Promotionsvorhabens (Mandl, T.) erforscht

    Abstract
    Users of scientific information are now faced with a highly decentralized, heterogeneous document base with varied content analysis methods. Traditional providers of information such as libraries or information centers have been increasingly joined by scientists themselves, who are developing independent services of varying scope, relevance and type of development in the WWW. Theoretically, groups that have gathered current research information (CRI), literature or factual information an specialized subjects can emerge anywhere in the world. One consequence of this is the presence of various inconsistencies: - Relevant, quality-controlled data can be found right next to irrelevant and perhaps demonstrably erroneous data. - In a system of this kind, descriptor A can assume the most disparate meanings. Even in the narrower context of specialized information, descriptor A, which has been extracted in an intellectually and qualitatively correct manner, and with much Gare and attention, from a highly relevant document, is not to be compared with a term A that has been provided by automatic indexing in some peripheral area. Thus, the main problem to be solved is as follows: users must be supplied with heterogeneous data from different sources, modalities and content analysis processes via a visual user interface without inconsistencies in content analysis, for example, seriously impairing the quality of the search results. A scientist who, for example, is looking for social science information an subject X does not first want to search the social science literature database SOLIS and the current research database FORIS, and then the library catalogues of the special compilation area of social sciences at the library catalogues and in the WWW - each time using different search strategies. He wants to phrase his search query only once in the terminology to which he is accustomed without dealing with the remaining problems. Closer analysis of this problems Shows that narrow technological concepts, even if they are undoubtedly necessary, are not sufficient an their own. They must be supplemented by new conceptual considerations relating to the treatment of breaks in consistency between the different processes of content analysis. Acceptable solutions are only obtained when both aspects are combined. The IZ research group (Bonn, Germany) is working an this aspect in four different projects: Carmen, ViBSoz, ELVIRA and the ETB project. Initial solutions for transfer modules are available now and will be discussed.

    Abstract
    As an important support tool in science research, specialized information systems are rapidly changing their character. The potential for improvement compared with today's usual systems is enormous. This fact will be demonstrated by means of two problem complexes: - WWW search engines, which were developed without any government grants, are increasingly dominating the scene. Does the WWW displace information centers with their high quality databases? What are the results we can get nowadays using general WWW search engines? - In addition to the WWW and specialized databases, scientists now use WWW library catalogues of digital libraries, which combine the catalogues from an entire region or a country. At the same time, however, they are faced with highly decentralized heterogeneous databases which contain the widest range of textual sources and data, e.g. from surveys. One consequence is the presence of serious inconsistencies in quality, relevance and content analysis. Thus, the main problem to be solved is as follows: users must be supplied with heterogeneous data from different sources, modalities and content development processes via a visual user interface without inconsistencies in content development, for example, seriously impairing the quality of the search results, e. g. when phrasing their search inquiry in the terminology to which they are accustomed

    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
    Die Informationswissenschaft, die sich am klarsten über ihren Informationsbegriff von ihren Nachbardisziplinen absetzt, ist ausgehend von der Zeit ihrer fruchtbarsten Definitionsphase in den siebziger und achtziger Jahren eng mit den Sozialwissenschaften verbunden. Welches ihr Anteil an der Informationswissenschaft ist, und - umgekehrt - wie der Informationsbegriff und die damit verbundenen Problemstellungen sich in den heutigen Sozialwissenschaften-vor allem in der Soziologie -widerspiegeln, das soll im Folgenden geklärt werden. Wersig dient hierbei als Ausgangspunkt. Er behandelte mit seiner Informationssoziologie vor dreißig Jahren - wenn auch sehr zeitbezogen-bis heute gültige Weichenstellungen. Für eine Sicht aus dem Blickwinkel der Soziologie bietet sich die Diskussion um die Informationsgesellschaft an, die mit Castells den bisher klarsten theoretisch-methodischen Ausdruck fand. Im Kern geht es bei diesen Fragen immer um den "praktischsten" und ertragreichsten Blickwinkel auf die Gestaltung von Informationssystemen und deren Folgen für uns alle, die wir die Gesellschaft im soziologischen Sinn bilden. Es geht aber auch um wissenschaftsorganisatorische Ansprüche und Abgrenzungen. Gegenüber der technischen und informationstheoretischen Sicht auf Information verwenden Informationswissenschaftler kommunikative Vorgänge als Ausgangspunkt einer Begriffsklärung (von Daten, Information, Wissen) und definieren für Information einen "pragmatischen Primat", um für ihren zentralen Begriff einen eigenständigen Ansatz als Leitprinzip der Forschung zu gewinnen. Information im Sinne der Informationswissenschaft entsteht erst benutzerseitig in einer spezifischen Anwendungssituation (vgl. Kap. A 1). Kuhlen, auf den die programmatische Formel "Information ist Wissen in Aktion" zurückgeht, weist darauf hin, dass die Informationswissenschaft "claims to reflect upon the use of information in social environments". Er will "people make sensitive to the fact that information is, above and beyond its technical or computational aspects, a social phenomenon". Aber was genau soll das bedeuten, vor allem für die praktische Entwicklungs- und Forschungsarbeit? Wo hört die Informationswissenschaft auf und wo beginnen die Sozialwissenschaften, speziell die Soziologie? Wie lassen sich ihre fachspezifischen Sichtweisen der Informationsgesellschaft aufeinander beziehen?

    Abstract
    The middle of the 1990s are coined by the increased enthusiasm for the possibilities of the WWW, which has only recently deviated - at least in relation to scientific information - for the differentiated measuring of its advantages and disadvantages. Web Information Retrieval originated as a specialized discipline with great commercial significance (for an overview see Lewandowski 2005). Besides the new technological structure that enables the indexing and searching (in seconds) of unimaginable amounts of data worldwide, new assessment processes for the ranking of search results are being developed, which use the link structures of the Web. They are the main innovation with respect to the traditional "mother discipline" of Information Retrieval. From the beginning, link structures of Web pages are applied to commercial search engines in a wide array of variations. From the perspective of scientific information, link topology based approaches were in essence trying to solve a self-created problem: on the one hand, it quickly became clear that the openness of the Web led to an up-tonow unknown increase in available information, but this also caused the quality of the Web pages searched to become a problem - and with it the relevance of the results. The gatekeeper function of traditional information providers, which narrows down every user query to focus on high-quality sources was lacking. Therefore, the recognition of the "authoritativeness" of the Web pages by general search engines such as Google was one of the most important factors for their success.

    Abstract
    Bei der Diskussion um Standardisierungsbemühungen in den Bibliotheken, Archiven, den Fachdatenbanken und den Informationen auf WWW-Servern wissenschaftlicher Institute gibt es klare Anzeichen dafür, dass die traditionellen Verfahren der Standardisierung und Normierung an ihre Grenzen stoßen. Für Virtuelle Fachbibliotheken muss deshalb vor allem für die Inhaltserschließung eine neue Sichtweise auf die Forderung nach Konsistenzerhaltung und Interoperabilität gefunden werden. Sie lässt sich durch die folgende Prämisse umschreiben: Standardisierung ist von der verbleibenden Heterogenität her zu denken. Erst im gemeinsamen Zusammenwirken von intellektuellen und automatischen Verfahren zur Heterogenitätsbehandlung und Standardisierung ergibt sich eine Lösungsstrategie, die den heutigen technischen und gesellschaftlichen Rahmenbedingungen gerecht wird.

    Abstract
    Der Arbeitsbericht konzentriert sich zunächst auf Integrationsmöglichkeiten des Dreiländerkatalogs (DLK), der prototypisch für fachübergreifende Bibliothekskataloge (Allgemeinzugang) in vascoda steht. Der Bericht geht auf interne Designvarianten ein, welche Grundüberlegungen zum sogenannten Allgemeinzugang bebildern. Abschnitt 2 befasst sich mit Vorschlägen zur Erweiterung der Suchtypologie von vascoda. Eine Änderung der fachgebietsorientierten Grundkonzeption von vascoda lässt sich weder aus der Literatursichtung noch aus der vascoda-internen Diskussion anlässlich der Contentintegration von DLK und der Einführung der FAST-Suchmaschinentechnologie für vascoda-Teilmengen ableiten.
