    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
    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
    Die Entwicklungsperspektive für den Bereich wissenschaftlicher Information sind innovative, integrierende Fachportale, die in einem Wissenschaftsportal zusammengefasst werden und die allgemeinen, fachübergreifenden Zugänge der Bibliotheken mit spezifischen Fachzugängen verbinden. In dieser Struktur kann der Kunde mit qualitativ hochwertigen Such- und Selektionsinstrumenten auf wissenschaftsrelevante Informationen (Literaturnachweise, Experten und Forschungsreferenzen, Volltexte, Materialien, Daten, Fakten, Linklisten etc.) zugreifen. Sowohl theoriegeleitete Analysen und Bestandsaufnahmen der wissenschaftlichen Informationslandschaft als auch die Ergebnisse der neueren Benutzerumfragen zum Informationsverhalten und zum -bedarf von Wissenschaftlern weisen auf die Wünschbarkeit solch einer Entwicklung hin. Heute ist ein weitgehender Konsens über das anzustrebende Ziel erreicht. Die Herausforderung für die Weiterentwicklung ist somit nicht die Akzeptanz der angestrebten Zielvorstellung, sondern die Frage, wie sie zu erreichen ist. Die im Folgenden diskutierte Entwicklung von bilateralen Transferkomponenten zur Behandlung semantischer Heterogenität zwischen Dokumentensammlungen mit unterschiedlicher Inhaltserschließung zeigt für einen wesentlichen Teil der Frage nach dem »Wie« der Zielerreichung eine tragfähige Lösungsstrategie auf. Sie wird theoretisch und praktisch konkretisiert, der Entwicklungsstand beschrieben und die konkreten Einsatzmöglichkeiten werden aufgezeigt.
