    Abstract
    Unternehmen sehen sich heutzutage regelmäßig der Herausforderung gegenübergestellt, aus umfangreichen Mengen an Dokumenten schnell relevante Informationen zu identifizieren. Dabei zeigt sich jedoch, dass Suchverfahren, die lediglich syntaktische Abgleiche von Informationsbedarfen mit potenziell relevanten Dokumenten durchführen, häufig nicht die an sie gestellten Erwartungen erfüllen. Viel versprechendes Potenzial bietet hier der Einsatz von Ontologien für das Information Retrieval. Beim ontologiebasierten Information Retrieval werden Ontologien eingesetzt, um Wissen in einer Form abzubilden, die durch Informationssysteme verarbeitet werden kann. Eine Berücksichtigung des so explizierten Wissens durch Suchalgorithmen führt dann zu einer optimierten Deckung von Informationsbedarfen. Jan Hermans stellt in seinem Buch ein adaptives Referenzmodell für die Entwicklung von ontologiebasierten Information Retrieval-Systemen vor. Zentrales Element seines Modells ist die einsatzkontextspezifische Adaption des Retrievalprozesses durch bewährte Techniken, die ausgewählte Aspekte des ontologiebasierten Information Retrievals bereits effektiv und effizient unterstützen. Die Anwendung des Referenzmodells wird anhand eines Fallbeispiels illustriert, bei dem ein Information Retrieval-System für die Suche nach Open Source-Komponenten entwickelt wird. Das Buch richtet sich gleichermaßen an Dozenten und Studierende der Wirtschaftsinformatik, Informatik und Betriebswirtschaftslehre sowie an Praktiker, die die Informationssuche im Unternehmen verbessern möchten. Jan Hermans, Jahrgang 1978, studierte Wirtschaftsinformatik an der Westfälischen Wilhelms-Universität in Münster. Seit 2003 war er als Wissenschaftlicher Mitarbeiter am European Research Center for Information Systems der WWU Münster tätig. Seine Forschungsschwerpunkte lagen in den Bereichen Wissensmanagement und Information Retrieval. Im Mai 2008 erfolgte seine Promotion zum Doktor der Wirtschaftswissenschaften.

    Abstract
    Webbasierte Informationssysteme werden heute von einer Vielzahl unterschiedlicher Organisationen angeboten, mit ganz verschiedenen Zielsetzungen. Die technischen Herausforderungen bzgl. Datenhaltung, Pflege der Informationen und Anbindung an das Internet scheinen gelöst. Das Auffinden bestimmter Informationen stellt für viele Nutzer aber dennoch eine große Herausforderung dar. Das gilt für das WWW (WorldWide Web ) als Ganzes, wie auch für viele einzelne webbasierte Informationssysteme. Grund dafür sind im Wesentlichen die nach wie vor ungenügenden Benutzungs-schnittstellen. Heutig gängige webbasierte Informationssysteme bieten Nutzern meist neben einer Navigation die Möglichkeit, Informationen durch das Absenden einer Suchanfrage zu suchen. Beide Strategien, also die Suche und die Navigation, weisen jeweils eigene Probleme in der Umsetzung auf, die es verhindern, dass Nutzer die gewünschte Information einfach auffinden können. Oftmals werden Suchanfragen unspezifisch und allgemein gehalten vorgetragen. Wird eine solche Anfrage mit einer großen Zusammenstellung von Daten beantwortet, man denke nur an Suchergebnisse von Suchmaschinen mit tausenden Treffern, und damit tausenden von Nieten, kann sich schnell Frust einstellen. Aber auch heutige Navigationen sind nicht geeignet, es dem Nutzer so einfach wie möglich zu machen. Sie beschränken sich meist auf Begriffshierarchien. Der Informationsraum wird also in Ober- und Unterklassen gegliedert und die Informationsobjekte den Ebenen zugeordnet. Eine solche Aufteilung kann für den einen sinnvoll und verständlich sein, andere aber in die Irre führen. Zudem lassen sich Begriffe nur anhand zweier Beziehungen, nämlich Ober- und Unterbegriff, strukturieren. Begriffe und Konzepte vieler Themengebiete weisen aber weitere Beziehungen auf, wie "gehört zu", "arbeitet zusammen mit", "entwickelte" um nur ein paar Beispiele zu nennen. Semantische Netze bzw. Ontologien können eine solche Verknüpfung durch die Beschreibung ebendieser Beziehungen leisten. Die Ausgangsüberlegung dieser Arbeit ist es, die Strukturierung des Informationsraums mit Hilfe einer Ontologie vorzunehmen. Diese erweiterte Strukturierung soll sowohl für die Suche als auch für die Navigation genutzt werden, um die Auffindbarkeit von Information zu verbessern. Eine Suchfunktionalität müsste sich nicht mehr nur auf eine wortbasierte Suche verlassen, sondern könnte das Beziehungsgeflecht nutzen. Die Navigation wiederum könnte die Beziehungen explizit machen und dadurch Nutzern helfen, den Informationsraum zu verstehen und dadurch einfacher zielgerichtet zu der gewünschten Information zu navigieren. Als Untersuchungsgegenstand werden in dieser Arbeit Bürgerinformationssysteme betrachtet. Die Anwendungsdomäne webbasierte Bürgerinformation ist ausreichend komplex, um daran die oben angeführten Probleme untersuchen zu können. Heutige Bürgerinformationssysteme weisen, neben anderen Problemen, genau die oben beschriebenen Schwächen auf, wie sich zeigen wird.

    Content
    The paper describes current work on the generation of a thesaurus format from the schedules of the Bliss Bibliographic Classification 2nd edition (BC2). The practical problems that occur in moving from a concept based approach to a terminological approach cluster around issues of vocabulary control that are not fully addressed in a systematic structure. These difficulties can be exacerbated within domains in the humanities because large numbers of culture specific terms may need to be accommodated in any thesaurus. The ways in which these problems can be resolved within the context of a semi-automated approach to the thesaurus generation have consequences for the management of classification data in the source vocabulary. The way in which the vocabulary is marked up for the purpose of machine manipulation is described, and some of the implications for editorial policy are discussed and examples given. The value of the classification notation as a language independent representation and mapping tool should not be sacrificed in such an exercise.

    Abstract
    Facet analysis is proposed as a general theory of knowledge organization, with an associated methodology that may be applied to the development of terminology tools in a variety of contexts and formats. Faceted classifications originated as a means of representing complexity in semantic content that facilitates logical organization and effective retrieval in a physical environment. This is achieved through meticulous analysis of concepts, their structural and functional status (based on fundamental categories), and their inter-relationships. These features provide an excellent basis for the general conceptual modelling of domains, and for the generation of KOS other than systematic classifications. This is demonstrated by the adoption of a faceted approach to many web search and visualization tools, and by the emergence of a facet based methodology for the construction of thesauri. Current work on the Bliss Bibliographic Classification (Second Edition) is investigating the ways in which the full complexity of faceted structures may be represented through encoded data, capable of generating intellectually and mechanically compatible forms of indexing tools from a single source. It is suggested that a number of research questions relating to the Semantic Web could be tackled through the medium of facet analysis.
