    Abstract
    Ontologien werden eingesetzt, um durch semantische Fundierung insbesondere für das Dokumentenretrieval eine grundlegend bessere Basis zu haben, als dies gegenwärtiger Stand der Technik ist. Vorgestellt wird eine an der FH Darmstadt entwickelte und eingesetzte Ontologie, die den Gegenstandsbereich Hochschule sowohl breit abdecken und gleichzeitig differenziert semantisch beschreiben soll. Das Problem der semantischen Suche besteht nun darin, dass sie für Informationssuchende so einfach wie bei gängigen Suchmaschinen zu nutzen sein soll, und gleichzeitig auf der Grundlage des aufwendigen Informationsmodells hochwertige Ergebnisse liefern muss. Es wird beschrieben, welche Möglichkeiten die verwendete Software K-Infinity bereitstellt und mit welchem Konzept diese Möglichkeiten für eine semantische Suche nach Dokumenten und anderen Informationseinheiten (Personen, Veranstaltungen, Projekte etc.) eingesetzt werden.

    Abstract
    Informationsintegration auf Basis semantischer Modelle ist ein viel versprechender Ansatz zur Bewältigung des Informationsüberflusses. Informationen und Wissen stehen oft in großer Menge zur Verfügung, doch es ist sehr schwierig, das Wissen in einer spezifischen Situation zu fin-den oder überhaupt gewahr zu sein, dass adäquate Informationen vorhanden sind. Der Prozess des Suchens erfordert sehr viel Geduld und Erfahrung. Reine textuelle Suchmaschinen wie Google führen leider oft nicht oder nicht effizient genug zum Ziel. Eine zentrale Herausforderung ist daher die Filterung und strukturierte Aufbereitung von Informationen im Kontext der aktuellen Arbeitsumgebung und der jeweiligen Aufgabenstellung. Semantische Metadaten können dabei helfen, diese Abbildung vorhandener Informationsquellen in den Aufgabenkontext zu bewerkstelligen. Doch wie kommt man zu geeigneten, reichhaltigen semantischen Metadaten? Nach heutiger Praxis geschieht das hauptsächlich durch manuelle Verfahren, die allerdings auch viele Probleme aufwerfen. Daher ist der Erfolg semantischer Informationsintegration in hohem Maße davon abhängig, ob es gelingt semantische Metadaten automatisch zu extrahieren und hinreichend aktuell zu halten.

    Abstract
    Es werden Konzepte eines syntaktischen Metathesaurus, der identische Benennungen und deren Relationen aufeinander abbildet, vorgestellt und von semantischen Metathesauri abgegrenzt. Dieses aus mehreren Konzepten bestehende Modell bietet sich für die automatische Zusammenführung weit gehend übereinstimmender Thesauri zu einem virtuellen Metathesaurus an, den man in Internetportale und Suchmaschinen integrieren kann. Besondere Vorteile sind hierbei das günstige Kosten-Nutzen- Verhältnis und die geringen technischen Anforderungen eines syntaktischen Metathesaurus. Es werden die Inkonsistenzen bei der Zusammenführung inhomogener Thesauri ausführlich beschrieben und Möglichkeiten zur Konsistenzverbesserung angeboten. Ein syntaktisches Thesauruskonzept eignet sich für den Einsatz bei der Websuche in Parlamentsinformationssystemen, wie z. B. dem Parlamentsspiegel, einer Datenbank zum Nachweis der deutschen Parlamentsmaterialien.

    Abstract
    Despite the dissemination of modeling languages and tools for representation and construction of ontologies, their underlying methodologies can still be improved. As a consequence, ontology tools can be enhanced accordingly, in order to support users through the ontology construction process. This paper proposes suggestions for ontology tools' improvement based on a case study within the domain of bioinformatics, applying a reuse method ology. Quantitative and qualitative analyses were carried out on a subset of 28 terms of Gene Ontology on a semi-automatic alignment with other biomedical ontologies. As a result, a report is presented containing suggestions for enhancing ontology reuse tools, which is a product derived from difficulties that we had in reusing a set of OBO ontologies. For the reuse process, a set of steps closely related to those of Pinto and Martin's methodology was used. In each step, it was observed that the experiment would have been significantly improved if ontology manipulation tools had provided certain features. Accordingly, problematic aspects in ontology tools are presented and suggestions are made aiming at getting better results in ontology reuse.
