    Abstract
    Menschliches Wissen und menschliche Sprache sind aufeinander bezogen und voneinander abhängig. Dies gilt auch und gerade bei den Bemühungen, Sprache und Wissen computergestützt so zu verarbeiten, dass für Menschen nutzbare maschinelle Wissensverarbeitung stattfindet. Jenseits von eher akademischen "Laborversuchen" hat wissenschaftliche Forschungsarbeit auf diesem Gebiet die Verfügbarkeit umfangreicher, gepflegter und sauber codierter Wissensbasen sowohl der verwendeten Sprache als auch des abgebildeten Gegenstands zur Voraussetzung. In einem Forschungsprojekt der Firma Brockhaus Duden Neue Medien GmbH gemeinsam mit namhaften wissenschaftlichen Partnern, u.a. dem Fraunhofer-IPSI, dem IICM der TU Graz, dem IAI der Universität Saarbrücken und dem KNOW-Center, Graz, wurde diese Herausforderung erfolgreich angegangen. Für eine neue digitale Brockhaus-Auflage wurden Informationsrepräsentations- und Retrievaltechniken entwickelt, die nicht auf domänenspezifischen Beschränkungen beruhend den gesamten enzyklopädischen Wissenskreis abdecken. Die entwickelten Formalismen erwiesen sich nicht nur zur Abfrage des enzyklopädischen Wissens in natürlicher Sprache als geeignet, sondern konnten auch darauf basierend neuartige Formen der Visualisierung von Wissenszusammenhängen implementiert werden. Die Ergebnisse zeigen zum einen Möglichkeiten erfolgreichen semantischen Retrievals ohne extensiven Einsatzformaler Metacodierungen, zum anderen weisen sie den Weg und die nächsten Schritte bei der Entwicklung noch leistungsfähigerer Mensch-Maschine-Schnittstellen.

    Abstract
    Cognitive Maps sind mentale Karten, welche jeder Mensch besitzt. Es handelt sich dabei um eine Reflexion der jeweiligen Umwelt. Cognitive Mapping ist eine Methode, welche diese mentale Karte sichtbar macht. Aufgrund dieser Visualisierung können Erkenntnisse darüber gewonnen werden, was Menschen an einem Ort oder in einem Raum tun und wahrnehmen. Die Methode hat verschiede Anwendungstechniken, welche sich in sechs Kategorien teilen: Aufgabenlösung, Elemente orten, Sketch Map erstellen, Zonen und Gebiete einzeichnen, Weg- und Ortsbeschreibung sowie Kognitive Befragung. Anhand dieser lassen sich Untersuchungen beliebig kombinieren. Die Anwendung von Cognitive Mapping sowie eine einfache Befragung in der Kantonsbibliothek Graubünden hat ergeben, dass die Methode für Bibliotheken sinnvoll ist. Allerdings sollte bei zukünftigen Anwendungen die Punkte Gesamtaufwand, Untersuchungsaufbau, Teilnehmer-Zusammensetzung und Auswertungs-Aufwand angepasst werden.

    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.
