    Abstract
    The term "facet" was introduced into the field of library classification systems by Ranganathan in the 1930's [Ranganathan, 1962]. A facet is a viewpoint or aspect. In contrast to traditional classification systems, faceted systems are modular in that a domain is analyzed in terms of baseline facets which are then synthesized. In this paper, the term "facet" is used in a broader meaning. Facets can describe different aspects on the same level of abstraction or the same aspect on different levels of abstraction. The notion of facets is related to database views, multicontexts and conceptual scaling in formal concept analysis [Ganter and Wille, 1999], polymorphism in object-oriented design, aspect-oriented programming, views and contexts in description logic and semantic networks. This paper presents a definition of facets in terms of faceted knowledge representation that incorporates the traditional narrower notion of facets and potentially facilitates translation between different knowledge representation formalisms. A goal of this approach is a modular, machine-aided knowledge base design mechanism. A possible application is faceted thesaurus construction for information retrieval and data mining. Reasoning complexity depends on the size of the modules (facets). A more general analysis of complexity will be left for future research.

    Abstract
    Semantische Netze unterstützen den Suchvorgang im Information Retrieval. Über ihre vielfältigen Relationen und Inferenzen unterstützen sie den Anwender und helfen Daten im Kontext zu präsentieren und zu erfassen. Die Relationen ermöglichen Suchanfragen die große Treffermengen produzieren zu verfeinern und so Treffermengen zu erreichen die möglichst genau das enthalten was gesucht wurde. Es wird, anhand eines Ausschnitts des Datenbestands des Haus der Geschichte der Bundesrepublik Deutschland in Bonn, aufgezeigt wie bestehende Datenbestände in semantische Netze überführt werden können und wie diese anschließend für das Retrieval eingesetzt werden können. Für die Modellierung des semantischen Netz wird die Open Source Software Protégé in den Versionen 3.4.4. und 4.1_beta eingesetzt, die Möglichkeiten des Retrieval werden anhand der Abfragesprachen DL Query und SPARQL sowie anhand der Software Ontology Browser und OntoGraf erläutert.

    Abstract
    Graphendatenbanken sind darauf optimiert, stark miteinander vernetzte Informationen effizient zu speichern und greifbar zu machen. Welchen Ansprüchen müssen Abfragesprachen genügen, damit sie für die Arbeit mit diesen Datenbanken geeignet sind? Bei der Aufarbeitung realer Informationen zeigt sich, dass ein hoher, aber unterschätzter Wert in den Beziehungen zwischen Elementen steckt. Seien es Ereignisse aus Geschichte und Politik, Personen in realen und virtuellen sozialen Netzen, Proteine und Gene, Abhängigkeiten in Märkten und Ökonomien oder Rechnernetze, Computer, Software und Anwender - alles ist miteinander verbunden. Der Graph ist ein Datenmodell, das solche Verbindungsgeflechte abbilden kann. Leider lässt sich das Modell mit relationalen und Aggregat-orientierten NoSQL-Datenbanken ab einer gewissen Komplexität jedoch schwer handhaben. Graphendatenbanken sind dagegen darauf optimiert, solche stark miteinander vernetzten Informationen effizient zu speichern und greifbar zu machen. Auch komplexe Fragen lassen sich durch ausgefeilte Abfragen schnell beantworten. Hierbei kommt es auf die geeignete Abfragesprache an.

    Abstract
    In dieser Arbeit wurde zuerst der Übergang von Suchmaschinen zu einem semantischen Web beschrieben. Im zweiten Kapitel wurden die Topic Maps ausführlicher behandelt. Angefangen bei der Geschichte von Topic Maps, über die Entwurfsziele bis hin zu einem XTM-Tutorial . In diesem Tutorial wurden verschiedene Beispiele durchgeführt und die Lineare Topic Map von Ontopia vorgestellt. Abschließend wurde anhand eines Beispiels eine mögliche Realisierung von Topic Maps mit HTML. Das dritte Kapitel wurde den TopicMaps-Tools und Anfragesprachen gewidmet. Es wurden kommerzielle sowie freiverfügbare Tools vorgestellt und miteinander verglichen. Danach wurden die beiden Anfragesprachen Tolog und TMQL eingeführt. Im vierten Kapitel wurden die beiden Einsatzgebiete von Topic Maps behandelt. Das sind zum einen die Webkataloge und die Suchmaschinen. Zum anderen ist es möglich, auch im Rahmen vom E-Learning von dem Konzept der Topic Maps zu profitieren. In diesem Zusammenhang wurde erst der Omnigator von Ontopia vorgestellt. Dann wurde das im Laufe dieser Arbeit entwickelte Topic Maps Tool E-Learning -Tracker ausgeführt und erklärt.
