    Abstract
    Im fünften Kapitel wurden die neuen Suchmaschinen, die ausschließlich auf dem Konzept der Topic Maps basieren und diese Technik auch tatsächlich verwenden, angesprochen und mit Beispielanfragen erläutert. In dieser Diplomarbeit wurden wegen dem großen Einsatzpotential von Topic Maps, viele Gebiete angesprochen, angefangen bei den Webkatalogen über Suchmaschinen bis hin zum E-Learning. Mit XML Topic Maps gibt man den Beziehungen zwischen den verschiedenen Topics die Chance sich auszuzeichnen. Damit erreicht die Suche eine neue, bis dahin unmögliche Qualität. Mit einer Topic Map lassen sich beispielsweise die klassischen Navigationselemente technischer Dokumentation (Inhalt, Index, Glossar etc.) in einheitlicher Weise beschreiben; eine andere Topic Map könnte die inhaltliche Vernetzung von Artikeln in einem Lexikon ausdrücken (z.B. Person A wurde geboren in Stadt B, B liegt in Land C, Oper D wurde komponiert von A, Person E war Zeitgenosse von A) und für "siehe auch"-Verweise sorgen (andere Werke dieses Komponisten, andere Städte in diesem Land etc.). Es klingt wie die Lösung aller Suchprobleme. Allerdings nur in der Theorie. Denn Tools, die in der Lage sind, das Wissen oder die Riesendaten in Topicmaps automatisch zu generieren, sind noch Mangelware, was die Ausbreitung von Topic Maps hemmt. Der Aufbau solcher Netze erfordert sehr viel Zeit und sehr viel "Handarbeit" - und damit auch viel Geld, was viele Firmen davon abhält Topic Maps zu benutzen.

    Abstract
    This paper is about the relationship between the topic map and RDF standards families. It compares the two technologies and looks at ways to make it easier for users to live in a world where both technologies are used. This is done by looking at how to convert information back and forth between the two technologies, how to convert schema information, and how to do queries across both information representations. Ways to achieve all of these goals are presented. This paper extends and improves on earlier work on the same subject, described in [Garshol01b]. This paper was first published in the proceedings of XML Europe 2003, 5-8 May 2003, organized by IDEAlliance, London, UK.

    Abstract
    There have been many attempts at classifying the semantic modification relations (R) of N + N compounds but this work has not led to the acceptance of a definitive scheme, so that devising a reusable classification is a worthwhile aim. The scope of this undertaking is extended to other binominal lexemes, i.e. units that contain two thing-morphemes without explicitly stating R, like prepositional units, N + relational adjective units, etc. The 25-relation taxonomy of Bourque (2014) was tested against over 15,000 binominal lexemes from 106 languages and extended to a 29-relation scheme ("Bourque2") through the introduction of two new reversible relations. Bourque2 is then mapped onto Hatcher's (1960) four-relation scheme (extended by the addition of a fifth relation, similarity , as "Hatcher2"). This results in a two-tier system usable at different degrees of granularities. On account of its semantic proximity to compounding, metonymy is then taken into account, following Janda's (2011) suggestion that it plays a role in word formation; Peirsman and Geeraerts' (2006) inventory of 23 metonymic patterns is mapped onto Bourque2, confirming the identity of metonymic and binominal modification relations. Finally, Blank's (2003) and Koch's (2001) work on lexical semantics justifies the addition to the scheme of a third, superordinate level which comprises the three Aristotelean principles of similarity, contiguity and contrast.

    Abstract
    AGI - Information Management Consultants liefern seit nunmehr 16 Jahren eine Software zur Entwicklung von Thesauri und Klassifikationen, ehemals bezeichnet als INDEX, seit zweieinhalb Jahren als IC INDEX neu entwickelt. Solche Terminologien werden oft auch als Glossar, Lexikon, Topic Maps, RDF, semantisches Netz, Systematik, Aktenplan oder Nomenklatur bezeichnet. Die Software erlaubt zwar schon immer, dass solche terminologischen Werke mehrsprachig angelegt sind, doch es gab keine speziellen Werkzeuge, um die Übersetzung zu erleichtern. Die Globalisierung führt zunehmend auch zur Mehrsprachigkeit von Fachterminologien, wie laufende Projekte belegen. In IC INDEX 5.08 wurde deshalb ein spezieller Workflow für die Übersetzung implementiert, der Wortfelder bearbeitet und dabei weitgehend automatisch, aber vom Übersetzer kontrolliert, die richtigen Verbindungen zwischen den Termen in den anderen Sprachen erzeugt. Bereits dieser Workflow beschleunigt wesentlich die Übersetzungstätigkeit. Doch es geht noch schneller: der eTranslation Server von Linguatec generiert automatisch Übersetzungsvorschläge für Deutsch/English und Deutsch/Französisch. Demnächst auch Deutsch/Spanisch und Deutsch/Italienisch. Gerade bei Mehrwortbegriffen, Klassenbezeichnungen und Komposita spielt die automatische Übersetzung gegenüber dem Wörterbuch-Lookup ihre Stärke aus. Der Rückgriff ins Wörterbuch ist selbstverständlich auch implementiert, sowohl auf das Linguatec-Wörterbuch und zusätzlich jedes beliebige über eine URL adressierbare Wörterbuch. Jeder Übersetzungsvorschlag muss vom Terminologie-Entwickler bestätigt werden. Im Rahmen der Oualitätskontrolle haben wir anhand vorliegender mehrsprachiger Thesauri getestet mit dem Ergebnis, dass die automatischen Vorschläge oft gleich und fast immer sehr nahe an der gewünschten Übersetzung waren. Worte, die für durchschnittlich gebildete Menschen nicht mehr verständlich sind, bereiten auch der maschinellen Übersetzung Probleme, z.B. Fachbegriffe aus Medizin, Chemie und anderen Wissenschaften. Aber auch ein Humanübersetzer wäre hier ohne einschlägige Fachausbildung überfordert. Also, ohne Fach- und ohne Sprachkompetenz geht es nicht, aber mit geht es ziemlich flott. IC INDEX basiert auf Lotus Notes & Domino 5.08. Beliebige Relationen zwischen Termen sind zulässig, die ANSI-Normen sind implementiert und um zusätzliche Relationen ergänzt, 26 Relationen gehören zum Lieferumfang. Ausgaben gemäß Topic Maps oder RDF - zwei eng verwandte Normen-werden bei Nachfrage entwickelt. Ausgaben sind in HMTL, XML, eine ansprechende Druckversion unter MS Word 2000 und für verschiedene Search-Engines vorhanden. AGI - Information Management Consultants, Neustadt an der Weinstraße, beraten seit 1983 Unternehmen und Organisationen im dem heute als Knowledge Management bezeichneten Feld. Seit 1994 liefern sie eine umfassende, hochintegrative Lösung: "Information Center" - darin ist IC INDEX ein eigenständiges Modul zur Unterstützung von mehrsprachiger Indexierung und mehrsprachigem semantischem Retrieval. Linguatec, München, ist einstmals aus den linguistischen Forschungslabors von IBM hervorgegangen und ist über den Personal Translator weithin bekannt.

    Abstract
    Der Einsatz von semantischen Technologien ist mittlerweile ein etabliertes Mittel zur Optimierung von Information-Retrieval-Systemen. Obwohl der Einsatz von Ontologien für verschiedene Anwendungsbereiche wie beispielsweise zur Query-Expansion (Bhogal et al. 2007), zur Strukturierung von Benutzeroberflächen bzw. zur Dialoggestaltung (z. B. Garcia & Sicilia 2003; Liu et al. 2005; Lopez et al. 2006; Paulheim 2009; Paulheim & Probst 2010), in Recommendersystemen (z. B. Taehee et al. 2006; Cantador et al. 2008; Middleton et al. 2001; Middleton et al. 2009) usw. rege erforscht wird, gibt es noch kaum Bestrebungen, die einzelnen Abfragemethodiken für Ontologien systematisch zu untersuchen. Bei der Abfrage von Ontologien geht es in erster Linie darum, Zusammenhänge zwischen Begriffen zu ermitteln, indem hierarchische (Classes und Individuals), semantische (Object Properties) und ergänzende (Datatype Properties) Beziehungen abgefragt oder logische Verknüpfungen abgeleitet werden. Hierbei werden sogenannte Reasoner für die Ableitungen und als Abfragesprache SPARQL (seltener auch XPath) eingesetzt. Ein weiterer, weniger oft eingesetzter, vielversprechender Ansatz findet sich bei Hoser et al. (2006) und Weng & Chang (2008), die Techniken der Sozialen Netzwerkanalyse zur Auswertung von Ontologien miteinsetzen (Semantic Network Analysis). Um die Abfrage von Ontologien sowie Kombinationen der unterschiedlichen Abfragemöglichkeiten systematisch untersuchen zu können, wurde am SII eine entsprechende Testumgebung entwickelt, die in diesem Beitrag genauer vorgestellt werden soll.

    Abstract
    Linguists in the structuralist tradition (e.g., Lyons, 1977; Saussure, 1959) have asserted that concepts cannot be defined on their own but only in relation to other concepts. Semantic relations appear to reflect a logical structure in the fundamental nature of thought (Caplan & Herrmann, 1993). Green, Bean, and Myaeng (2002) noted that semantic relations play a critical role in how we represent knowledge psychologically, linguistically, and computationally, and that many systems of knowledge representation start with a basic distinction between entities and relations. Green (2001, p. 3) said that "relationships are involved as we combine simple entities to form more complex entities, as we compare entities, as we group entities, as one entity performs a process on another entity, and so forth. Indeed, many things that we might initially regard as basic and elemental are revealed upon further examination to involve internal structure, or in other words, internal relationships." Concepts and relations are often expressed in language and text. Language is used not just for communicating concepts and relations, but also for representing, storing, and reasoning with concepts and relations. We shall examine the nature of semantic relations from a linguistic and psychological perspective, with an emphasis on relations expressed in text. The usefulness of semantic relations in information science, especially in ontology construction, information extraction, information retrieval, question-answering, and text summarization is discussed. Research and development in information science have focused on concepts and terms, but the focus will increasingly shift to the identification, processing, and management of relations to achieve greater effectiveness and refinement in information science techniques. Previous chapters in ARIST on natural language processing (Chowdhury, 2003), text mining (Trybula, 1999), information retrieval and the philosophy of language (Blair, 2003), and query expansion (Efthimiadis, 1996) provide a background for this discussion, as semantic relations are an important part of these applications.
