- Abstract
- Der vorliegende Artikel bietet einen Überblick über statistische Verfahren der Textanalyse im Kontext des Semantic Webs. Als Einleitung erfolgt die Diskussion von Methoden und gängigen Techniken zur Vorverarbeitung von Texten wie z. B. Stemming oder Part-of-Speech Tagging. Die so eingeführten Repräsentationsformen dienen als Basis für statistische Merkmalsanalysen sowie für weiterführende Techniken wie Information Extraction und maschinelle Lernverfahren. Die Darstellung dieser speziellen Techniken erfolgt im Überblick, wobei auf die wichtigsten Aspekte in Bezug auf das Semantic Web detailliert eingegangen wird. Die Anwendung der vorgestellten Techniken zur Erstellung und Wartung von Ontologien sowie der Verweis auf weiterführende Literatur bilden den Abschluss dieses Artikels.

- Abstract
- In representing the shared view of all the people involved, building a knowledge organization system (KOS) from scratch is extremely costly, and it is therefore fundamental to reuse existing resources. This can be done by progressively extending the KOS with knowledge coming from similar KOSs and by promoting interoperability among them. The linked data initiative is indeed encouraging people to share and integrate their datasets into a giant network of interconnected resources. This enables different applications to interoperate and share their data. The integration should take into account the purpose of the datasets, however, and make explicit the semantics. In fact, the difference in the purpose is reflected in the difference in the semantics. With this paper we (a) highlight the potential problems that may arise by not taking into account purpose and semantics; (b) make clear how the difference in the purpose is reflected in totally different semantics and (c) provide an algorithm to translate from one semantics into another as a preliminary step towards the integration of ontologies designed for different purposes. This will allow reusing the ontologies even in contexts different from those in which they were designed.

- Abstract
- The Entity-Relationship (ER) model is a fundamental formalism for conceptual modeling in database design; it was introduced by Chen in his milestone paper, and it is now widely used, being flexible and easily understood by practitioners. With the rise of the Semantic Web, conceptual modeling formalisms have gained importance again as ontology formalisms, in the Semantic Web parlance. Ontologies and conceptual models are aimed at representing, rather than the structure of data, the domain of interest, that is, the fragment of the real world that is being represented by the data and the schema. A prominent formalism for modeling ontologies are Description Logics (DLs), which are decidable fragments of first-order logic, particularly suitable for ontological modeling and querying. In particular, DL ontologies are sets of assertions describing sets of objects and (usually binary) relations among such sets, exactly in the same fashion as the ER model. Recently, research on DLs has been focusing on the problem of answering queries under ontologies, that is, given a query q, an instance B, and an ontology X, answering q under B and amounts to compute the answers that are logically entailed from B by using the assertions of X. In this context, where data size is usually large, a central issue the data complexity of query answering, i.e., the computational complexity with respect to the data set B only, while the ontology X and the query q are fixed.

- Abstract
- In diesem Dokument sollen Begriffe, Prinzipien und Methoden vorgestellt werden, die sich als hilfreich bei der Erstellung von Semantic Web konformen Repräsentationen von Wissensorganisationssystemen (KOS) erwiesen haben, wie z. B. Thesauri und Klassifikationssysteme. Das Dokument richtet sich an Organisationen wie z. B. Bibliotheken, die ihre traditionellen Wissensorganisationssysteme im Rahmen des Semantic Web veröffentlichen wollen. Die in diesem Dokument beschriebenen Vorgehensweisen und Prinzipien sind nicht als normativ anzusehen. Sie sollen nur dabei helfen, von bisher gemachten Erfahrungen zu profitieren und einen leichteren Einstieg in die wichtigsten Begriffichkeiten und Techniken des Semantic Web zu bekommen. An vielen Stellen wird zudem auf weiterführende Literatur zum Thema und auf relevante Standards und Spezifikationen aus dem Bereich des Semantic Web hingewiesen.

- Abstract
- Der Schwerpunkt dieses Beitrages liegt auf dem Design von Infrastrukturen, welche es ermöglichen sollen, private Daten kontrolliert preiszugeben und auszutauschen. Zunächst wird daran erinnert, dass rechtliche und technische Maßnahmen zum Datenschutz stets auch dazu dienen, den Austausch von Daten zu ermöglichen. Die grundlegende Herausforderung besteht darin, der sozialen und politischen Bedeutung des Privaten Rechnung zu tragen. Privatheit wird aus der Perspektive der Informationsethik dabei als ein normatives, handlungsleitendes Konzept verstanden. Als Maßstab für die Gestaltung der entsprechenden Infrastrukturen wird auf Helen Nissenbaums Konzept der "privacy as contextual integrity" zurückgegriffen, um u. a. die Ansätze der "end-to-end information accountability" und des "Privacy Identity Management for Europe"- Projektes zu diskutieren.

- Abstract
- Das Semantic Web stellt - dzt. noch weitgehend als Entwurf - das bislang letzte Glied einer langen Kette großtechnischer Kommunikationssysteme dar, dessen respektable Vorläufer u. A. die Telegrafie. die Telefonie, der Rundfunk und nicht zuletzt das Internet sind. Als technowissenschaftliche Ambition steht das Semantic Web in der gesellschaftlichen Tradition des abendländischen Aufklärungsprojekts der rationalen Bewirtschaftung von Raum, Zeit. Energie und Zeichen. Auf der Grundlage der sich in den letzten Jahrzehnten bereits weitgehend vollzogenen Medienkonvergenz in der digitalisierten Infrastruktur bildet das Semantic Web - zumindest konzeptiv - einen kongenialen` Gegenpart zur markant ansteigenden Vernetzung der sich globalisierenden Wertschöpfungssysteme, die ihre ökonomischen Potenziale in der fortschreitenden Arbeitsteilung (Spezialisierung) und, komplementär dazu, immer umfassenderen Prozessoptimierung nutzt, die sich beide wiederum in der Hauptsache auf konventionalisierte Bedeutungssysteme zur informationstechnischen - d. h. vor allem: algorithmischen - Koordination stützen. Die soziale Ausformung gerade der Kommunikations- (und Koordinations-) Technologien unterliegt entschieden dem Wechselspiel einzelwirtschaftlicher Akteure bzw. Kapitalverwertungsinteressen und gesamtgesellschaftlicher Technologieadoption, das folgerichtig die charakteristische Innovationsdynamik einschließlich der prävalenten Muster der Ressourcenallokation auch dieser spezifischen Technikgenese prägt.
