Abstract

This text introduces the standardized knowledge representation languages for modeling ontologies operating at the core of the semantic web. It covers RDF schema, Web Ontology Language (OWL), rules, query languages, the OWL 2 revision, and the forthcoming Rule Interchange Format (RIF). A 2010 CHOICE Outstanding Academic Title ! The nine chapters of the book guide the reader through the major foundational languages for the semantic Web and highlight the formal semantics. ! the book has very interesting supporting material and exercises, is oriented to W3C standards, and provides the necessary foundations for the semantic Web. It will be easy to follow by the computer scientist who already has a basic background on semantic Web issues; it will also be helpful for both self-study and teaching purposes. I recommend this book primarily as a complementary textbook for a graduate or undergraduate course in a computer science or a Web science academic program. --Computing Reviews, February 2010 This book is unique in several respects. It contains an in-depth treatment of all the major foundational languages for the Semantic Web and provides a full treatment of the underlying formal semantics, which is central to the Semantic Web effort. It is also the very first textbook that addresses the forthcoming W3C recommended standards OWL 2 and RIF. Furthermore, the covered topics and underlying concepts are easily accessible for the reader due to a clear separation of syntax and semantics ! I am confident this book will be well received and play an important role in training a larger number of students who will seek to become proficient in this growing discipline.

Der Band geht auf die internationale Tagung Die wachsende Macht von Suchmaschinen im Internet: Auswirkungen auf User, Medienpolitik und Medienbusiness bestehend aus einem interdisziplinären wissenschaftlichen Workshop am 26. Juni 2006 und einer Publikumskonferenz am 27. Juni 2006 in Berlin zurück, die vom Lehrstuhl für Journalistik II der Universität Leitung und dem Lehrstuhl für Internationalen Journalismus der UniversitSt Dortmund in Kooperation mit der Friedrich-Ebert-Stiftung, Bereich Medien und Politik, veranstaltet worden ist. In drei Kapiteln werden die zentralen Forschungsfelder aufgegriffen: Das erste Kapitel behandelt die wichtigsten Aspekte im Bereich der Suchmaschinenregulierung und -ökonomie. Es werden Herausforderungen transparent gemacht, die sich gegenwärtig in der Entwicklung befindlichen Regulierungsstrukturen analysiert und Lösungswege erarbeitet. Das zweite Kapitel beschäftigt sich, zum ersten Mal in Form einer Publikation, mit dem Verhältnis von Suchmaschinen und Journalismus. Dabei ist die Frage, inwieweit Suchmaschinen einerseits journalistische Funktionen übernehmen und andererseits Journalisten als Rechercheinstrument dienen und wie sich hierdurch das Gefüge des bisherigen Massenkommunikationssystems verändert, von entscheidender Bedeutung.
