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.

Abstract

Class-tested and coherent, this textbook teaches information retrieval, including web search, text classification, and text clustering from basic concepts. Ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students. Slides and additional exercises are available for lecturers. - This book provides what Salton and Van Rijsbergen both failed to achieve. Even more important, unlike some other books in IR, the authors appear to care about making the theory as accessible as possible to the reader, on occasion including short primers to certain topics or choosing to explain difficult concepts using simplified approaches. Its coverage [is] excellent, the quality of writing high and I was surprised how much I learned from reading it. I think the online resources are impressive.

Abstract

Ein Grundproblem der rechnergestützten Erstellung, Bearbeitung und Archivierung von Dokumenten ist die unzureichende Wiedergabe von Inhalt und Struktur durch die heute verbreiteten Dokumentformate und Seitenbeschreibungssprachen. Die Standard Generalized Markup Language löst dieses Problem druch die präzise und flexible Beschreibung der Struktur von Dokumenten. SGML ermöglicht dadurch die vielseitige Nutzung der in Dokumenten enthaltenen Information für elektronische Publikationen, Hypertext-Systeme, Online-Dokumente, aber auch für die klassischen Formen der Publikation in Buch, Zeitschrift und Loseblattwerk. Darüber hinaus dient der ISO-Standard SGML als Austauschformat in heterogenen DV-Umgebungen. Das Buch vermittelt sowohl die für die Entscheidungsträger notwendigen Informationen als auch das Basiswissen für den Entwickler. Es gibt einen praxisorientierten Einstieg in Vorteile und Anwendungsgebiete von SGML, behandelt anhand vieler Beispiele die verschiedenen Bestandteile von Dokument-Typ-Definitionen und gibt einen Überblick über die verfügbare SGML-Software. Für Anwender von SGML und Entwickler von SGML-Anwendungen, DV-Fachleute in Verlagen, technische Dokumentare und allgemein an Dokumentverarbeitung Interessierte.
