Semantic Web for the Working Ontologist

Effective Modeling in RDFS and OWL

The promise of the Semantic Web to provide a universal medium to exchange data information and knowledge has been well publicized. There are many sources too for basic information on the extensions to the WWW that permit content to be expressed in natural language yet used by software agents to easily find, share and integrate information. Until now individuals engaged in creating ontologies-- formal descriptions of the concepts, terms, and relationships within a given knowledge domain-- have had no sources beyond the technical standards documents. Semantic Web for the Working Ontologist transforms this information into the practical knowledge that programmers and subject domain experts need. Authors Allemang and Hendler begin with solutions to the basic problems, but don’t stop there: they demonstrate how to develop your own solutions to problems of increasing complexity and ensure that your skills will keep pace with the continued evolution of the Semantic Web.

Analysts in finance, defense, manufacturing, aerospace industries; scientists in life sciences; physicists; and chemists; developers and their managers.

  • "The Missing Link: Hendler and Allemang's new book is exactly what our industry is looking for. We have many introductory books, and some detail compilations of papers but very little to help a practitioner move up their experience curve from novice to journeyman ontologist. The book is very readable; the examples are plentiful and accessible. I’ve already begun recommending students and clients to pre-order this book.”--David McComb, President, Semantic Arts, Inc.
