Average Reviews:
(More customer reviews)There are maybe half a dozen or so books in my library that have defined the body of knowledge that has been the subject of my career. All the others are interesting (or not) but not the definitive description of the subject. It is very rare when a new one comes along. But when one does succinctly and clearly define and describe a subject area I have been struggling to master for several years, this is worth celebrating.
This is such a book. For the last several years, I have been studying OWL and the Semantic Web, recognizing that there is something there that is important. But it's been a struggle to get on top of it. For example, the books I've found so far (and indeed, the OWL specification itself) describes the language in terms of XML. That's ok, and I was able to understand bits and pieces of it. And I did get the fundamental difference between semantic modeling as done in OWL and semantic modeling as I have been doing with entity/relationship modeling. But I never really felt comfortable that I "got it".
This book, however, very clearly starts at the beginning and takes the reader through the steps required to understand not just the languages involved, but why they are important and why they are significant to the Semantic Web. Indeed this is the first time I can say that I really understand the semantic web.
One of the reviews complains that the book doesn't go far enough. Perhaps not. But if you are looking for a place not just to start your education and to get a through grounding in fundamental concepts, this is the book for you.
I strongly recommend this book.

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. . Provides practical information for all programmers and subject matter experts engaged in modeling data to fit the requirements of the Semantic Web.. De-emphasizes algorithms and proofs, focusing instead on real-world problems, creative solutions, and highly illustrative examples. . Presents detailed, ready-to-apply "recipes" for use in many specific situations.. Shows how to create new recipes from RDF, RDFS, and OWL constructs.
