This is a book about what has Ontoprise(in other words Karlsruhe Uni.) done in asocciation with Innsbruk and Amsterdam (and probably Manchester I cannot recall) for the development of software tools about the semantic web. That's why the title of the book has the word "Towards" before "Semantic Web" and it is not just called "The Semantic Web". It talks very little about the Semantic Web, Ontologies and the problems that we face in the realization of these concepts and is limited to just introducing some concepts without defining and explaining them in detail.The only pesron that this book might seem usefull is someone who is prety aware of the semantic web and ontology technologies and wants to find more information about the way the way some problems are dealt in software.
