The author systematically introduces the notion of ontologies to the
non-expert reader and demonstrates in detail how to apply this
conceptual framework for improved intranet retrieval of corporate
information and knowledge and for enhanced Internet-based electronic
commerce. He also describes ontology languages (XML, RDF, and OWL) and
ontology tools, and the application of ontologies. In addition to
structural improvements, the second edition covers recent developments
relating to the Semantic Web, and emerging web-based standard languages.
