<DIV>The increasing volume of information in the contemporary world demands for efficient knowledge management (KM) systems: a logical method of information organization that will allow proper semantic querying to identify things that match meaning in natural language. Therefore, the role of an information manager goes beyond implementing a search and clustering system, to the ability to map and logically present the subject domain and related cross domains. One of the ways an information manager can do this is by using the colon classification system, developed by S.R. Ranganathan, a thought leader in library and information science.<BR><BR>This book answers the need by analyzing ontology tools and techniques, helping the reader develop a conceptual framework from the digital library perspective. Beginning with the concept of knowledge abstraction, before discussing the Solecistic versus the Semantic Web, chapters consider: knowledge organization, the development of conceptual frameworks, untying conceptual tangles, and the concept of faceted knowledge representation.</div>
