Abstract

An ontology is a description (like a formal specification of a program) of concepts and relationships that can exist for an agent or a community of agents. The concept is important for the purpose of enabling knowledge sharing and reuse. The Handbook on Ontologies provides a comprehensive overview of the current status and future prospectives of the field of ontologies. The handbook demonstrates standards that have been created recently, it surveys methods that have been developed and it shows how to bring both into practice of ontology infrastructures and applications that are the best of their kind.

Footnote

Rez. in: KO 36(2009) no.2/3, S.178-180 (Birger Hjørland): " ... Theories of Geographic Concepts offers, despite such omissions, a rich and valuable overview of a complicated field. The different perspectives it presents are views and concepts that are at the centre of attention in contemporary research. Our field of KO cannot afford to ignore this literature and it is important that we come in closer contact with specific domains, including geography. This book should therefore be included in libraries and collections serving research and teaching in Knowledge Organization."
