Knowledge organization is the key factor in all areas of human intellect and talent. The swift dissemination of knowledge paves the way for the further budding of new bits of information that in turn creates further knowledge. This book covers major facets of knowledge organization. It provides an outline of the knowledge society, particularly in the context of functions and activities of UNESCO. It then describes the traditional ways of knowledge organization and describes the modern views. The views of Birger Hjorland are particularly detailed. The book also enumerates different categories of information and looks at the concepts of information explosion and information overloading. It lists the possible ways of controlling the information and describes the role and functions of 'keywords' as the fundamental building blocks of information. Finally, the book introduces the basic concepts of folksonomy and tagging, while further discussing the basic concepts of domain ontology and semantic web. Subject: Library and Information Science]
