Aimed at knowledge management professionals and students in the field of knowledge management, information science, information systems and software engineering, the book provides answers to the ‘what-is’ and ‘why-is’ questions with regard to knowledge management. It investigates the concepts and elements, the drivers, and challenges involved in knowledge management. In the second part of the book the ‘how’ and ‘with-what’ characteristics of knowledge management are covered. Although knowledge management is primarily concerned with non-technical issues, this book concentrates on the technical issues and challenges. A new technology framework for knowledge management is proposed to position and relate the different knowledge management technologies as well as the two key applications of knowledge management, namely knowledge portals and knowledge discovery (including text mining).
