KM2.0: Business knowledge sharing in the Web 2.0 age

This paper is intended to discuss the impact of Web 2.0 on knowledge management (KM) and the future orientation of KM. These days, the term KM is used rather less than hitherto. However, as Web 2.0 has made its debut and user participation-type culture has expanded, the new concept of "collective intelligence" has been attracting attention. Opinions are currently being advanced with regard to the concept and process of KM and the system architecture that can be used to implement it. This paper also deals with the issue of knowledge provision, a traditional issue of KM, and introduces a KM model in the context of the Web 2.0 age that can expand collective intelligence in a positive spiral by closely linking it to knowledge extraction from various communication tools and job systems.
