CPSCom 2010 Keynote Speech: Witold Pedrycz

Summary form only given. In this paper the fundamentals of information granularity is discussed and a concept of collaborative granular computing is introduced. In social computing, a number of separate streams of information granules generated by individual sources (users, models) and the resulting individual sources of knowledge formed on their basis are faced. It is also discussed that the collaboration and reconciliation of locally available pieces of knowledge ultimately give rise to the concept of higher type information granules, especially fuzzy sets of type-2 and interval-valued fuzzy sets.
