Abstract

Granular computing is potentially in knowledge discovery and data mining etc. In this paper, by introducing a partial relation $\underline{\prec} ^{'}$ with set size character to information system, an axiom definition of knowledge granulation for information system is presented, some existing the definitions of knowledge granulation become special forms. These results will be very helpful for understanding the essence of knowledge granulation and uncertainty measurement in information system.
