A knowledge acquisition approach based on the inclusion degree and granular computing

Skowronpsilas discernibility matrix is one of knowledge acquisition approaches from Knowledge Representation System K = (U,C cup D,V,F). This method is easy to understand and manipulate, while redundant information and complicated logic calculations are also involved. To decrease the complexity of computation, the idea of granular computing is applied to lower the rank of discernibility matrix. In addition, the inclusion degree based on bit-vector computation is proposed to simplify computation complexity in knowledge acquisition.
