Abstract :
In this paper, we introduce the notion of decision formal context as an extension of the notion of formal context by using the notion of decision information table. Compared with consistent decision information systems, we give the notion of consistent decision formal contexts. Based on the concept of consistent decision formal contexts, we present how to extraction "if-then "rules from the decision formal contexts.
