Main Article Content
This paper mainly discusses the rule acquisition of incomplete formal decision contexts based on three-way concept lattice. Firstly, we define the three-way concept lattice over the incomplete formal decision context, and illustrate it using the example. Secondly, we discuss the rules acquisition under the given incomplete formal decision context, and give out four kinds of decision rules and definition of redundant rule. Lastly, we study the judgment of consistent set of three-way concept lattices of incomplete formal decision context, and we give out the judgment theorem of consistent set based on AE-discernibility attributes set.
