Abstract：Uncertain knowledge acquisition is a problem when no prior domain knowledge is available. The relationship of knowledge uncertainties among three different knowledge presentation models, i.e. decision table, decision rule, and concept lattice, is discovered through analyzing their knowledge presentation styles. A datadriven automatic uncertain knowledge acquisition algorithm based on concept lattice is developed by using this relationship. Experimental results show that this algorithm is valid for acquiring uncertain knowledge.
