Our aim is to employ Formal Concept Analysis (FCA) to support consensual decision making. We adopt a standard setting in which a group of experts express their preferences wit respect to a set of options represented by preference relations. Usually, these preferences are initially quite different, and the experts are encouraged to discuss their opinions to bring them closer together. FCA, particularly its notion of the concept lattice, seems to be a promising tool for analyzing preferences and recommending changes that should lead to consensus. However, first, the preference relations need to be cast into the form of FCA’s formal context(s). In the paper, we propose two approaches to such a casting, study the properties of the implied concept lattice, and point out some directions on how it can be used to support consensus reaching.
