Formal concept analysis is a lattice-theoretic framework devised for the extraction of
knowledge from Boolean data tables. A possibility-theoretic view of formal concept analysis
has been recently introduced, and in particular set-valued counterparts of the four set-
functions, respectively, evaluating potential or actual, possibility or necessity, that underlie
bipolar possibility theory. It enables us to retrieve an enlarged perspective for formal concept
analysis, already laid bare by some researchers like Dünsch and Gediga, or Georgescu and …
