The Special Session is focused on theoretical and applied tools for representing and modelling information. In particular, our interest is in the direction of recent techniques for dealing with uncertainty. In this sense, Formal Conceptual Analysis, Logic Programming and Fuzzy Relation Equations, together with their fuzzy extensions, arise as reliable tools for dealing with knowledge obtained from databases that are uncertain in some way, such as incomplete, imprecise, ambiguous, graded. These are some of the highlighted topics of interest in the session, but contributions related to other fields are also welcome.
