RMV 2013 - Special Session on Representing And Managing Vagueness: Different Scenarios, Different Tools

Organizers: Davide Ciucci, Chris Cornelis, Jesús Medina, Dominik Slezak
The notion of vagueness has been extensively analysed in the last decades by philosophers, logicians and computer scientists. Here we are interested in the vagueness originated by different characteristics and flaws in information: incompleteness, imprecision, graduality, granularity, contradiction between agents, etc. For each of these aspects one (or more) specific tool has been introduced in literature: fuzzy sets, rough sets, possibility theory, formal concept analysis, interval analysis, etc. Further, when more than one form of vagueness are presented at the same time, it seems natural to fuse such tools, as in the fuzzy rough set case. The special session is devoted to collect all contributions that deal with scenarios leading to a form of vagueness and tools to represent and manage it. In particular, all critical discussions, comparisons among two or more forms of vagueness and/or comparisons and fusion of two or more tools are welcome. The not exhaustive list of topics includes: fuzzy sets and logic; rough sets; fuzzy rough sets; interval-valued fuzzy sets; formal concept analysis; possibility theory; supervaluations; near sets; interval analysis; grey sets; soft sets; vague sets; epistemic logic.
