Uncertainty, Vagueness and Knowledge 

Realworld information is inescapably incomplete, uncertain, vague, imprecise, inconsistent.
However, intelligent systems, either natural or artificial, do manage to build Knowledge out of such information, and to use it to perform meaningful tasks.
The study of the mathematical foundations and methodologies that underlie this process is the objective of a large scientific community. Such foundations rely on precise mathematical definitions, as probabilities, possibilities, belief functions, imprecise probabilities, fuzzy sets. However, two main problems are still open:
