Abstract

Basically, fuzzy logic is the logic of classes with unsharp boundaries. In human cognition, classes with unsharp boundaries are the norm rather than exception. Everyday examples are the concepts of red, small, near, fast, heavy, similar, etc. A major application area in fuzzy logic is Computing with Words (CW or CWW). Computing with Words is a system of computation which offers an important capability which traditional systems of computation do not have–the capability to compute with information described in natural language. This capability opens the door to a wide-ranging enlargement of the role of natural languages in scientific theories.
