Possible Rough Ingredients of Concepts in Approximation Spaces
Anna Gomolińska · Fundamenta Informaticae · 2006
We discuss the problem of rough ingredients and parts of concepts of an indiscernibility-based approximation space. The notion of a (rough) ingredient is extended to the notion of a (rough) ingredient, and analogously in the case of parts. The term possible means that a concept is perceived as a candidate for a future substitute of some ingredient. Our approach is in line with rough mereology except for allowing the empty concept for the sake of simplicity.
