Formal L-concepts with Rough Intents
Eduard Bartl, Jan Konečný · 2014
Abstract. We provide a new approach to synthesis of Formal Concept Analysis and Rough Set Theory. In this approach, the formal concept is considered to be a collection of objects accompanied with two collections of attributes—those which are shared by all the objects and those which are possessed by at least one of the objects. We define concept-forming operators for these concepts and describe their properties. Furthermore, we deal with reduction of the data by rough approximation by given equivalence. The results are elaborated in a fuzzy setting. 1
