        abstract = {We introduce an abstract framework for general rough set theory from a mereological perspective and consider possible concepts of ?a priori? granules and granulation in the same. The framework is ideal for relaxing many of the
relatively super?uous set-theoretic axioms and for improving the semantics of many relation based, cover-based and dialectical rough set theories. This is a
relatively simplified presentation of a section in three different recent research papers by the present author.
