Approximation Spaces and Information Granulationoximation, and some other information granule approximations. In modelling of such approximation spaces we use an important assumption that not only objects but also more complex information granules involved in approximations are perceived using only partial information about them.

Granular Language and Its Applications in Problem Solvinglas are amalgamated into an answer of the global formula. If the formula is described as a granulation, then it will be collapsed into several sub-granules. So, the collapsing algorithm and rules of amalgamating will be defined. In order to realizing the idea in above, a granular language and its calculus will be discussed.

Generalizations of Rough Sets: From Crisp to Fuzzy Casestracted decision rules. Moreover, we extend the discussion to fuzzy rough sets. Through this paper, the relations among generalized crisp rough sets and fuzzy rough sets are clarified and two different directions of applications in rule extraction are suggested.

Structure of Rough Approximations Based on Molecular Latticesonsequently, the approximation operators, which are more general and abstract compared with approximation operators reported in some papers, are defined based on the frame of molecular lattices. The properties of the approximations are also studied.

Rough Truth, Consequence, Consistency and Belief Revisionse it for a proposal of .. During change, the operative constraints on a system of beliefs are that of . consistency preservation and deductive closure with respect to .. Following the AGM [1] line, postulates for defining revision and contraction functions are presented. Interrelationships of these functions are also proved.
