Rough Truth, Consequence, Consistency and Belief Revisionformal deductive apparatus . [12], that is sound and complete with respect to a semantics based on rough truth (extended to rough validity). The notion of . [4] is used in a modified form to formulate .. The system has some desirable features of ‘rough’ reasoning – e.g. roughly true propositions can

Fuzzy Reasoning Based on Propositional Modal Logictation of fuzzy assertion based on propositional modal logic. As an extension of the traditional semantics about the modal logics, the fuzzy Kripke semantics are considered and the formal system of the fuzzy reasoning based on propositional modal logic is established and the properties about the sat

Granular Language and Its Applications in Problem Solvingntly, the solutions of various sub-problems are amalgamated into an answer of the global problem. The solving problem in practice is represented by a logical formula, and then the formula is decomposed into several sub-formulas, until into propositions or predicates. The solutions of these sub-formu

Toward Rough Knowledge Bases with Quantitative Measures provides a uniform formalism for expressing rough data together with background knowledge, and for capturing well-known techniques such as the variable precision rough set model. Its essential feature is the use of quantitative measures, such as support, strength and accuracy.

Research on Integrating Ordbms and Rough Set Theoryigned to implement the tight coupling between rough set and ORDBMS. Equivalence matrices algebra doesn’t meet this requirement and must be extended. We extend the equivalence matrices algebra to define the low and upper approximation, relative core and reduction. A prototype system has been designed
