Abstract : This report results from a contract tasking Institute of Theoretical and Applied Informatics as follows: The contractor will investigate rough set theory and data mining for applications in materials science and other engineering disciplines. The paper gives basic ideas of rough set theory - a new approach to vague data analysis. The lower and the upper approximation of a set the basic operations of the theory, are intuitively explained and formally defined. Some applications of rough set theory are briefly outline and some future problems pointed out.
