information systems which is an important formal framework for the development
of data mining. In this study, in terms of introducing dominance relations,
a rough set approach in interval ordered information systems is first established.
Then, the concept of dominance entropy and dominance combination entropy in
interval ordered information systems is come up with. Finally, through calculating
of dominance entropy and dominance combination entropy in interval information
systems based on dominance relations, it is proved that in the wake of enhancement
of knowledge discernment, dominance entropy and dominance combination entropy
increases monotonously. These results give a kind of feasible approaches to
discover and acquisition of knowledge in interval ordered information systems.]]>Cheng, S.W., R.W. Dai, W.X. Xu and Y. Shi,20065585596Shi, Y., Y. Peng, W.X. Xu and X.W. Tang,20021131151Greco, S., B.
