Application Research of Dominance Relation Rough Set on Seismology Data

In this paper, after discussing classical rough set theory based on indiscemibility relation and the problem of its reduction algorithms on Seismology Data, we arrived at a new definition of dominance distinguishing matrix by taking advantage of the unique characteristic of the extended model. Then the corresponding reduction and rule extracting algorithms are accordingly presented to enhance the efficiency of seeking the reduction in some extent. In fact, we use the rough set theory based on Dominance Relation to get the 272 rules with realistic meaning, from 44381 items in the small Seismology Data in China.
