| Abstract: | A new rough set model based on similarity degree is presented in multi-value information systems.Then the reduct of the rough set are studied and the discernibility matrix based on similarity degree is defined.The reducts in multi-value information systems are introduced by the discernibility matrix. |

| Keywords: | multi-value information systems rough set similarity degree discernibility matrix reduct |
