| Abstract: | A partial order decision table based on partial order relation was introduced. The relationship between conditional equivalence classes and decision equivalence classes was studied in a partial order decision table, and methods of core and attribute reduction were expatiated from these classes. Finally, an example was given to illustrate the efficiency of these methods. |

| Keywords: | partial order relation rough sets data analysis core knowledge reduction |
