Abstract：A concept lattice is an efficient tool for data analysis and rule extraction, but in factual application the data which are wanted to be dealt with are magnanimity, so it results in too much redundancy of extracting rules immediately based upon concept lattice and brings to the waste of the computing space and the computing time of the computer. Rough set theory has the strong competence to deal with data pretreatment and distill the incertitude rules. Consequently, in order to reduce the waste of manpower and material resource, the paper proposed a method which applied rough set to construct the concept lattice, and gave out the goodness and fault of the algorithm.
