FCA(Formal Concept Analysis), which is accurate and complete in knowledge representation, is an effective tool for data analysis and knowledge discovery. A new lattice structure named RCL (Rough Concept Lattice) is presented. Using the approximation method of rough sets, we described the extent as approximation extent so that it can deal with uncertainty knowledge. In the end, a construction algorithm CARCL is provided based on it.
