Rough concept lattice and construction arithmetic
Jifu Zhang · Computer Engineering and Applications Journal · 2007
Concept lattice,which is accurate and complete in KR(Knowledge Representation),is an effective tool for data analysis and knowledge discovery.A new lattice structure named RCL(Rough Concept Lattice) is presented.Based on Decision Context, using the approximation method of rough sets,RCL describes the extent as approximation extent.It can deal with uncertainty knowledge.A construction arithmetic CARCL is provided based on it.
