Reconstructing concept lattices usingnth-order context kernels

Text Processing and Decision Support


To be different from traditional algorithms for concept lattice constructing, a method based onnth-order context kernel is suggested in this paper. The context kernels support generating small lattices for sub-contexts split by a given context. The final concept lattice is reconstructed by combining these small lattices. All relevant algorithms are implemented in a system IsoFCA. Test shows that the method yields concept lattices in lower time complexity than Godin algorithm in practical case.
