Interval Formal Concept Analysis Approach for Multigranulation Data
摘要
Abstract
Classical concept lattice and property(object)oriented are both important data structures in formal concept analysis,by introducing interval set into these concept lattices, it can obtain interval concept lattice and property(object) oriented concept lattice. It is firstly proved that property-oriented interval set concept lattice and object-oriented interval set concept lattice are anti-order isomorphic. Then, by introducing the idea of multigranularity into formal concept analysis, the paper studies the relationship between interval set concept lattice and that after granulation. Lastly, the internal rela-tionship between object(property)oriented concept lattices is further studied in multigranulation formal contexts.关键词
