“…Our prior work [8] introduces Granular Computing (GrC) into the research on unified information modeling in network management domain, and discusses the problem from the granularity point of view, and our prior work [9] further studies the problem from the ontology point of view and applies the theory of concept lattices into the research on semantic management information modeling. It seems that, as one origin of GrC, concept lattices can be used to formally describe the meta-schemas for management information modeling, and the theory of concept lattices prospects a promising way to learn concept hierarchy from YANG for the sake of SDN management.…”
