Based on the formal concept analysis, combining the rough set and semantic ontology, this paper proposes a formal concept similarity measurement by improving the original Tversky similarity model. The method used the hierarchical information of concept lattice in the lattice structure and its own semantic meaning to measure the similarity of from the structure information of the concepts and semantic...
Classical formal concept analysis can't deal with rough and uncertain information, so the research on rough concept lattice and information express has important significance. There is an interesting relationship between approximate space and concept lattice in the rough set theory. The upper-lower approximation and variable precision in rough set theory are introduced into concept lattice, this paper...
