A fast incremental algorithm for constructing concept lattices

作者:

Highlights:

• Necessary and sufficient conditions for an attribute set to be a new intent.

• The procedure of searching for canonical generators is improved.

• We prove that the number of children of any concept has an upper bound.

• The procedure of updating the upper neighbors of a new concept is improved.

• An efficient incremental algorithm for constructing concept lattices is proposed.
