| 摘 要： | Concept lattice is an efficient formal tool for data analysis and knowledge extraction. However, the present research presumes that all the intensions of concept lattice are equally important. In order to make the best use of concept lattice for analyzing data, extracting knowledge and effectively guiding the decision-making management, the weight value is introduced into the intension of the concept lattice and a new concept lattice, a weighted concept lattice （WCL） is presented, which develops the concept lattice structure. Then one FWCL （Frequent Weighted Concept Lattice） incremental construction method is offered and relative analysis together with an example is presented to illustrate its efficiency and feasibility.
