英文摘要：

This paper gives the formal description of the importance of concept intent by importing the concept of information entropy. It reduces the concepts considering the interest of the customer and puts forward the incremental building algorithm of reduced concept lattice. The experiment indicates that this method is an efficient way of decreasing the complexity of concept building algorithm in view of the interest of users.
