In order to make up for the gap in knowledge representation in the process of concept modeling based on the formal concept analysis theory, a formal model of integrating expert knowledge into concept lattice structure is proposed. Firstly, the original lattice is revised by aligning a set of attribute dependencies with a set of implications provided by the concept lattice. Then, the constraint lattice is created by using the extent projection to provide change traces. On this basis, this paper proposes a modeling method based on the formal concept analysis constraint lattice theory to bridge this gap, so as to maintain the consistency of the conceptual model. This method not only provides a way for domain experts to revise the conceptual model, but also retains the traces of changes between the original lattice and the final constraint lattice. Through these changes, experts can track how the concept of the real world is associated with the concept of automatic derivation. Finally, examples are given to illustrate the effectiveness of the method to maintain the consistency of the conceptual model based on constraint lattice.
