| Abstract: | The construction of three-way concept is one of the important research subjects of three-way formal concept analysis. To enrich the research of three-way concept, an algorithm for constructing the three-way concept is proposed by using the matrix structure. First, the definition of attribute matrix is given, which displays or shows attributes and its classes. Then the algorithm of the attribute-induced three-way concept is constructed based upon the definition. The operation process of the abovementioned algorithm is illustrated with an example and the validity of the algorithm is verified. Second, the definition of object matrix is given and the algorithm of object-induced three-way concept is designed according to the object matrix definition. Similarly, an example is used to illustrate the algorithm process. The above processes or concepts show that the proposed algorithms are correct and effective. The research results provide more choices for the application of three-way concept in data processing. |
