Abstract


The concept lattice is based on the binary relationship between objects and attributes of the data set to establish a conceptual hierarchy , vivid simplicity reflects the generalization and specialization relationship between the concepts . It is by the German mathematician will R. 1982 , has been widely used in data mining , information retrieval, software engineering and other fields . This work is mainly focused on : the basic concept lattice theory and applications to data mining , this article intends to do more exploration in these areas , on the one hand, to fully tap the concept lattice potential , on the other hand looking for new data mining algorithms . This article focuses on the following questions : 1 to improve the attribute reduction in concept lattice theory , greatly eliminates redundant computation and improve the efficiency of the reduction . To discuss the concept lattice construction , attribute-based matrix construction algorithm , the algorithm to the same object as a whole , to improve the efficiency of the construction . Meanwhile , the algorithm is based on the attribute reduction , reduction to avoid the cumbersome process of first building and then reduction in construction at the same time . The concept lattice for rule extraction , including association rules and classification rules . Extraction algorithm is based on the idea of the concept lattice , but to avoid the process of construction of grid , is a fast algorithm , and the rules for text classification , the experimental results are satisfactory . 4 , the concept of grid applied to the text clustering , this paper presents a clustering algorithm , as well as several issues need to be addressed as a natural clustering tool . The image data into the form of background , concept lattice image association rules extraction . Finally, the theory of concept lattice in data mining , the prospect of further research directions .
