Abstract: This paper researches the method of discovering Repeated Continuous Frequent Access(RCFA) paths from Web logs. For some problems of existing mining algorithms, matrix is applied to the process of mining in this paper, it proposes conception of CA matrix and discovers repeated continuous frequent access paths by the CA matrix, thereby it has no need to scan database repeatedly and avoids a great deal of intermediate items. To some extent, it simplifies the process of mining. Experiment indicates the accuracy and high efficiency of the algorithm.

Key words: Web log, continiuous frequent access path, Continuous Access(CA) matrix, intermediate item
