Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose system that provides similar behavior from the web access log when students learn using the internet. In order to analyze these efficiently, we construct a distributed environment using Apache Hadoop, and discuss the evaluation in several cases. As the result, speed up ratio using Pentium4 with 3 nodes to analyze the data of 1GB is 2.65 times. However, in the case of data is less than 1GB, the distributed environment is not efficient. As for behavior patterns, grouping of students with similar behavior are achieved by using collaborative filtering using Euclidean distance.
