Abstract (in Japanese) (See Japanese page) 
(in English) Network logs, such as router syslogs are efficient for understanding faulty events or current network states in detail. However, analyzing these logs is a difficult issue due to the diversification of them accompanied with the increased number of network elements and the multivendor environment. In this research, we present a new method for visualizing large scale logs in an efficient fashion for network operation without any previous knowledge about logs. The proposed method provides a whole view of large scale logs by using data compression techniques such as template extraction and log grouping. In addition, it helps network operators to find abnormal logs by extracting abnormality from occurrence patterns of logs. Finally, we evaluate our method using data collected
at some experimental network and demonstrate its efficiency.
