要約(日本語): Toward efficient management of enterprise file server, listing potentially unnecessary files is expected to be effective. For this purpose, we propose a method of extracting frequent file access pattern to sort out files accessed by processes of operating system or of file system, which are supposed to be highly frequent. In our method, access sequence of one user ID at short time intervals is processed in four steps: 1) encoded based on relative position in folder tree structure, 2) separated into independent sub-trees, and 3) evaluated according to occurrence probability and frequency of observation. We apply our method to file server access logs of a company and demonstrate that it can extract characteristic access patterns although when multiple processes perform access in parallel.
