In Readme (140), under Log Parsing, the link to the first paper, [IPOM'03] [A Data Clustering Algorithm for Mining Patterns from Event Logs](http://www.quretec.com/u/vilo/edu/2003-04/DM_seminar_2003_II/ver1/P12/slct-ipom03-web.pdf) seems to point to a file that is no longer available. I looked the same paper up and found it under the author's Github page at: https://ristov.github.io/publications/slct-ipom03-web.pdf I believe you can use that link
