In Readme (140), under Log Parsing, the link to the first paper,
[IPOM'03] A Data Clustering Algorithm for Mining Patterns from Event Logs
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
