Dear all,

I have computed users sessions of a website. This is, I can represent each user behaviour as a sequence of requested pages.
What I would like now is to be able to recognise the most repeated sequences of pages. Can you give me hints on the best way to implement this? Is there any open source library for helping me in coding this problem? (I'm programming ing Java).

I guess using a tree structure will help. However, if I end up having a weighted Tree where each edge has a frequency regarding the number of user' sequences that have passed through it, how may I discover the most repeated path?

Thank you in advance!
