Okay, here's what I'm looking at:
On my site, I want to have a listing of "Similar Articles", which display articles that may also interest the user. Now, I was thinking that maybe this could be done by counting the number of session combinations involving the 2 articles, and the top 5 combos become similar threads.
At the same time, I'm also looking at doing a "Similar Threads" thing which does pretty much the same job.
How would you suggest doing this?
