On CBC Lite users can navigate to a Recommended lineup page at CBC.ca/lite/recommended. This page uses Read events (read this FAQ page for more info on those) to recommended articles based on those you've previously read within the last seven days.
This only counts reading that occurred within the CBC Lite service. The model is specifically uses a Variable Order Markov Model (VOMM) to generate its recommendations, as implemented by an internal team, which you can read more about on wikipedia here.
