In my previous job I worked for a research group studying recommender
systems. We have our own, called MovieLens
among others we use a so called item-item recommender.
We compute similarities between items then look at a
given basket and based on it we choose to recommend the most
similar items no yet selected. The good thing about this method
is that item similarities are more static they don't need
to be recomputed as often.
