I’ve just been doing some poking around on this collaborative filtering based site movielens. Just like amazon spookily accurate with the recommendations. I went through the sign up process and some initial ratings, marking things like Star Wars and Indianna Jones highly, finally they suggest that my top DVD fav would be Scratch… which I love, however nothing like any of the sci-fi, action or noir movies that i rated.
It’s powered by grouplens a research project that’s been investigating collaborative/group-based filtering for the last 10 years (starting with filtering newsnet messages).
