For those who can read french there is an interesting experiment here http://culturewok.com/lewokentravaux/cine

The indexing is based exclusively on mood and the ratings are user-contributed. I can forward contacts if someone wants to know more about the project.

Thanks - that's really interesting. I'd be really interested to know how many user ratings were needed for such fine-grained controls?

How many ? As far as I know, as many ratings as there are movies. Of course, the more ratings the more "accurate" is the system, if we can use such a word for a search engine that aims more for a kind of serendipity attracted by moods than for exact matches (how exact can be this kind of query, btw ?). I many be biased but I feel we need this kind of system at a large scale!
