   Didn't Firefly get bought by Amazon? I think the Amazon reccomendation engine is based on Firefly...
   
   I was working with a company a few years ago that had software that made reccomendations based on an analysis of the music you liked. Not song title and artist, but beats per minute, tone, bass, innstumentation, etc. The demo was very impressive, but I was never 100% convinved that the demo was not fixed. They were just starting up in late 2000 - and never could land the VC they needed to commericalize the software.

   Recommendation Systems

   I was impressed with the recommendation system used by NetFlix.com. A user can rate a list of movies and receive recommendations about what else they might like. The accuracy is astonishing. After I'd rated a few pages of movies, a good number of the recommendations on my list were movies I already owned.

   The trouble with this is that, yes, they often do come up with things you like/own, but what is the use of that? I want a recommendation system that suggests things that I don't know about and I have yet to come across a system that even gets close to doing this. Amazon is a good case in poitn where you buy a book and your recommendations fill up with crap you have no interest in - as an example I books about Japanese and Japan, but not travel guides, but amazon persists in giving me japan travel guides even though I keep saying "not interested". By one SF book and you are doomed to rejecting reams of utter garbage.

   Firefly were bought by Microsoft. As part of the Firefly work they did stuff on digital identities, which was what Microsoft bought them for to use as the backbone of their Passport service. The original reason for the company - the recommendation work - all got dumped AFAIK.

   There are lots of good recommendation systems out there, but Amazon's recommendation service really hasn't impressed me at all. I suspect it's because it hasn't really got enough information to work with for the vast number of products they deal with. They probably don't get many people to enter ratings data, and when people give it a go, most would give up quickly.
   
   For a much better example of a recommender system, take a look at http://www.movielens.org/
