Hi all,
I'm experimenting with Mahout by connecting it to Spotify <http://spotify.com/
>, a service that streams music on the net. It would be really cool
if you people could help me with a a ground truth. The data will of
course be released to the public.
At first I tried to use playlists I scraped from the net as
recommendation profiles. I'm not sure if it is my thesis that a user
always likes everything they put in their own small and non
collaborative playlists was wrong or if there was something else that
made that strategy fail, so I have started from scratch with only real
user preferences. For now it's something like 10 users and 500
preferences, so don't expect it to produce great results.

It will register your account the first to you login, and it will show
you in clear text what password you choose, so choose something silly.
You use plain text queries or Spotify URIs in the search form. Start
with spotify:user:karl.wettin:playlist:1LOXpeOdStzoavRodI4zXZ to
connect with an already existing neighborhood. But please also try to
add some ratings to tracks not available in that playlist, preferably
some 10+.
Finally hit "Our recommendations" in order to get some results.
I have a handful of invites to Spotify if you don't have an account.
Not needed to use the Tastify service though, only if you want to play
the music.
Beware of the GUI. Lots of bugs, please report them if you see them.
The serivce will go up and down now and then. Try to relogin if you
get an exception.
