I'm looking for a decently sized dataset (more than 100k docs) which consists of bag of words documents along with a list of users where associated to each user is a list of those documents the user has in his or her library. Or even better, where associated to each user is a list of ratings that the user gave to those documents they viewed.
Does anyone know of such a dataset?
I'd really like to get my hands on the Mendeley DataTEL dataset, but they won't respond to my emails.
