Datasets for Apache Mahout

Question

I am looking for datasets that can be used for implementing recommendation system usecase of Apache Mahout. I know of only MovieLens Data Sets from GroupLens Research group.

Anyone knows any other datasets that can be used for recommendation system implementation? I am particularly interested in item-based data sets though other datasets are most welcome.

Answer 1

Hi, this is Sebastian from Mahout.

There is a dataset from a czech dating website available that might be of interest to you: http://www.occamslab.com/petricek/data/

Btw the term item-based refers to a special collaborative filtering approach not to the dataset itself, which is usually in the common form of user-item-rating tripels that most collaborative filtering approaches work with.

We would love to hear from your experimentation results and experiences (if you wanna share them) on our user mailinglist at [email protected]

Answer 2

While searching for data sets, I found few sites that list publicly available data sets which can used for data mining. Some of these can be used for Mahout too.
