Datasets for Apache Mahout

Question

I am looking for datasets that can be used to implement a recommendation system for Apache Mahout. I only know MovieLens Datasets from the GroupLens Research group.

Does anyone know of any other datasets that can be used to implement a recommendation system? I am particularly interested in element-based datasets, although other data types are welcome.

Answer 1

this is Sebastian from Maut.

There is a dataset from a Czech dating site that might interest you: http://www.occamslab.com/petricek/data/

Btw, the term item-based does not refer to a special collaborative filtering approach that refers to the dataset itself, which is usually in the general form of user element triplets, with which most shared filtering approaches work.

We would like to hear your experiment results and impressions (if you want to share them) in our user mail list at [e-mail]

Answer 2

When searching for datasets, I found several sites that list publicly available datasets that can be used for data mining. Some of them can be used for Maut.

Bixo labs

UCI Datasets

Kdnuggets
