Data Description
Raw Data
For the raw data of Amazon Review Dataset (https://nijianmo.github.io/amazon/index.html).
Here we only use the Digital Music subset of the whole dataset.
These are some statistics which are important for us to have a knowledge on the data:
Original Data
- Total items: 456992
- Total users: 840372
- Total interactions: 1584082
It is clearly that this dataset is extremely sparse. The density of this dataset is only about 0.0004125% which is significantly less than the density of some other commonly used dataset such as: movielens (4.468%). Thus, there are some additional operations need to be done to preprocess the data.
