Dataset Card for Amazon Review Polarity

Dataset Summary

The Amazon reviews dataset consists of reviews from amazon. The data span a period of 18 years, including ~35 million reviews up to March 2013. Reviews include product and user information, ratings, and a plaintext review.

Supported Tasks and Leaderboards

• text-classification , sentiment-classification : The dataset is mainly used for text classification: given the content and the title, predict the correct star rating.

Languages

Mainly English.

Dataset Structure

Data Instances

A typical data point, comprises of a title, a content and the corresponding label.

An example from the AmazonPolarity test set looks as follows:

{
    'title':'Great CD',
    'content':"My lovely Pat has one of the GREAT voices of her generation. I have listened to this CD for YEARS and I still LOVE IT. When I'm in a good mood it makes me feel better. A bad mood just evaporates like sugar in the rain. This CD just oozes LIFE. Vocals are jusat STUUNNING and lyrics just kill. One of life's hidden gems. This is a desert isle CD in my book. Why she never made it big is just beyond me. Everytime I play this, no matter black, white, young, old, male, female EVERYBODY says one thing ""Who was that singing ?""",
    'label':1
}
