This page is a distribution site for the collection of Amazon product reviews that can be used for sarcasm and irony analysis experiments. Available are:

- pairs of ironic -- regular reviews written for the same Amazon product;
- unpaired ironic reviews;
- unpaired regular reviews;
- text utterances extracted from ironic reviews that were submitted to support the claim that these reviews were ironic.

The description of the 2-step procedure for corpus collection was introduced in the following paper:

- Elena Filatova, Irony and Sarcasm: Corpus Generation and Analysis Using Crowdsourcing, Proceedings of LREC 2012.

For each review we provide information about the product, for which this review was written, the number of stars that was assigned to the product by its authors, etc.
