Amazon Reviews

Product reviews from Amazon and collected by SNAP. The modes represent user-product-word, and each non-zero is the number of times a word appears in a given review. We pre-processed the review text by removing stop words and performing Porter stemming.

Please note that we no longer have the mappings for this dataset. It is provided as a peformance benchmark.
