  • Please get the following files from Amazon Review Data and put them at the raw/ directory.

  meta_Video_Games.json.gz
  ratings_Video_Games.csv
  reviews_Video_Games.json.gz
  

  • Obtain node features from reviews by gensim.models.doc2vec, and put the .d2v file at raw/.
  • As well as the initial ranked lists, examples as data/Amazon/raw/train_ratings_Video_Games.txt and data/Amazon/raw/test_ratings_Video_Games.txt in the format of [uid] [iid] [label] [initial score].
