Confusion about the preprocessing of steam dataset

[Dinxin]

I downloaded the steam dataset displayed on https://cseweb.ucsd.edu/~jmcauley/datasets.html, and I found that purchase and play behaviors are in the same file named "australian_users_items.json" while review and recommend data are in the file named "steam_reviews.json". To my disappointment, the users in these two files cannot be aligned in that users are indicated with the "user_id" attribute in "australian_users_items" but the "user_name" attribute in "team_reviews.json". Could you release the preprocessed dataset like Yoochoose in your repo?
