Some problems about data-preprocessing module #3

Closed Peggy1027 closed 1 year ago

Peggy1027 commented 1 year ago

Your work is impressive and helpful for beginners like me to understand the multi-modal recommendation system. But I encountered two problems when running your data-preprocessing module: 1. Your data-preprocessing module seems unable to handle the "complete review data"; I would like to know if you can release these codes; 2. During the remapping process in the "2reindex-feat.ipynb", I found that there would be a mismatch, so the map_dict would be empty. Except for processing the string "true" and "false" in the parse function and modifying the file path, I made no changes. Is there anything wrong?

Hi, Peggy1027, thanks for running our code and giving the above feedback.

  1. Sorry we didn't have the code for preprocessing "complete review data" in http://jmcauley.ucsd.edu/data/amazon/links.html. Because we only use the "Per-category files" and "Files-"Small" subsets for experimentation" rating files.
  2. May we have more detailed information about the content of your 'i_id_mapping' file? Also, we encourage you to use the debugging of IDE/CMD to check why map_dict would be empty. Happy that we can help your research on this topic.

@enoche so the rating files link is http://snap.stanford.edu/data/amazon/productGraph/item_dedup.csv ? 3.2gb in total

oh, I finally know what you mean, thanks for your nice project.
