The official implementation of the CoCoRec algorithm proposed in the paper "Category-aware Collaborative Sequential Recommendation" which is accepted to SIGIR 2021.
To run the code,
python main_time.py
The datasets are Taobao (https://tianchi.aliyun.com/dataset/dataDetail?dataId=649) and BeerAdvocate (http://jmcauley.ucsd.edu/cse255/data/beer/). Basically any dataset having sequences of user actions and the category information of items can be used for the algorithms.
