This is our implementation of DeepCoNN

DeepCoNN

This is our implementation for the paper:

Lei Zheng, Vahid Noroozi, and Philip S Yu. 2017. Joint deep modeling of users and items using reviews for recommendation. In WSDM. ACM, 425-434.

Two models:

1、DeepCoNN: This is the state-of-the-art method that uti-lizes deep learning technology to jointly model user and itemfrom textual reviews.

2、DeepCoNN++: We extend DeepCoNN by changing its share layer from FM to our neural prediction layer.

The two methods are used as the baselines of our method NARRE in the paper:

Chong Chen, Min Zhang, Yiqun Liu, and Shaoping Ma. 2018. Neural Attentional Rating Regression with Review-level Explanations. In WWW'18.

Please cite our WWW'18 paper if you use our codes. Thanks!
