Modeling Product's Intrinsic and Extrinsic Characteristics for Recommender Systems

This is our official implementation for the paper:

Bin Wu, Xiangnan He, Yun Chen, Liqiang Nie, Kai Zheng, and Yangdong Ye, Modeling Product's Intrinsic and Extrinsic Characteristics for Recommender Systems, IEEE TKDE, ACCEPT,2020.

If you use the codes, please cite our paper . Thanks!

Model

The core model is src/librec/ranking/IEPMF.java.

Dataset

We exhibit a small dataset Office_Products.txt, in which the columns indicate the user_id, item_id, rating score, respectively. Please first unzip the file Extrinsic_features_Office_Products.zip.

Quick Start

Run the main function in src/librec/main/main.java.

Results

The outputs with default settings are as below:
