UPGAN (User Preference enhanced GAN)

This is our Pytorch implementation for the paper:

Gaole He, Junyi Li, Wayne Xin Zhao, Peiju Liu and Ji-Rong Wen (2020). Mining Implicit Entity Preference from User-Item Interaction Data for Knowledge Graph Completion via Adversarial Learning. paper, video, slides. In WWW'2020, Taipei, Taiwan, China, April 20–24, 2020.

Introduction

In this paper, we take a new perspective that aims to leverage rich user-item interaction data (user interaction data for short) for improving the KGC task. Our work is inspired by the observation that many KG entities correspond to online items in application systems.

Requirements:

  • Python 3.6
  • Pytorch >= 1.0

Dataset

We provide three processed datasets in : Movielens, Last-FM, and Amazon-book.

Movie Music Book
#Users 61,859 57,976 75,639
User Interaction #Items 17,568 55,431 22,072
#Interactions 9,908,778 2,605,262 831,130
#Entities 56,789 108,930 79,682
Knowledge Graph #Relations 47 45 38
#Triplets 953,598 914,842 400,787

Each dataset is organized with following structure:

  • data-name/
    • rs/
      • u_map.dat: user id mapping file;
      • i_map.dat: item id mapping file;
      • i2kg_map.tsv: mapping from original item id to freebase entity;
      • ratings.txt: raw rating file of dataset.
    • kg/
      • e_map.dat: entity id mapping file;
      • r_map.dat: relation id mapping file;
      • train.dat: mapped triples of train set;
      • valid.dat: mapped triples of validation set;
      • test.dat: mapped triples of test set.
