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.

• You can find the full version of recommendation datasets via Movielens, Last-FM, Amazon-book.
• The linkage used in this dataset is from KB4Rec.

		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.
