Role-Aware Modeling for N-ary Relational Knowledge Bases

This repository is the official implementation of our WWW'2021 paper "Role-Aware Modeling for N-ary Relational Knowledge Bases".

Requirements

To install requirements:

python 3.7.4
pytorch 1.1

Running a model

To train (and evaluate) the model in the paper, run this command:

python main.py --dataset FB-AUTO --num_iterations 200 --batch_size 64 --lr 0.005 --dr 0.995 --K 10 --rdim 50 --m 2 --drop_role 0.2 --drop_ent 0.4 --eval_step 1 --valid_patience 10 -ary 2 -ary 4 -ary 5

📋 The ary append for WikiPeople is

-ary 2 -ary 3 -ary 4 -ary 5 -ary 6 -ary 7 -ary 8 -ary 9

📋 The ary append for JF17K is

-ary 2 -ary 3 -ary 4 -ary 5 -ary 6

📋 The ary append for WN18/FB15k is

-ary 2

Evaluation interval is determined by the parameter "eval_step"
