A Novel Embedding Model for Knowledge Base Completion Based on Convolutional Neural Network

This program provides the implementation of the CNN-based model ConvKB for knowledge graph embeddings as described in the paper. ConvKB uses a convolution layer with different filters of the same 1 × 3 shape and then concatenates output feature maps into a single vector which is multiplied by a weight vector to produce a score for the given triple.

Usage

News

• June 13, 2020: Update Pytorch (1.5.0) implementation. The ConvKB Pytorch implementation, which is based on the OpenKE framework, is to deal with the issue #5.

• May 30, 2020: The Tensorflow implementation was completed approximately three years ago, and now it is out-of-date.

• March 06, 2018: Note that our Tensorflow implementation can leverage different filters of different n × 3 shapes, so we can tune the hyper-parameter n. In our paper, we set n to 1 for simplification.

Requirements

• Python 3.6
• Pytorch 1.5.0 or Tensorflow 1.6

Training

Regarding the Pytorch implementation, you should run ''bash make.sh'' to compile the base package and then use the commands as:

$ python train_ConvKB.py --dataset WN18RR --hidden_size 50 --num_of_filters 64 --neg_num 10 --valid_step 50 --nbatches 100 --num_epochs 300 --learning_rate 0.01 --lmbda 0.2 --model_name WN18RR_lda-0.2_nneg-10_nfilters-64_lr-0.01 --mode train

$ python train_ConvKB.py --dataset FB15K237 --hidden_size 100 --num_of_filters 128 --neg_num 10 --valid_step 50 --nbatches 100 --num_epochs 300 --learning_rate 0.01 --lmbda 0.1 --model_name FB15K237_lda-0.1_nneg-10_nfilters-128_lr-0.01 --mode train
