Graph Transformer

Code for our AAAI2020 paper,

Graph Transformer for Graph-to-Sequence Learning. [preprint]

Deng Cai and Wai Lam.

1. Environment Setup

The code is tested with Python 3.6. All dependencies are listed in requirements.txt.

2. Data Preprocessing

The instructions for Syntax-based Machine Translation are given in the translator_data folder.

The instructions for AMR-to-Text Generation are given in the generator_data folder.

Step 3-6 should be conducted in the generator folder for AMR-to-Text Generation, and the translator folder for Syntax-based Machine Translation respectively. The default settings in this repo should reproduce the results in our paper.

3. Vocab & Data Preparation

cd generator/tranlator
sh prepare.sh # check it before use

4. Train

cd generator/tranlator
sh train.sh # check it before use

5. Test

cd generator/tranlator
sh work.sh # check it before use

# postprocess
sh test.sh (make sure --output is set)# check it before use

6. Evaluation

for bleu: use sh multi-bleu.perl (-lc)
for chrf++: use python chrF++.py (c6+w2-F2)
for meteor: use meteor-1.5 "java -Xmx2G -jar meteor-1.5.jar test reference -l en"
