Source code for "A Double-Graph Based Framework for Frame Semantic Parsing" @ NAACL 2022

Overview

TL;DR: A framework for frame semantic parsing aims to utilize double-graph structure to inject knowledge into parsing and strengthen interacrions between arguments.

Paper Link: A Double-Graph Based Framework for Frame Semantic Parsing, TODO: this is early version of our paper, we will replace it with camera-ready version soon.

We find ontological frame knowledge can contribute to frame semantic parsing by both intra-frame and inter-frame reasoning. To make use of it, we build FKG (Frame Knowledge Graph) on definitions of FEs, frame relations and FE mappings. Besides, We regard frame semantic parsing as a process to add nodes in FSG (Frame Semantic Graph) incrementally, which can strengthen relations beween arguments and interactions of subtasks in frame semantic parsing.

Requirements

pandas == 1.4.1
pytorch == 1.11.0
scipy == 1.8.0
stanza == 1.3.0

How to Run Our Code?

Datapreprocess

You can get some data files from scratch, we will also provide links to download remaining data files.

TODO: replace them with one single shell data_preprocess.sh

Run data_preprocess.py to get data_instance_dic and word/lemma vectors from GloVe.

python data_preprocess.py

Then run dep_parsing.py to build dependency trees for each sentence. This will modify data_instance_dic produced by data_preprocess.py, and we DO NOT parse exemplar_instance_dic because it will take a lot time. You can modify dep_parsing.py to parse exemplar_insrtance_dic if you want to pretrain on exemplar sentences.

python dep_parsing.py

Run build_fe_name_dict.py to get fe_label_to_name.npy which stores a dict to map FE id to their name.

python build_fe_name_dict.py

Run parse_fe_xml.py and rel_graph_construct.py to build adj matrix for FKG.

pretraining on exemplar sentences

python pretrain.py --save_model_path [prefix of your model path, e.g. ../model/pretrain_] --epoch 30

Fine-tuning on train instances:

python train.py --pretrain_model_path ../model/pretrain_30.bin --lr 6e-5 --save_model_path [path where you save fine-tuned model]

Train

python train.py --save_model_path [path where you save trained model]

For more details of arguments, see config.py

Evaluate

python train.py --mode test --batch_size 2 --save_model_path [path where you save trained model]
