SPADE

Introduction

This repository contains the source code of our recent publication Spatial Dependency Parsing for Semi-Structured Document Information Extraction. The paper is accepted at Findings of ACL 2021.
SPADE♠️ (SPAtial DEpendency parsing) accepts 2D text (text segments and their xy-coordinates).
SPADE♠ generates the graph that represents semi-structured documents (such as receipts, name cards, invoices).

In the uploaded data.tar.gz, you can also find type0 data where the data is organized reflecting their original format. In this case, raw_data_input_type should be set to type0 and label is generated while loading the data.

Preprocessing

CORD

The preprocessed data and trained model is already included for CORD datset (type1).
To generate them from from (almost) raw data (type0), do bash scripts/preprocess_cord.sh

FUNSD

bash scripts/preprocess_funsd.sh

Model

Training

bash scripts/train_[task].sh
Takes around 4 days on 6 P40 gpus with DDP.
The best model is picked using dev set for cord.
For FUNSD task, use 'eary stopping' for the model validation. If the model is trained with uploaded config file with 6 P40, 2000-4000 epochs are recommended (some fluctuation in the final score is expected due to small size of the dataset depending on the random seed). Do not use the validation score for the model selection. It is dummy.

Evaluation

bash scripts/test_[task].sh

Prediction

bash scripts/predict_cord.sh
