Are We Really Making Much Progress? Bag-of-Words vs. Sequence vs. Graph vs. Hierarchy for Single- and Multi-Label Text Classification

This repository contains code to reproduce the results in our paper 'Are We Really Making Much Progress? Bag-of-Words vs. Sequence vs. Graph vs. Hierarchy for Single- and Multi-Label Text Classification', which is an extension to the paper 'Bag-of-Words vs. Graph vs. Sequence in Text Classification: Questioning the Necessity of Text-Graphs and the Surprising Strength of a Wide MLP' published in ACL 2022.

The goal of this study was to compare a simple WideMLP model with current state-of-art graph-based and sequential models. We split the repository into subfolders based on the different models (see folder structure).

Folder structure:

├── HiAGM                                # Code for HiAGM
├── Transformers                         # Code for transformer models (BERT & DistilBERT)
├── WideMLP                              # Overview WideMLP
│   ├── multilabel-processing            # Code for main WideMLP experiments reported in the paper
│   ├── sparse-multilabel-processing     # Code for further WideMLP experiments on Pubmed dataset
├── gMLP                                 # Code for gMLP/aMLP
├── multi_label_data                     # Used multi-label datasets in JSON format
├── multi_label_data_preprocessing       # Code to preprocess datasets into JSON format     
├── single_label_data                    # Used single-label datasets
└── README                               # Project structure overview

Every subfolder has a README with introductions on how to run the experiments.

The code for reproducing most single-label results can be found in following repositories:

MLP and TextGCN

Tranformers
