Overview

Graph Neural Topic Model (GNTM)

This is the pytorch implementation of the paper "Topic Modeling Revisited: A Document Graph-based Neural Network Perspective"

Requirements

  • Python >= 3.6
  • Pytorch == 1.6.0
  • torch-geometric == 1.7.0
  • torch-scatter == 2.0.6
  • torch-sparse == 0.6.9

Dataset

The links of the datasets can be found in the following:

The Glove word embeddings can be download from theis link.

The datasets and word embedings should be placed with the guide of the paths in the settings.py.

Usage

Before training GNTM, we first need to preprocess the data by the following scripts (need adjust some parameters based on the description in our paper for different datasets.):

cd dataPrepare
python preprocess.py
python graph_data.py

Example script to train GNTM:

python main.py \
--device cuda:0 \
--dataset News20 \
--model GDGNNMODEL \
--num_topic 20 \
--num_epoch 400 \
--ni 300  \
--word \
--taskid 0 \
--nwindow  3

Here,

  • --dataset specifies the dataset name, currently it supports News20, TMN, BNC and Reuters for 20 News Group, Tag My News, British National Corpus and Reuters, respectively.
  • --device represents computation device, such as cpu or cuda:0.
  • --model represents the used model, GDGNNMODEL is corresponding to GNTM
  • --num_topic represents the number of topics.
  • --num_epoch represents the maximized number of training epochs.
  • --ni represents the dimension of word embeddings.
  • --taskid is corresponding to the random seed.
  • --nwindow represents the window size to construct dpcument graphs.
