Code for Mitigating Data Sparsity for Short Text Topic Modeling by Topic-Semantic Contrastive Learning (EMNLP 2022)

Check our latest topic modeling toolkit TopMost !

EMNLP 2022

Usage

1. Prepare Environment

python==3.7
pytorch==1.7.1
scipy==1.7.3
scikit-learn==0.23.2
pyyaml==6.0

2. Training

Training without data augmentation:

python run.py --data_dir data/${dataset} --model TSCTM --num_topic {number of topic}

Training with data augmentation:

python run.py --data_dir data/${dataset} --model TSCTM_aug --num_topic {number of topic}

After training, outputs are in ./output/{dataset}/, including topic words, topic distributions of short texts, and topic-word distribution matrix.

3. Evaluation

topic coherence: coherence score

topic diversity:

python utils/TU.py --data_path {path of topic word file}
