# GreekReddit |
|
|
|
A Greek topic classification dataset collected from Greek subreddits, which contains 6,534 posts, their titles and topic labels. |
|
This dataset has been used to train our best-performing model [Greek-Reddit-BERT](https://huggingface.co/IMISLab/Greek-Reddit-BERT) as part of our research article: |
