# GreekWikipedia |
|
|
|
A Greek abstractive summarization dataset collected from the Greek part of [Wikipedia](https://el.wikipedia.org/), which contains 93,433 articles, their titles and summaries. |
|
This dataset has been used to train our best-performing model [GreekT5-umt5-base-greekwikipedia](https://huggingface.co/IMISLab/GreekT5-umt5-base-greekwikipedia/) as part of our research article: |
