GreekWikipedia

A Greek abstractive summarization dataset collected from the Greek part of Wikipedia, which contains 93,432 articles, their titles and summaries. This dataset has been used to train our best-performing model GreekWiki-umt5-base as part of our research paper:
Giarelis, N., Mastrokostas, C., & Karacapilidis, N. (2024) Greek Wikipedia: A Study on Abstractive Summarization.
For information about dataset creation, limitations etc. see the original article.

Supported Tasks and Leaderboards

This dataset supports:

Text summarization: Given the text of an article, a text generation model learns to generate an abstractive summary.
Title Generation: Given the text of an article, a text generation model learns to generate a post title.

Languages

All articles are written in Greek.
