 # GreekT5 (umt5-base-greeksum)
 
 A Greek news summarization model trained on [GreekSum](https://github.com/iakovosevdaimon/GreekSUM).  
-This model is part of a series of models trained as part of our research [arxiv_paper_title](arxiv_link).  
-The proposed models were trained and evaluated on the same dataset against [GreekBART](https://arxiv.org/abs/2304.00869).
