The ability to automatically summarize news articles has become increasingly important due to the vast amount of information available online. Together with the rise of chatbots , Natural Language Processing (NLP) has recently experienced a tremendous amount of development. Despite these advancements, the majority of research is focused on established well-resourced languages, such as English. To contribute to development of the low resource Slovak language, we introduce SlovakSum, a Slovak news summarization dataset consisting of over 200 thousand news articles with titles and short abstracts obtained from multiple Slovak newspapers. The abstractive approach, including MBART and mT5 models, was used to evaluate various baselines. The code for the reproduction of our dataset and experiments can be found at https://github.com/NaiveNeuron/slovaksum
