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

While Large Language Models (LLMs) have demonstrated considerable potential in advancing natural language processing in dialect-specific contexts, their effectiveness in these settings has yet to be thoroughly assessed. This study introduces a case study on Šariš, a dialect of Slovak, which is itself a language with fewer resources, focusing on Machine Translation and Common Sense Reasoning tasks. We employ LLMs in a zero-shot configuration and for data augmentation to refine Slovak-Šariš and Šariš-Slovak translation models. The accuracy of these models is then manually verified by native speakers. Additionally, we introduce ŠarišCOPA, a new dataset for causal common sense reasoning, which, alongside SlovakCOPA, serves to evaluate LLM’s performance in a zero-shot framework. Our findings highlight LLM’s capabilities in processing low-resource dialects and suggest a viable approach for initiating dialect-specific translation models in such contexts.
