N2 - The detection of subjectivity in natural language plays a crucial role in various applications, such as sentiment analysis, fake news detection, and fact-checking systems. However, effectively and accurately detecting subjectivity across different languages presents substantial challenges due to linguistic variations and cultural nuances. This paper describes the system we developed for 2023 CheckThat! Lab Task 2 on subjectivity detection using a multilingual model, mDeBERTaV3-base. In particular, we use a common multilingual dataset to fine-tune multiple mDeBERTaV3-base models using language specific development data to specialize the systems towards a target language and reduce the impact of the class imbalance in the training data. In this way, we managed to rank first in German, Italian and Turkish, second in Arabic and over a Multilingual dataset, and third in English.
