Abstract: Studying people’s satisfaction with social media is vital to understanding the users’ needs. Nowadays, textual hotel reviews are used to evaluate the hotel’s e-reputation. In this context, we are interested in Aspect Category Detection (ACD) as a subtask of aspect-based sentiment analysis. This task needs to be investigated through multi-label classification, which is more challenging, in natural language processing, than single-label classification. Our study leverages the potential of transfer learning with the pre-trained AraBERT model for contextual text representation. We are based on the Arabic SemEval-2016 data set for hotel reviews. We propose a specific preprocessing for this Arabic reviews dataset to improve the performance. In addition, as this data suffers from an imbalanced distribution, we use a dynamically weighted loss function approach to deal with imbalanced classes. The carried-out results outperform the pioneering state-of-the-art of the Arabic ACD with an F1 scor e of 67:3%. (More)
