SKAM at SemEval-2023 Task 10:Linguistic Feature Integration and Continuous Pretraining for Online Sexism Detection and Classification

Sexism has been prevalent online. In this paper, we explored the effect of explicit linguistic features and continuous pretraining on the performance of pretrained language models in sexism detection. While adding linguistic features did not improve the performance of the model, continuous pretraining did slightly boost the performance of the model in Task B from a mean macro-F11 score of 0.6156 to 0.6246. The best mean macro-F1 score in Task A was achieved by a finetuned HateBERT model using regular pretraining (0.8331). We observed that the linguistic features did not improve the model’s performance. At the same time, continuous pretraining proved beneficial only for nuanced downstream tasks like Task-B.</p
