This paper describes our system for SemEval-2021 Task 5 on Toxic Spans Detection.We developed ensemble models using BERT-based neural architectures and post-processing to combine tokens into spans.We evaluated several pre-trained language models using various ensemble techniques for toxic span identification and achieved sizable improvements over our baseline fine-tuned BERT models.Finally, our system obtained a F1-score of 67.55% on test data.
