  We present our works on SemEval-2021 Task 5 about Toxic Spans Detection. This
task aims to build a model for identifying toxic words in whole posts. We use
the BiLSTM-CRF model combining with ToxicBERT Classification to train the
detection model for identifying toxic words in posts. Our model achieves 62.23%
by F1-score on the Toxic Spans Detection task.
