UoB at SemEval-2021 Task 5: Extending Pre-Trained Language Models to Include Task and Domain-Specific Information for Toxic Span Prediction
Erik Yan, Harish Tayyar Madabushi · 2021
Toxicity is pervasive in social media and poses a major threat to the health of online communities.The recent introduction of pre-trained language models, which have achieved stateof-the-art results in many NLP tasks, has transformed the way in which we approach natural language processing.However, the inherent nature of pre-training means that they are unlikely to capture task-specific statistical information or learn domain-specific knowledge.Additionally, most implementations of these models typically do not employ conditional random fields, a method for simultaneous token classification.We show that these modifications can improve model performance on the Toxic Spans Detection task at SemEval-2021 to achieve a score within 4 percentage points of the top performing team.
