KaLM at SemEval-2020 Task 4: Knowledge-aware Language Models for Comprehension And Generation

Understand

This paper presents our strategies in SemEval 2020 Task 4: Commonsense Validation and Explanation.

• We propose a novel way to search for evidence and choose the different large-scale pre-trained models as the backbone for three subtasks.
• The results show that our evidence-searching approach improves model performance on commonsense explanation task.
• Our team ranks 2nd in subtask C according to human evaluation score.
