roberta-large-question-classifier

This model classifies questions according to the question-type ontology defined in following paper: Controllable Open-ended Question Generation with A New Question Type Ontology (Cao & Wang, ACL-IJCNLP 2021). It is a fine-tuned roberta-large on the open_question_type dataset. It achieves the following results on the test set:
