# 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](https://aclanthology.org/2021.acl-long.502/) (Cao & Wang, ACL-IJCNLP 2021). |
|
It is a fine-tuned [roberta-large](https://huggingface.co/roberta-large) on the [open_question_type](https://huggingface.co/datasets/launch/open_question_type) dataset. |
|
It achieves the following results on the test set: |
