  ## Model description
  
  A question type classification model based on multilingual BERT.
  
  The question type classifier takes as input the question, and returns a label that distinguishes between boolean and short answer extractive questions. 
  
  The model was initialized with [bert-base-multilingual-cased](https://huggingface.co/bert-base-multilingual-cased) and fine-tuned on the answerable subset of [TyDiQA](https://huggingface.co/datasets/tydiqa) train questions. 
  
  ## Intended uses & limitations
  
  You can use the raw model for question classification. Biases associated with the pre-existing language model, bert-base-multilingual-cased, may be present in our fine-tuned model, tydiqa-boolean-question-classifier.  
  
  ## Usage
  
  You can use this model directly in the the [PrimeQA](https://github.com/primeqa/primeqa) framework for supporting boolean question in reading comprehension as in this [example](https://github.com/primeqa/primeqa/tree/main/examples/boolqa).
