This is a version of squad derived from SQuAD v2 on which we did the following changes:
def remove_long_answers(example): #MAP
new_answers = {'text':[], 'answer_start':[]}
answers_set = set()
for text, start in zip(example['answers']['text'], example['answers']['answer_start']):
if len(text.split()) > 10:
continue
else:
if (text, start) not in answers_set:
new_answers['text'].append(text)
new_answers['answer_start'].append(start)
answers_set.add((text, start))
example['answers'] = new_answers
return example
def filter_whitespace(example): #MAP
example['context'] = ' '.join(example['context'].split())
example['question'] = ' '.join(example['question'].split())
example['answers']['text'] = [' '.join(answer.split()) for answer in example['answers']['text']]
return example
def checks(example): #FILTER
if example['answers']['text'] == []:
return False
if len(example['question'].split()) > 35:
return False
if len(example['question'].split()) < 3:
return False
return True |
