NLP: CIA 2

BLEU stands for Bilingual Evaluation _______

Formula to calculate Precision

• Precision = True Positives + False Positives
• Precision = True Positives / Total Samples
• Precision = True Negatives / (True Negatives + False Negatives)
• Precision = True Positives / (True Positives + False Positives)

Formula to calculate Recall

• Recall = True Positives / Total Samples
• Recall = False Positives / (False Positives + True Negatives)
• Recall = True Positives / (True Positives + False Negatives)
• Recall = True Negatives / (True Negatives + False Positives)

Which of these is NOT an evaluation metric of a language

• n Gram

• BLEU

• PPL

• F1 Score

Which of these is a correct example of Bigram model

• A correct example of a Bigram model is: ('I', 'love') and ('love', 'programming').
• ('love', 'I') and ('programming', 'love')
• ('I', 'love', 'programming')
• ('I', 'programming') and ('programming', 'I')

Pragmatic ambiguity refers to
