Dear teachers,

Could you please explain the solution of the 3rd question of quizz 2 ? 

Moreover, in Q11, "PoS tagging aims to suppress lexical variability of words" is considered false but POS tagging can be used for lemmatization which aims to suppress the lexical variability of words. I wonder why it is false.

Best regards,

Ali

Sure:
P(banana) = P(bana) * P(n|ana) * P(a|nan)
          = P(bana) * P(anan) / P(ana) * P(a|nan)

P(ananas) = P(anan) * P(a|nan) * P(s|ana)
          = P(anan) * P(a|nan) * P(anas) / P(ana)

As you say: 

  1. POS tagging can be used for lemmatization
    (but POS itself does NOT suppress the lexical variability of word)
  2. lemmatization aims to suppress the lexical variability of word
