Questions

  1. Q1

    1. a)

      Describe the process of building a simple Markov model for predicting the next word in a sentence with the help of example.

      [6]
    2. b)

      Suppose you have a text corpus of 10,000 words, and you want to build a bigram model from this corpus. The vocabulary size of the corpus is 5,000. After counting the bigrams in the corpus, you found that the bigram “the cat” appears 50 times, while the unigram “the” appears 1000 times and the unigram “cat” appears 100 times. Using the add-k smoothing method with k=0.5, what is the probability of the sentence “the cat sat on the mat”?
