Question 2

+3 marksOne correct option

In stochastic POS tagging, why is it necessary to calculate both individual word probabilities and tag sequence probabilities?

  1. A

    Individual word probabilities are sufficient for accurate tagging, and tag sequence probabilities are redundant.

  2. B

    Individual word probabilities are only used for rare words, while tag sequence probabilities are used for common words.

  3. C

    Tag sequence probabilities help in determining the most likely sequence of tags, while individual word probabilities provide local context.

  4. D

    Both probabilities are used to reduce the computational complexity of the tagging process.

Correct answer

  • C

    Tag sequence probabilities help in determining the most likely sequence of tags, while individual word probabilities provide local context.
