Grammar Study Note, Part One

  1. Pos tagging indicates the property of the word itself.
  2. Dependency tagging indicates the function (or relative information) of the word.
  3. Both N-gram model and PCFG model assumes the a Markov property and then applies the conditional probability.

Dependency Grammar Notions

  1. Subject-Predicate relationship
    subject: The person or thing about whom the statement is made
    predicate: The purpose of the predicate is to complete an idea about the subject

Part of Speech Tagging

  1. Ambiguity:
    Local Preference -> The probability of a part-of-speech tag for a specific word in the vocabulary
    Contextual Preference -> The probability of a part-of-speech tag for a specific word in given context.
