Quiz 2 (CS1573) - NLP

  1. List 4 categories of knowledge about language that are required for human-like language understanding.
  2. What has Eliza contributed research-wise to natural language processing?
  3. Write a regular expression to match sentences where the first word of the sentence is a pronoun (I, you, he, she, it, we, they) and the next word is the correct present-tense form of "to be" (e.g., am, are ...). Thus your regular expression should match sentences like "She is happy." but should not match sentences like "She are happy."
