Two approaches to grammar modeling
Constituency grammar [Martin, Jurafsky, 2000]
Phrase structure organizes words into nested constituents
Dependency grammar [Martin, Jurafsky, 2000]
Dependency structure shows which words depend on (modify or are arguments of) which other words.

TBD
Exercise 4.1
Construct constituency and dependency trees for the sentences:
- "Susan wants to marry Lary."
- "They saw a man with the telescope."
- "Why do we say that the earth moves around the sun?"
