2 views of linguistic structure

Constituency

  • Phrase structure orgnizes words into nested constituents
  • How do we know what is a constituent?
    • Distribution: a constituent behaves as a unit that can appear in different places
    • Substitution, expansion, pro-forms
    • Coordination, regular internal structure, no intrusion, fragments, semantics

Dependency

  • Dependency structure shows which words depend on(modify or are arguments of)which other words.
