Why is syntax important?

• Foundation for semantic analysis(on many levels of representation: semantic roles, compositional semantics, frame semantics)

Why is syntax insufficient?

• Syntax encodes the structure of language but doesn't directly address meaning.

• Syntax alone doesn't ground "grab" in an action to take in the world.

Lexical semantics

• Vector representation that encodes information about the distribution of contexts a word appears in

• Words that appear in similar contexts have similar representations(and similar meanings, by the distributional hypothesis).

• We can represent what individual words "mean" as a function of what other words they're related to(but that's still not grounding).
