Fundamental Issue
When encountering a garden-path, how humans correct temporary syntax tree?
Even today, this is not really
well-understood
Syntactic Ambiguity
Syntactic Ambiguity = Situation that there is more than one syntax tree for the same sentence
They discuss the violence on TV.
They discuss the violence on TV.
Usage for Linguistic Experiments
Tom painted the wall with cracks.
Tom saw the man with a telescope.
Tom painted the wall with a brush.
You can obtain strength of collocation:
Tom saw the man with a telescope.
