Consider the following PCFG: S NP VP [1.0] NP Noun [0.6] | Pronoun [0.4] VP

Question:

Consider the following PCFG:

S → NP VP [1.0]

NP → Noun [0.6] | Pronoun [0.4]

VP → Verb NP [0.8] | Modal Verb [0.2]

Noun → can [0.1] | fish [0.3] | . . .

Pronoun → I [0.4] | . . .

Verb → can [0.01] | fish [0.1] | . . .

Modal → can [0.3] | . . .

The sentence “I can fish” has two parse trees with this grammar. Explain the semantic difference between the two. Show the two trees, their prior probabilities, and their conditional probabilities, given the sentence.
