Questions:
1- What does CCG stand for?
2- Using following CCG grammar rules and lexicons, try to parse and represent the following sentence: (optional)
Sentence for parsing: “Pennsylvania neighbors New York.”
rules:
New York ˫ NP : new _york
Pennsylvania ˫ NP : pennsylvania
neighbors ˫ S\NP/NP : λ x λy.neighbors(x, y)

Y : g X\Y : f =⇒ X : f(g)
3- What is the function of “relation-count” attribute in Sentence Retrieval Engine algorithm and how it does manage to do that function?
4- What are two criteria for Assessor algorithm in assessing sentences?
5- What are feasible and infeasible questions? Explain how infeasible questions affect the performance of FreeParser.
