3. Feature grammars, semantics (a) Consider the following context-free grammar: S + NP VP VP → VNP NP → he she | him | her → likes V Augment this grammar to become a unification-based (feature-based) grammar, by adding a 'case' feature, and constraints to enforce case agreement, to restrict the language to only those sentences that are correct English. You can use the notation used in the lectures or the notation of NLTK.

NAT Lang processing: Please explain in detail Consider a CFG representing a phrase structure grammar for a natural language such as English, including the following rule (the period is part of the rule): S -> NP VP . In this rule, S, NP, and VP are non-terminal symbols, but we will assume that the period is a terminal symbol specifically representing a period (as opposed to some other end-of-sentence marker). So, we can interpret this rule as stating that a sentence can have the form of a noun phrase followed by a verb phrase followed by a period. (To implement a parser for grammars with rules like this, the tokenizer would have to treat periods as separate tokens.) Assume that you need to convert this grammar to Chomsky normal form (CNF), perhaps with the CKY parsing algorithm in mind. Using the procedure discussed in class, show the rules that might result from the conversion.
