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.

Need step by step details solution
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.
I need help with my context free language. It needs to do the following 1. Developing a language model based on the context-free grammar: Use the context-free grammar to develop a language model that can be used to generate coherent and grammatically correct sentences in American English.2. Incorporating semantic information into the context-free grammar: Expand the context- free grammar to incorporate semantic information, such as word meaning and context, to generate more meaningful sentences in American English. here is my Java code import java.util.*;import java.util.stream.Collectors; public class CFG { private static Map<String, List<String>> rules; public static void main(String[] args) { rules = new HashMap<>(); initializeGrammarRules(); String sentence = generateSentence("S"); System.out.println(sentence); } private static void initializeGrammarRules() { rules.put("S", Arrays.asList("NP VP"));…
