The distinction between operational and denotational semantics is an essential one, and it is necessary to have an understanding of this distinction.

This is a practice question from my Discrete Mathematical Structures course. Thank you.

Describe the approach of using axiomatic semantics to prove thecorrectness of a given program.

Please explain what you mean by "static semantics" below. Kindly provide some instances of static semantic norms that are difficult to build using BNF.

Explain the distinctions that exist between the different kinds of semantics, when and how they should be used, as well as the advantages and disadvantages that are associated with each sort of semantics.

If someone could provide me an example of "Semantic Augmentation" and explain the ideas of CFG (Context Free Grammar), I'd much appreciate it.

1. Use the algorithm described in class that takes a CFG and converts it into a CNF (Chomsky Normal Form) grammar that generates the same language as the original grammar, except possibly for the string A, to answer the following question. As part of your answer, you should say which variables are nullable, and you should give the appropriate grammar after each step of the algorithm. There are four steps. Give a CFG (context-free grammar) in CNF (Chomsky Normal Form) that generates the same language, except possibly for the string A, as the following grammar: SAB AB →bAa A → aaB bb

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"));…
