Semantic analysis

Semantic analysis is basically focused on the meaning of the NL. Its definition, various elements of it, and its application are explored in this section.

Now let's begin our semantic journey, which is quite interesting if you want to do some cool research in this branch.

What is semantic analysis?

Semantic analysis is generating representation for meaning of the NL. You might think, if lexical analysis also focuses on the meaning of the words given in stream of text, then what is the difference between semantic analysis and lexical analysis? The answer is that lexical analysis is based on smaller tokens; its focus is on meaning of the words, but semantic analysis focuses on larger chunks. Semantic analysis...
