- The concept of "semantic augmentation" is defined and applied to CFG (Context Free Grammar) rules.Explain the two grammar characteristics that prohibit them from beingused as the basis for a top-down parser.The concept of "semantic augmentation" for CFG (Context Free Grammar) rules is defined and illustrated.
- Explain the phases that NLP follows with Parsing examples in Grammar?Label the following statement as True (T) or False (F): The following context-free grammar is in Chomsky normal form: S → XY | XZ X → XX | XY | aa Y → YY | b Z → ZX | εPlease don’t copy and paste other solutions. Suppose that in some programming language numbers are restricted as follows: (a) a number may be signed or unsigned. (b) the value field consists of two nonempty parts, separated by a decimal point. (c) there is an optional exponent field. If present this field must contain the letter e, followed by a signed two-digit integer. Design a grammar for the such numbers in this programming language
