Formal Grammars

Formal grammars are sets of rules that define the structure of a language. In the context of data science and artificial intelligence, formal grammars are used to define the syntax and structure of programming languages, as well as natural languages. They are used in natural language processing to parse and analyze text, and in programming language design to ensure that code is written in a consistent and understandable way. Formal grammars are often represented using mathematical notation, such as Backus-Naur Form (BNF) or Extended Backus-Naur Form (EBNF). These notations define the rules for constructing valid sentences in a language, and can be used to generate parsers that can automatically analyze and understand text or code.
