Formal Grammar

Formal grammar is a set of rules that define a formal language. In the context of data science and artificial intelligence, formal grammar is used to define the syntax and structure of programming languages, as well as natural language processing. Formal grammars are used to generate and recognize strings of symbols that are valid in a given language. They are used in the design of programming languages, compilers, and interpreters. Formal grammars are also used in natural language processing to parse and analyze text. There are several types of formal grammars, including regular grammars, context-free grammars, and context-sensitive grammars. Each type of grammar has its own set of rules and restrictions, and is used for different purposes. Formal grammar is an important concept in data science and artificial intelligence, as it provides a foundation for the development of programming languages and natural language processing systems.
