Parsing context-free grammars

Parsing context-free grammars. Context-free grammars specify structure, not process. There are many different ways to parse input in accordance with a given context-free grammar. We will review a top-down parsing algorithm a bottom-up parsing algorithm We will present the Earley algorithm.
