Earley parser

The Earley parser is a method used in computer science to analyze whether a sentence or sequence follows a specific grammar or set of rules. It works by gradually building possible interpretations, keeping track of what parts of the sentence have been recognized, what is expected next, and where errors might occur. It’s efficient for parsing complex or ambiguous structures, especially in natural language processing and programming languages. Essentially, it systematically explores all ways the input could fit the rules, helping computers understand or validate sentences accurately.
