Earley algorithmus
WebOverview. Earley parsers are among the most general parsers out there, and they can parse any context-free language without restriction. Earley parsing algorithm is an … Webn, the Earley algorithm[4] constructs n+ 1 Earley sets: an initial set S 0, and a set S i associated with each input terminal x i. Elements of these sets are Earley items, each of which is intuitively an ‘in-progress’ production rule of the gram-mar. The Earley sets are constructed in such a way that S i contains all possible Earley items ...

WebThe Earley parser proceeds one input position at a time, keeping track of all the information that would needed to simulate the parsing threads. For each input position j, an Earley parser builds up a set of items I j representing the state of productions that might be used in the derivation. An Earley item has the form [A → β.γ, k].
WebA Pint-sized Earley Parser. Many people have said that convenient parser generation is a game-changing technology. In his talk To Trap a Better Mouse, Ian Piumarta suggested that the Earley algorithm is a good place to start because it handles full context-free grammars and is fairly trivial to implement.
