A bottom-up adaptation of earley's parsing algorithm

Part of the Lecture Notes in Computer Science book series (LNCS, volume 348)


in this paper we have described a new, bottom-up, parsing algorithm, derived from the standard Earley's algorithm. It is easier to understand and more efficient, thanks to the precomputation of some closure relations and to the minimization of the number of items that it computes, and yields an improved practical efficiency and a better error explanation capability which make it well adapted to be the parsing system of many experimental environments.
