Earley algorithm

WebA GLR parser (GLR standing for "Generalized LR", where L stands for "left-to-right" and R stands for "rightmost (derivation)") is an extension of an LR parser algorithm to handle non-deterministic and ambiguous grammars. The theoretical foundation was provided in a 1974 paper by Bernard Lang (along with other general Context-Free parsers such as GLL). It … http://www.cse.unt.edu/~tarau/teaching/NLP/Earley%20parser.pdf

Think of chart entries as sitting between words in the input string, keeping track of states of the parse at these positions ! For each word position, chart contains set … Webthe Earley algorithm. Since there is no additional functionality needed beside that already discussed, we make a Chart array for the evolving set of chart states, rather than making … WebEssentially, instead of storing a sequence of sets of items like in the original algorithm, the modified algorithm just stores pointers back to sets of reachable items. The worst-case run time performance of the Earley parsing algorithm is cubic in the length of the input, but for large classes of grammars it is linear. haldrath\u0027s march
