WebThe parser presented in this thesis is based on Stuart Shieber's extensions of Earley's algorithm. This algorithm is further extended in order to incorporate traces and compound lexical items. Also, the algorithm is optimized by performing the subsumption test on restricted DAGs rather than on the full DAGs that are kept in the chart. Since the ... 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 ...
