This algorithm is similar to Top-down parsing. It can handle left-recursion, and it doesn't need CNF. It fills in a chart in the left to right manner. Consider an example that illustrates parsing using the Earley chart parser: >>> import nltk >>> nltk.parse.earleychart.demo (print_times=False, trace ...

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.
