This means that the runtime is not ...

Earley Parsing Explained - Loup Vaillant
WebJul 16, 2024 · The Earley algorithm is naturally task-based, but is difficult to parallelize because of dependencies between the tasks. We present the LATE algorithm, which uses additional data structures to maintain information about the state of the parse so that work items may be processed in any order.

WebJan 9, 2012 · An Earley parser will parse any context-free language given just a set of rules. The price is significant execution time: O (N^3), where N is the length of the input. If N is large (as it is for many parseable entities), you can end with Very Slow parsing. And this is the reason for a parser generator (PG). If you parse a lot of documents, Slow ... first they killed my father dvd
