Abstract

We present a parsing technique which is a hybrid of Earley's method and the LR(k) methods. The new method retains the ability of Earley's method to parse using arbitrary context-free grammars. However, by using precomputed LR(k) sets of items, we obtain much faster recognition speeds while also reducing memory requirements.

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
