Semi-automatic grammar recovery

摘要

We propose an approach to the construction of grammars for existing languages. The main characteristic of the approach is that the grammars are not constructed form scratch but they are rather recovered by extracting them form language references, compilers and other artifacts. We provide a structured process to recover grammars including the adaptation of raw extracted grammars and the derivation of parsers. The process is applicable to possibly all existing languages for which business critical applications exist.
