AT&T GRM Library, a set of tools for constructing grammars

The GRM Library (Grammar Library) is a set of general-purpose software tools for constructing, modifying, and compiling grammars. The GRM functionalities include:

- Context-Dependent Rules: compilation of weighted context-dependent rules into weighted finite-state transducers defined over general semi-rings.

- Context-Free Grammars: approximation and compilation of weighted context-free grammars into weighted automata. Dynamic modification of compiled context-free grammar automata.

- Text and Grammar Processing Utilities: general text and grammar processing utilities (e.g. construction of weighted suffix automata, counting sequences appearing in weighted automata, construction of local grammars).

- Statistical Language Models: creation and modification of statistical language models derived from input text or input weighted automata.
