The LKB system is a grammar and lexicon development environment for use with constraint-based linguistic formalisms. The LKB software is distributed by the LinGO initiative, a loosely-organized consortium of research groups working on unification-based grammars and processing schemes. The download page for the LKB system and other available LinGO software and grammars is http://lingo.stanford.edu/ftp.

The LinGO English Resource Grammar (with associated lexicons and so on) may be downloaded from http://lingo.stanford.edu/ftp as erg.tgz. Note that it requires at least 250 MBytes of RAM to run with the LKB. No documentation for the ERG is available at this time (other than the source file comments).

The LKB system includes a tactical generation capability.

The LKB system is Open Source and there is no registration process.
