The LKB system is a grammar and lexicon development environment for use with unification-based linguistic formalisms. While not restricted to HPSG, the LKB implements the DELPH-IN reference formalism of typed feature structures (jointly with other DELPH-IN software using the same formalism).

The primary documentation on the LKB is provided by the book Implementing Typed Feature Structure Grammars. Excerpts from the book provide an tour of the LKB (although see LkbInstallation for revised installation instructions) and the user manual.

These pages are intended to provide documentation for aspects of the LKB not covered by the book, including recent developments. The use of a wiki forum is intended to enable LKB developers and users alike to contribute to the available on-line documentation. If you are new to the wiki paradigm, please first familiarize yourself with the etiquette and formatting guidelines, then create a wiki user name for yourself, register on the server, and start editing pages.


The LKB has been in active use since around 1991, with a substantially new version in use from about 1997. These pages include documentation on the following topics:

Other pages can be found by entering 'Lkb' in the wiki search box. Please check this site regularly to see the LKB wiki grow. Or, if you are a knowledgeable LKB user, consider some volunteer work in creating up-to-date on-line documentation.


Small sample grammars are downloadable as described in LkbInstallation. Larger scale resources which are freely downloadable include:


Projects which have made extensive use of the LKB include:
