6. LKB - the platform The LKB system – open source software 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.

13. LOGON is a cooperation project between groups at the universities in Oslo, Bergen and Trondheim, one aim of which is the development of a machine translation demonstrator for Norwegian-to-English, using the frameworks LFG and HPSG in the 'deep processing' aspects. The project period is Jan 03 to Dec 06.
