4 The Project Context

5 The HPSG Grammar Network

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

12 Other Projects  Financed Projects LOGON -  Not yet funded NorDeTrans Norwegian- German Translation Project

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.
