The "Norwegian HPSG Resource Grammar" - NorSource - was started in 2002, using the LKB platform and version 0.1 of the HPSG Grammar Matrix. Its development was strongly furthered by the NTNU participation in the DeepThought project, in the course of which the grammar reached a medium size coverage, and could import a large lexicon. With domain specific enrichments pertaining to the semantics of locative and directional expressions, the grammar was used in a small end-to-end demo called "TrailFinder", extracting mountain hike information from tour descriptions (to appear in Proceedings of CLIN 2004). In the setting of a reasonably broad coverage of phenomena, exploration of how to encode various types of semantic specification remains a main focus.
