Norsource is an HPSG-based grammar of Norwegian developed at NTNU.

A. A ‘Grammar Sparrer’, as described in Hellan et al. 2013, accessed at http://regdili.hf.ntnu.no:8081/studentAce/parse. This is a construct along the lines of Bender et al. 2004, and Suppes et al. 2014, falling within the overall initiatives described in Heift and Schultze 2007, where specific types of grammatical mistakes are accommodated by ‘mal-rules’ in an extended ‘mal’-version of the grammar, and parses involving such mal-phenomena are reported to the user as tutoring instructions. This system has been running as a webdemo since 2011.

B. A Multilingual Valence repository, based on NorSource and three further LKB grammars: The Spanish Resource Grammar, the Bulgarian grammar BURGER, and a grammar of Ga. Information from these grammars is imported in a uniform format into the repository. In essence, the valence code used in verbal lexical types is expanded to alternative and more easily inspectable formats, and the verb lexicons of the languages involved are imported into a database organized according to the newer codes, and searchable in terms of these codes. See web access at http://regdili.hf.ntnu.no:8081/multilanguage_valence_demo/multivalence, and for description, Hellan and Bruland 2013, and Hellan et al. 2014.

C. An initial version of a POS-tagger of Norwegian, reflecting the lexical inventory of the grammar, which amounts to appx. 85000 lexical entries, and a large number of proper names of various categories. The tagger currently offers all available POS-alternatives for a given word. See web access at http://regdili.hf.ntnu.no:8081/webtagger/tagger.
