Tagset
The Oslo-Bergen tagset is mostly based on the Norwegian Reference Grammar (Norsk Referansegrammatikk, ed. Jan Terje Faarlund, Svein Lie and Kjell Ivar Vannebo 1997) - both in terms of grammatical categories and the names of the categories. This means, for example, that all words that are inflected for degree, are regarded as adjectives - even if the words have traditionally been regarded as adverb (eg. ofte 'frequently'). Furthermore, all the traditional place adverbs such as der 'where', bortenfor 'beyond', etc. are regarded as prepositions.
