I don't know if this means that they excluded the two major forms of Norweigian 'nn' and 'nb' or if they mapped everything labelled as either to 'no'. I don't know if they added spaces to languages that don't really use white space like Thai and Japanese.
Edit: The number of sentences are in supplemental figure 7 and Norweigian has almost as many examples as Danish so the data is there, I'm just not sure which kind of Norweigian we are talking about.
