Martin,

Here are my comments. As I see it, there is an improvement for 13 words
and 5 words are worse. 

In all the 5 cases the s is a genitive s. I would also belive that many
of the 13 words have a higher frequency in normal text.

Jan,

I apologise for taking so long to get back to the stemming work, but I
have been busy with other things. You suggested (13 Jan) removing k from
define_s_ending in the Norwegian stemmer. In the sample vocabulary about
one word per thousand is affected by this. Here is the list:

I think I will add your suggestion, since the forms marked + (I believe)
are improved by the rule, the forms marked 0 made worse. The forms
marked ? I cannot interpret.

I wonder if you could comment on this list as a native speaker of
Norwegian?
