transcriptions of each hit, but also the video with
audio.

There are several other ways of showing the
results. One very useful one is the map view
(using Google Map technology). It shows the
phonetic variations of one orthographic search.
This is a very easy and enlightening way of
viewing isoglosses.
We illustrate with Figure 6. Here we have
simply looked up the word ikke 'not' in
Norwegian. There are more than 30 000 hits in
the corpus, and obviously impossible to quickly
make a manual overview. But the map approach
helps us. We have chosen to display three types
of the phonetic variants on the map:
1) the versions pronouns with a fricative or
affricate /ç,ʃ/ instead of the word-internal stop
(red markers), for example: /iʃe/.
2) those that have fricatives and affricates
followed by a nasal (yellow markers), for
example: /inçe/.
3) those that are pronounced with the stop (black
markers), for example: /ike/.
There are many more possibilities with regard to
presentation of results, as well as results
handling, and downloading.

8. Conclusion
The Nordic Dialect Corpus shows the
importance of involving the end users in the
development of a corpus. In our case, many of
the involved linguists were not experienced
corpus users beforehand, but could still deliver
highly valuable input regarding what would be
desirable features of the corpus. In the end, that
has led to a highly advanced tool for linguistic
research.
