The lack of CG for Swedish is a problem. My suggestion would be to write one. To be a bit specific: To write the 100-or-so rules needed for removing the gross majority, say 80(?)% of the ambiguity. > What you're describing is gisting/translation for understanding; I can't > imagine gisting MT would be very useful for sv-nb/nn (and I suspect > people would use Google for that anyway). >From the Norwegian side, we cannot imagine the need for a sv-nb/nn gisting >system.

Yes, a production system (say, I want to translate a sv article to nn on Wikipedia) is a different matter. My experience from nn-nb translation is that time saving from post editing as compared to rewriting/translation lies around 80%. So yes, that can be a good idea. __But__ nb-nn lexicon and orthographic principles are the same, so more often than not unknown words will come out as free rides. For sv-nn/nb that will __not__ be the same (to the same extent), since both vocabulary and orthography deviates more. So, less free rides for unknown words. This implies that the transfer lexicon must be __much__ bigger than the nb-nn one in order to get the same good results as we have for nb-nn. The good news is that the making of such an enlarged transfer lexicon in part can be done automatically, and then manually post edited. >> >> (3) You make the two translators in the one pair.

This is also a possibility, yes.

Yes.

The best resource is the NoWaC corpus, it also has frequency lists, both for lemmata and for word forms. My final comment would be that the work will be 1 in the analysis/generation of Swedish 2 … and in the bidix. As for 1, we should look around in the Swedish language technology landscape and look for open resources, e.g. in Gothenburg (Aarne Ranta, also Språkbanken). As for 2, Lexin might be one resource. I am on Euralex in Oslo right now, and will ask around.
