CRFSuite does not support n-best output. The decoder algorithm is Viterbi which appears to not too difficult to make it n-best (especially for short sequences).

Did you manage to get meaningful n-best outputs with Wapiti on your data? I looked at it a while ago and realized that on my data n-best outputs not always make sense (NER).

How about looking at marginal probabilities for all possible labels in a given position (that functionality exists in the Python wrapper as pycrfsuite.Tagger.marginal() so I presume also in the CFRSuite itself) and picking the best n values?

@ZmeiGorynych Unfortunately marginals is not enough to compute the n-best sequence taggings.
