> I tried to execute POSTaggerCrossValidator with the -ngram parameter and it caused a UnsupportedOperationException.
> Sometimes it is interesting for some training tools to pre-process the corpus to artifacts before training, for example dictionaries.
> CrossValidationPartitioner.TrainingSampleStream should support the reset operation to allow this functionality.
> Does anybody know why it does not support resetting?
