Unsupervised Morpheme Analysis -- Morpho Challenge 2010

**Table:** The obtained BLEU scores in the machine translation task for the submitted analysis in **Finnish**. Methods without authors are reference methods by the organizers. The types are: S = semi-supervised algorithm, P = unsupervised algorithm with supervised parameter tuning, U = fully unsupervised algorithm.
