Percentages of words with more than 3 morphemes (>3 Morph.), surface segmentation (Surf.), canonical segmentation (Canon.), and without segmentation (NoSeg.), as well as the average number of morphemes per word (M./W.) and characters per word (Ch./W.).
by manual inspection, we identify five not mutually exclusive types of errors: Oversegmentation (Overseg.) arises when the number of morpheme boundaries in the prediction is higher than in the gold standard annotation.
