Examples of pairs that were wrongly labeled as cognates by the classifier relying on orthographic information and that are correctly labeled as non-cognates by the combined classifier are: affects-effecten, unlocking-blokkering, investments-instrument, slit-gesplit, provide-profielen, brazier-branden, might-high, where-wateren.
