With respect to translation quality, whereas Logomedia and Reverso could hardly be distinguished when it came to numbers of translations of sentences adjudged as intelligible and syntactically correct, if we consider those translations considered unintelligible by our human evaluators, about twice as many translations produced by chunks derived from Reverso were unintelligible compared to those produced by Logomedia.
consider the examples in (45): (45) Input: an old story in common System B: une vieille histoire dans commun System combination Bc: une vieille histoire en commun the optional PP in common was mistranslated by system B as dans commun, but when knowledge from system c is added to that of system B, the improved translation en commun is generated.
