Mach Translat (2008) 22:101–152 DOI 10.1007/s10590-009-9051-z Morphological mismatches in machine translation Igor Mel’ˇcuk · Leo Wanner Received: 19 February 2008 / Accepted: 23 March 2009 / Published online: 13 May 2009 © Springer Science+Business Media B.V. 2009 Abstract This paper addresses one of the least studied, although very important, problems of machine translation—the problem of morphological mismatches between languages and their handling during transfer. The level at which we assume transfer to be carried out is the Deep-Syntactic Structure (DSyntS) as proposed in the Meaning- Text Theory. DSyntS is abstract enough to avoid all types of surface morphological divergences. For the remaining ‘genuine’ divergences between grammatical signi- fications, we propose a morphological transfer model. To illustrate this model, we apply it to the transfer of grammemes of definiteness and aspect for the language pair Russian–German and German–Russian, respectively.
