Lexical Issues in Dealing with Semantic Mismatches and Divergences
James A. Barnett, Elaine A. Rich · 1993
In this paper, we address the question, ’~/hat types of MT divergences and mismatches must be accommodated in the lexicon? In our work, we have focused on the treatment of divergences and mismatches in an interlingual (as opposed to a tranfer-based) MT system. In such systems, one uses monolingual lexicons for each of the language under consideration, so divergences and mismatches are not handled as explicitly as they must be in transfer-based systems that rely on bilingual lexicons. In an interlingual system, these issues become issues in NL generation into the target language. Divergences and Mismatches Two kinds of problems can occur as a result of a divergence [Dorr 90] or a mismatch [Kameyama 91]. The first is the relatively simple case, in which there is a lexical gap, i.e., a straightforward attempt to render a concept that was mentioned in the source language fails to find the required word. When this happens it is clear that there is a problem, although it is less clear what to do about it. Example: English know German wissenlkennen
