Research on the Transformation of Ba-Construction in Patent Machine Translation

Ba-construction is a special structure in Chinese, it has a high utilization rate in patent documents and there is no corresponding sentence in English. Therefore, Ba-construction is a critical issue in machine translation. In this paper, based on the Hierarchical Network of Concept theory (HNC theory), we have an analysis of the Ba-construction in action sentence (XJ) and transfer sentence (TJ), and then conclude 4 main verbs translation formats from the semantic point of view according to corpus. The research results have been applied to our machine translation system and it has improved the correct rate of translation effectively.
