PECAT: a computer-aided translation tool based on bilingual corpora

With the widespread use of computers in translation work and daily life, there are more and more bilingual corpora becoming available. In this paper, the PECAT (Pilot English-Chinese Computer-Aided Translation) system, based on bilingual corpora, is described. There are mainly three modules in our system: a corpus-processing module, a sentence-matching module and a post-editing module. In order to increase the coverage of input source sentences, the text alignment in the corpus-processing module is based on the chunk level. The matching algorithm of input sentences and source sentences is a three-layer edit-distance algorithm guided by the user, which includes information about word morphology and part-of-speech (POS). Preliminary experiments show promising results
