Analysis of translation errors and evaluation of pre-editing rules for the translation of English news texts into Spanish with Lucy LT

Abstract

In this paper we study the effect of pre-editing rules on the quality of the translations produced by the MT system Lucy LT when translating English news texts into Spanish. We carried out an error annotation of the first 200 segments of the News Crawl: articles from 2014 corpus and devised a set of 8 pre-editing rules. The application of these rules to a different set of segments from the same corpus results in a reduction of the word error rate of about 11%.
