Study on the comprehensive evaluation method of machine translation quality

Abstract

The accurate evaluation of machine translation quality is the main basis of machine translation systems research and development. Based on the analysis of three translation quality assessment factors, i.e. vocabulary, grammar and discourse, this paper built twelve indicators, which classified into five levels of evaluation index system. Meanwhile questionnaire was designed as well. The people with different age, gender, occupation and cultural level were selected as respondents. Then, the data for machine translation evaluation was obtained from questionnaire. The analytic hierarchy process was applied to determine the weighted vector of machine translation evaluation factors. In addition, on this basis, fuzzy mathematics theory was used to establish the comprehensive evaluation vector of machine translation quality. As a result, the quantity comprehensive evaluation for the translation text quality was realized.
