The Integrated Evaluation Method of Machine Translation Quality Based on Z-numbers

The evaluation of machine translations is of great significance to machine translation research. The evaluations are based on the judgments of the evaluators, and it is necessary for us to ensure that the judgments are reliable. Since the Z-number has the potential to overcome the issue of information reliability, introduction of this concept brings an improvement to describe uncertain information in multicriteria decision making. Inspired by this development, we utilize the Z-number to formulate an integrated translation evaluation method. The concrete steps of the method are given, and two different machine translated target texts that are from the same original text are studied using the method. It is shown that the proposed method provides helpful guidance of machine translation quality evaluation.
