Automatic Evaluation of Output Quality for Speech Translation Systems
Wei Cheng · Zhongwen xinxi xuebao · 2002
The automatic evaluation of output quality for machine translation systems is a difficult problem.Most research in this section is for writing language,which is quit different from oral language.Therefore,this paper provides a new automatic evaluation algorithm for speech translation system.It defines the block according to the word position,tags the information weight and designs several matching methods.All these make the automatic evaluation results more closely to the score of human.And the automatic evaluating can also process more different sentences.Several examinations are given at the end of the paper.They show the algorithm has a good sensitivity for different output quality and its evaluation results is as same as the human's feeling.
