An Automatic Evaluation Method for Localization Oriented Lexicalised EBMT System

To help developing a localization oriented EBMT system, an automatic machine translation evaluation method is implemented which adopts edit distance, cosine correlation and Dice coefficient as criteria. Experiment shows that the evaluation method distinguishes well between “good” translations and “bad” ones. To prove that the method is consistent with human evaluation, 6 MT systems are scored and compared. Theoretical analysis is made to validate the experimental results. Correlation coefficient and significance tests at 0.01 level are made to ensure the reliability of the results. Linear regression equations are calculated to map the automatic scoring results to human scorings.
