Translation evaluation using optimum template pattern determination method

摘要

To allow the precision of correction to be increased in such an application as correcting an input sentence by using a template pattern for model sentence. A plurality of template patterns for the model sentence are provided. Each of the template patterns is regarded as a plurality of templates of words/phrases by using knowledge of experts and scores are assigned to the words according to their importance. The scores are read (S1, S2), and subsequently the input sentence is read and analyzed (S3, S4). Then, the input sentence is compared with each of the template patterns and the total of scores of matching words is calculated (S5, S6). A template pattern having the highest total score is selected as an optimum template pattern and the input sentence is corrected using the optimum template pattern (S7 to S9). This method increases the likelihood that a template pattern containing a larger number of important words is selected as the optimum template pattern. As a result, the precision of the correction and evaluation can be improved.
