#### 2.5.2 Accuracy Evaluation of Uyghur Translation  
In evaluating the performance of a rapid translation API in translating Chinese to Uyghur text, we have adopted a quantitative strategy aimed at measuring the consistency between the translation output and the manually corrected Uyghur text, thereby judging the accuracy of the translation. The core of this process lies in calculating the translation accuracy rate, which measures the precision of the translation by comparing the word-level match between the translation result and the reference text--that is, the Uyghur text confirmed as accurate by expert proofreading. The specific process of calculating the accuracy rate comprises five key steps: First, we select a segment of manually corrected Uyghur text as the reference standard. Then, we count the total number of words in this reference text, which serves as the denominator for subsequent calculations. Next, we compare the output of the rapid translation API with the reference text word by word, identifying the words that match exactly between the two, which are considered as correctly translated parts. Based on this, we sum up the number of all correctly translated words, serving as the numerator for calculating the accuracy rate. Finally, we divide the number of correctly translated words by the total number of words in the reference text, multiply by 100%, and thus obtain the percentage value of the translation accuracy rate. Following these steps, we can obtain quantitative analysis results for the translation accuracy rate, which provide us with intuitive feedback on the performance of the rapid translation API in converting Chinese to Uyghur text.Let the number of correctly translated words be denotedas A, and the total number of words in the reference translation be denoted as B, Accuracy Calculation Formula:  
\[Accuracy=\frac{A}{B}\times 100\%\]  
We used the Quick Translate platform to translate them into Uyghur. The corrected Chinese text after manual correction of the originally recognized text was batch translated into Uyghur through the Quick Translate API, resulting in Uyghur translation texts. Further, manual inspection and correction were performed on the translated Uyghur texts. The accuracy was calculated by comparing the translated Uyghur texts with the manually corrected Uyghur texts, as shown in Figure 6. The average accuracy rate for the randomly sampled 50 sentences is 0.9909.  
Using the same approach, we grouped the Uyghur translations of the 102 books into 51 sets of two books each and calculated the average accuracy rate for each set, as depicted in Figure 7. The final overall average accuracy rate for the 51 sets of data was 0.9903. By utilizing the Quick Translate platform to translate the corrected Chinese texts into Uyghur, we significantly reduced the processing time required for translation. Moreover, the remarkably high translation accuracy of Quick Translate improved the efficiency of manual inspection and grammatical correction, effectively ensuring that the translated corpus does not impact the output of subsequent models.
