Question 7 of 33

8. Which of the following statements about participles is incorrect?

Rule-based word segmentation is simple and efficient, but dictionary maintenance is difficult.

The purpose of statistical segmentation is to perform probability calculation on the segmentation results and obtain the segmentation method with the highest probability.

Chinese is different from English natural word segmentation. Chinese word segmentation is a basic step in text processing. The performance of word segmentation directly affects the performance of other modules such as part of speech and syntax tree.

In actual engineering applications, word segmentation generally only uses one method.
