| Abstract: | The thought and its realization algorithm to get the language knowledge that contained in Chinese text and structure automatic error detection and correction needed knowledge sets are interpreted in this paper. Because of the data sparse problem, the accessing technology of error detection knowledge sets is discussed. According to different error sources, the ways of structuring the similar-code dictionary, the two-direction dictionary driven by Chinese character and the skeleton key dictionary, are presented. The Chinese text automatic error detection and correction system based on this knowledge sets have achieved effect, its recall rate and accuracy rate as well as the validity of suggestion of error correction have got great raising. |
| Keywords: | knowledge getting the knowledge sets of error detection the knowledge sets of error correction corpus automatic error detection and correction system |
