Automatic detection and analysis method for English composition grammar errors

Abstract

The invention provides an automatic detection and analysis method for English composition grammar errors. According to the method, first, sentence segmentation is performed on an input English composition to be detected; next, word segmentation is performed on words in each sentence after sentence segmentation; then, spelling checking is performed on the words; after it is detected that all spellings are correct, part-of-speech tagging is performed on all the words; tagging results of the multi-tag words after tagging are corrected; the flow chart of different error instance rules is constructed; combined with the existing grammar rules and error examples, the grammar check is performed comprehensively on the sentences; finally the position where the grammatical error occurs in the composition is located, and the specific modification opinion is given. The method can locate the grammatical error position and give specific error content and solution; at the same time, the grammar rulescan be extended by modifying the error example flow chart. The method has high grammar error detection and correction capability, which can quickly detect and give a feedback of an English composition, and can be applied to a real-time environment.
