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.

Description

technical field [0001] The invention generally relates to the field of natural language processing research, in particular to an automatic detection and analysis method for grammatical errors in English compositions. Background technique [0002] Today is a highly globalized world. In this context, English has become an indispensable bridge to communicate with the world. English is the most widely used language in the world. There are about 400 million people who speak English as their mother tongue, but more than 1 billion people communicate with English as a second language. Non-native English learners write up to 70% of English texts, and they will inevitably make grammatical mistakes in the process of writing English. Especially in academic communication, English papers, as an important tool to demonstrate personal academic level, play an important role in the process of academic communication. The automatic detection method of English composition grammar can help vari...
