Correcting Serial Grammatical Errors based on N-grams and Syntax
作者 Jian-cheng (Jian-cheng)Jim Chang (Jim Chang)Jason S. Chang (Jason S. Chang)
中文摘要
In this paper, we present a new method based on machine translation for correcting serial grammatical errors in a given sentence in learners’ writing. In our approach, translation models are generated to translate the input into a grammatical sentence. The method involves automatically learning two translation models that are based on Web-scale n-grams. The first model translates trigrams containing serial preposition-verb errors into correct ones. The second model is a back-off model, used in the case where the trigram is not found in the training data. At run-time, the phrases in the input are matched and translated, and ranking is performed on all possible translations to produce a corrected sentence as output. Evaluation on a set of sentences in a learner corpus shows that the method corrects serial errors reasonably well. Our methodology exploits the state-of-the art in machine translation, resulting in an effective system that can deal with many error types at the same time.
