Qiaoming Zhu · Zhongwen xinxi xuebao · 2011
Context dependent word errors in English texts are errors in which one is incorrectly substituted by another word without spelling mistake.This paper mainly discusses how to detect this type of errors.We prospose to extract the context festers by a method that firstly extract features of syntax and semantics from the word context,and then select the festures by the Document Frequency and the Information Gain to do feature selection..Further,we model the detecting task as a classification using the Winnow algorithm.With five-across validation among 61groups of confusion sets,the average precision and recall are 96%,79.47%,respectively.
