A Web-based English Proofing System for English as a Second Language Users.
Yi Xing, Jianfeng Gao, William B. Dolan · 2008
We describe an algorithm that relies on web frequency counts to identify and correct writing errors made by non-native writers of English. Evaluation of the system on a realworld ESL corpus showed very promising performance on the very difficult problem of critiquing English determiner use: 62 % precision and 41 % recall, with a false flag rate of only 2 % (compared to a random-guessing baseline of 5 % precision, 7 % recall, and more than 80 % false flag rate). Performance on collocation errors was less good, suggesting that a web-based approach should be combined with local linguistic resources to achieve both effectiveness and efficiency. 1
