| Summary: | 碩士 === 國立交通大學 === 多媒體工程研究所 === 99 === Nowadays, elementary students start to learn English, taking English test becomes more and more popular, and The European Union proposed to make English, French and German as the official language of the “Common Patent Policy” of the EU patent. It is a trend for people to learn English due to the above reasons. Listening, Speaking, Reading ad Writing are the four basic skills in learning a language. But it is not easy for people to learn how to write. After wring a passage or a composition, the only way to check its correctness is to check it manually by a teacher. Checking a composition is time-consuming. And since there is no standard answer to the composition, the grading standard way vary. Even though some system can find the grammar errors in passages, their correctness still need improvement.
Therefore, we try to implement a grammar checker with low error rate and high error checking rate. We first take the basic grammar rules as the base to design several modules with different functions. Then we continue adding other rules to those modules according to the error classification of CLEC. Finally we examine our modules with passages in CLEC. By using the corresponding approaches, spelling errors and grammar errors can be marked and served as references for the graders.
Also, for Chinese people, since English is not out mother tongue, we will make some errors that native speakers would not. And these errors may not be found out by those grammar checkers which were implemented by native speaker. Therefore, we hope to implement an English grammar checker which was specially designed for Chinese.
