Development of an English parser with its validation based on school grammar for material evaluation

本计画发展一个英文文法分析器，并以学校文法为基础进行验证，以供教材自动评量之用。首先，我从科学语法的角度调查了学校语法中的项目，并表明它们与科学语法的各种特征有规律地相关。第二，在调查结果的基础上，我指定了学校语法项目的检测规则，并估计了这些规则的准确性。最后，本项目按照他们的规则开发了英语语法分析器。该系统的原型将作为网络应用程序在互联网上发布。

This project developed an English parser with its validation based on school grammar for automatic evaluation of educational materials. First, I investigated items in school grammar from the view point of scientific grammar and showed that they were regularly correlated with various features in scientific grammar. Second, on the basis of the results of this investigation, I specified detection rules for items in school grammar and estimated the accuracies of these rules. Finally, the project developed the English parser by their rules. A prototype of this system will be released on the Internet as a Web application.
