对外汉语教材等级词类频统计模块构建 ─ 一种辅助对外汉语教材词汇难评量的工具

Construction of an Approach for Counting Chinese Graded Words and Characters ─ A Tool for Assessing Difficulty Level of Word in Chinese Language Teaching Materials Writing System

在对外汉语教材的编着过程中，用词频度和难度直接影响教材编着的质量，根据《汉语水平词汇与汉字等级大纲》（以下简称《大纲》）8000多等级用词目、词性、难度等级三个属性，设计并实现对外汉语教材编着系统难度等级词频统计模块，并在20万教材语料基础上，进行实验。实验证明，在速度上取得了较为良好的效果。

In the process of writing teaching material of teaching Chinese as a foreign language， Graded Words and Characters directly influence quality of the teaching material. In this paper， on the basis of Graded Words and Characters for Chinese Proficiency， we design Statistics modules for obtaining various frequencies of words in teaching material and showing the distributions of them. We do an experiment with teaching corpus of 200000 characters and get a good performance.
