Character-familization and the Extraction of Unlisted Words

字族是围绕一个核心字组成的所有字组的集合,字组之间具有平行关系。字族化是现代汉语词汇的重要生成途径之一,对汉语的编码机制产生了很大影响。文章探讨了字族的特点及字族化的影响,并在平行规则的基础上提出了新词(未登录词)的自动预测和提取方法。

A character-family is a family consisting of all the character combinations which have one same character and are parallel one another. For example, ＂X 热＂ （旅游热、化妆热、考研热……）. As one of the productive ways to the formation of new words in modem Chinese, Character-familization affects the coding mechanism of Chinese deeply. This paper has made an analysis of the characteristics, and effect of the character-family, and further more provide some method to predict and extract new words （unlisted words） automatically on the base of parallel rules.
