摘    要:本文介绍的工作是在汉语句法分析研究基础上的一种应用研究,对术语如何下定义问题进行了理论上的探讨。术语的定义形式在汉语语法结构方面提供了模板结构和构成方式,可以作为知识发现研究的数据基础,也可以作为特定领域的语法知识系统。本文针对电子学和计算机领域的语料进行了分词和词性标注处理,然后应用句法分析工具分析出句子中的短语成分,并根据汉语句子的句型结构,总结出术语定义的结构特点,自动提取定义的模板。最后根据已建立的数据和概念描述,给出了术语发现的算法。

关 键 词:计算机应用  中文信息处理  句法分析  知识发现  术语定义

Abstract:The work presented in this paper is a kind of application based on Chinese syntactic parsing. It is theoretic discussion to define term names. The definition of terms provides patterns and structures for term concepts and is the data basis of knowledge discovery. The structures of term definitions also can be a grammar knowledge system in special domain. In this paper, the corpora of electronics and computer domain are firstly segmented and tagged with part of speech. Then two parsers are applied to obtain structures and phrases of sentences. According to the syntactic structures of Chinese sentences, we have summarized the structure characteristics of term definitions and automatically extracted the patterns of definitions. Finally, we describe the algorithm to define a new term according to the built data knowledge.
Keywords:computer application  Chinese information processing  syntactic parsing  knowledge discovery  term definition
