英汉海事术语句法型式定量分析

论文摘要

术语是专业知识的载体。它的创建、普及和消亡动态地展现了一个学科的发展、演变历程。专业术语数据库作为一种知识源,为研究人员便捷地获取专业知识提供重要支持。术语提取的构建是自然语言处理领域中的一项重要课题。而术语自动抽取是一项工作量极大的工程,如何快速并准确地抽取术语是一项急需解决的关键问题。本文对中英海事术语的句法型式进行统计分析,旨在1)抽取英汉术语高频句法型式；2)英汉术语句法型式对应概率,为优化现有术语自动提取方法,提高术语自动抽取效率提供知识资源和科学依据。本文以海事术语的句法型式为研究对象,突破名词短语的限制,探讨更多的非名词性结构的专业术语句法型式,主要选取出现频率较高的两词、三词术语作为数据来源,通过对术语进行词性附码,确定英语术语的句法型式特征,再分析与之相对应的汉语术语的句法型式。然后以翻译对等理论为依据,同时结合词汇间粘合度以及术语内部词语的搭配特征,分析出具有相同语法型式的英汉双语术语的对等程度,统计出具有同类句法型式术语的对等概率。研究结果表明,英语两词术语覆盖率80%以上的句法型式为：名词+名词,形容词+名词,动名词+名词以及动词过去分词+名词；与之相对应的覆盖率70%汉语术语句法型式为：名词+名词,名词,动词+名词,形容词+名词,名词+动词,名词+名词+名词。英语三词术语覆盖率70%以上的句法型式为：形容词+名词+名词,名词+名词+名词,名词+连词+名词,形容词+形容词+名词,名词+动名词+名词,名词+形容词+名词,专有名词+专有名词+专有名词,动词过去分词+名词+名词,动名词+名词+名词；与之相对应的覆盖率近70%的汉语术语句法结构为：名词+名词,名词+名词+名词,名词,动词+名词,名词+动词+名词,形容词+名词,形容词+名词+名词,动词+名词+名词,名词+动词,名词+名词+动词。
