基于语料库的地质英语词汇特征分析

Study on Corpus-Based Lexical Features of Geoscientific English

本文以词汇学、语料库语言学、学术英语语言学为理论基础,首先构建一个十三万词次的微型地质英语语料库(Geoscientific English Mini-Corpus, GSEC)。基于此,借助AntConc和Wordsmith等分析软件,以英国学术书面英语语料库(British Academic Written English, BAWE)作为参照语料库,通过对比分析两个语料库,探究了地质词汇的词长、词汇密度、词频,并进而生成词频表,分析语料库中功能词、实义词的特点及构词特征。与此同时,生成GSEC主题词表,分析其中的显著高频词的搭配特点。最后结合地质英语词汇特征,对地质英语教学和地学研究提出了几点建议。

Based on lexicology, corpus linguistics, and English for academic purposes (EAP) linguistics, this paper built a corpus of 130 thousand word tokens called Geoscientific English Mini-Corpus (GSEC, for short). Based on this corpus, using AntConc and Wordsmith software, and taking British Academic Written English (BAWE, for short) as a reference Corpus, this paper analyzed the lexical length, density and frequency of geoscientific English, and then generated frequency list to analyze the features of function words and content words in GSEC and their word-formation characteristics. Furthermore, the GSEC keyword list was generated to analyze the collocation characteristics of the significant high-frequency words. Finally, referring to the features of geoscientific English words, this paper gave out some suggestions on geoscientific English vocabulary teaching and the study on geoscientific field.
