二语习得与语料库研究的计量分析

Quantitative Citespace-based Analysis of Corpus-based SLA Studies

二语习得研究本质上是跨学科性非常强的独立研究领域,它与语料库语言学、特别是学习者语料库研究有着密切的关系。基于Citespace的计量分析能够以知识图谱的方式呈现并分析语料库与二语习得研究之间的关系、热点以及研究前沿。计量分析发现,基于学习者语料库的词汇习得和程式化语言是一直以来的研究热点。二语学术写作、认知构式与学习者口语研究是近三年来的研究前沿。此外,语料库的数据特性与分析技术在二语习得心理实验研究中得以突显,可能会成为未来的研究趋势。

Second language acquisition research has a close relationship with corpus linguistics or corpora, especially the learner corpora. This paper attempts to analyze this kind of relationship, and focus on the current hot topics and the cutting-edge based on the recent 10-year research literatures. The quantitative tool used in this study is Citespace, by which the data can be automatically reorganized and presented in visual forms. It is found that researches on second language academic writing, cognitive constructions and learners＇ spoken language are the frontier in recent three years. In addition, the role of corpus as experimental data in psychological experiments of second language acquisition research comes to its salience, and might become a research trend in the future.
