语言复杂度是认知语言学视阈下二语研究的热点之一。本文运用CiteSpace这一文献分析可视化软件,对国际权威数据库Web of Science-SSCI核心合集中有关语言复杂度的829篇论文进行深度挖掘,绘制出1990至2015年间语言复杂度研究的文献共被引知识图谱、文献共被引聚类知识图谱和关键词共现知识图谱,可视化地呈现了该领域的高影响力文献、核心领域和热点课题,旨在对认知语言学理论指导下的二语习得语言复杂度研究进行元分析。研究发现,认知语言学视阈下的语言复杂度主要被应用于任务复杂度研究中;句法复杂度及语言复杂度和流利度与准确度之间的关系是当前国际语言复杂度研究的热点课题。
Linguistic complexity is one of the hot topics in second language research from the perspective of cognitive linguistics. In this paper, CiteSpace is used to analyze the visualization software to deeply dig 829 essays on linguistic complexity in the core collection of Web of Science-SSCI, an international authoritative database, and draw the literature of linguistic complexity research from 1990 to 2015 At the same time, the maps and documents have been clumped together and the key word co-occurrence knowledge map has been visually presented in the field of high impact literature, the core areas and hot topics, designed to cognitive linguistics theory under the guidance of second language Have to do the language analysis of the complexity of the meta-analysis. The study found that the linguistic complexity under the linguistic threshold of cognitive linguistics is mainly used in the study of task complexity; the relationship between syntactic complexity, language complexity, fluentness and accuracy is the hotspot of the study of international language complexity Question.
