According to CiteSpace5.8. R1, the top ranked
item by citation counts is "critical discourse
analysis" with citation counts of 169. The second
one is "nonjudgmental" with citation counts of 60.
The third is "ideology" with citation counts of 39.
The 4th is "corpus" with citation counts of 13. The
5th is "discourse analysis" with citation counts of
13. The 6th is "cognitive linguistics" with citation
counts of 9. The 7th is "discourse strategy" with
citation counts of 8. The 8th is "systemic functional
linguistics" with citation counts of 8. The 9th is
"news discourse" with citation counts of 7. And the
10th is "positive discourse analysis" with citation
counts of 6.
While the top ranked item by centrality is
"critical discourse analysis" with centrality of 306.
The second one is "nonjudgmental" with centrality
of 111. The third is "ideology" with centrality of 64.
The 4th is "discourse analysis" with centrality of 28.
The 5th is "corpus" with centrality of 21. The 6th is
"The New York Times" with centrality of 20. The
7th is "text analysis" with centrality of 19. The 8th is
"paid interviews" with centrality of 17. The 9th is
"news field" with centrality of 17. And the 10th is
"discourse strategy" with centrality of 16.
We can find that among the 280 critical
discourse analysis-related papers included in CNKI's
core journal full-text database from 2000 to 2020,
"critical discourse analysis" is the largest node, with
a frequency of 169, followed by "nonjudgmental",
"ideology", "corpus", "discourse analysis",
"cognitive linguistics" and "discourse strategy" and
so on. Besides, centrality can determine the research
hotspots in the research field, reflecting the degree
of co-words of keywords. While keywords with high
centrality can reflect the focus and direction of
researchers in a certain period of time, and are likely
to become the hotspots and frontiers of research.
Sorted by centrality, "critical discourse analysis",
"nonjudgmental" and "ideology" are listed in the top
three, followed by "corpus", "New York Times",
"text analysis", "paid interview" and "news". These
words play an important mediating role in the field
of critical discourse analysis research.
4 CONCLUSION
The visual analysis software CiteSpace5.8. R1 is
used to conduct statistical analysis on critical
discourse analysis related research in the full-text
database of CNKI’s core journals from 2000 to
2020. Integrating the relevant knowledge of
literature statistics and the information in the visual
knowledge graph, we can find that since 2008, the
application-related research of critical discourse
analysis has risen sharply, and the number of papers
in 2011 and 2016 has also reached a peak,
respectively 26 and 28 papers. But in terms of the
number of papers published each year, there were
significant fluctuations between 2006 and 2016,
indicating that the number of research papers
published in this area has not been stable.
Nonetheless, the number of papers published has
remained relatively stable since 2016, indicating the
continuous development of CDA research in recent
years.
At the same time, from the perspective of
journals, the four journals "Foreign Language
Studies", "Foreign Languages and Foreign
Language Teaching", "Foreign Languages Journal"
and "Foreign Language Teaching" have roughly
formed the core journal group of critical discourse
analysis research in China. While on the side of the
authors, Tian Hailong, Xin Bin, Liu Ming, Liu
Wenyu, Zhang Hui, Ding Jianxin, Miao Xingwei, Ji
Yuhua, Zhang Tianwei, and Zhu Guisheng all
constitute the core group of authors in this field. In
addition, from the perspective of research hotspots,
critical discourse analysis, nonjudgmental, and
ideology are the three hotspots in the development
of this field.
In general, the development of critical discourse
analysis research has been on the right track,
producing core journal groups, core author groups,
stable research institutions, and gradually forming
research hotspots and directions. However, there are
some limitations in the study of CDA, such as the
lack of interdisciplinary perspective and the lack of
breakthrough in many specific analytical techniques.
While with the rapid development of information
technology, the advent of the era of big data has
brought new development opportunities for critical
discourse analysis research. We believe that based
on big data and the development of mobile internet,
critical discourse analysis will reflect greater value
in Chinese language teaching and related research.
