A Fuzzy VOSviewer Modelling of EMI Research: A Multifaceted Perspective

English plays an increasingly important role in non-English-speaking countries, and bilingual elites with English-Chinese always make a country's economy prosperous.  Thus, to efficiently promote and implement the “English as a Medium Instruction” (EMI) program in higher education to raise university students’ English proficiency is inevitable. This study collects a total amount of ۵۹۴ EMI important papers of articles, periodicals, books, etc., of the last ۲۰ years from the Scopus database and sequentially conducts a bibliometric literature analysis of these papers with the VOSviewer software tool to gain the study conclusions. In network visualization analysis, especially when using tools like VOSviewer, fuzzy sets are essential for capturing the multifaceted nature of node relationships, enabling a more precise and informative representation of network structures and connections. According to the analysis results, the EMI study mainly started in ۲۰۱۴, and EMI papers have increased since. Four EMI majors have been focused. They are the aspects of higher education, the issues of trans-language, the perspectives of teachers and students, and the viewpoints of human social behavior. This research simultaneously arranges and provides valuable information on the journals, authors, units, institutes, and countries that have published EMI articles the most
