A Bibliometric Analysis of Linguistic Variables Based on Intuitionistic Fuzzy Set

The intuitionistic fuzzy set (IFS) has been extensively investigated, particularly concerning linguistic variables. Therefore, several modifications of linguistic variables based on IFS have been proposed in the literature. This study aims to explore scientific data related to linguistic variables based on IFS through bibliometric analysis. Data were obtained from the Scopus database and analyzed using VOSviewer software to evaluate the structure, conceptual evolution, and trends. The Scopus database provided 329 documents spanning the years 2002–2024. Specifically, the study examines the distribution of published documents per year, the most frequent keywords, the most influential authors, and the most frequently referenced sources. By highlighting significant articles and outlining publication topics, this analysis helps to enhance the quality of reviews in this field. This bibliometric analysis provides valuable insights for researchers and practitioners interested in utilizing linguistic variables based on IFS, offering an overview of current research trends and suggesting potential directions for further study.
