Inclusion in the Scopus database is not a permanent status for academic journals. To maintain the quality, credibility, and integrity of its indexed content, Scopus continuously evaluates journals after they have been accepted for coverage. One of the key mechanisms supporting this ongoing evaluation process is the RADAR system, which serves as an early-warning and monitoring framework designed to identify journals that may no longer meet Scopus quality standards.
The RADAR system analyzes a variety of quantitative and qualitative indicators associated with journal performance. These indicators may include citation patterns, publication behavior, editorial practices, content quality, and other bibliometric measures. By continuously monitoring these factors, the system can detect unusual trends or potential concerns that warrant further investigation. For example, excessive self-citation, citation stacking, abrupt changes in publication volume, declining citation impact, or irregular publishing practices may trigger alerts within the monitoring process.
Importantly, the RADAR system does not automatically remove journals from Scopus. Instead, it functions as a screening mechanism that helps identify journals requiring closer examination. When a journal is flagged, the case may be reviewed by the Scopus Content Selection and Advisory Board (CSAB), an independent group of subject experts responsible for evaluating journal quality and adherence to Scopus standards. The board examines the available evidence and determines whether corrective actions, continued monitoring, or discontinuation of coverage is appropriate.
The existence of the RADAR system reflects Scopus's commitment to safeguarding research quality and protecting the scholarly community from questionable publishing practices. As academic publishing continues to expand globally, maintaining consistent standards across thousands of journals becomes increasingly important. Continuous monitoring helps ensure that journals remain committed to rigorous peer review, ethical publishing conduct, editorial transparency, and meaningful scholarly contribution.
For researchers, understanding the role of the RADAR system is essential when selecting publication outlets. A journal's inclusion in Scopus indicates that it has met established quality criteria, but researchers should also recognize that indexed journals remain subject to ongoing evaluation. Choosing journals with strong editorial governance, ethical publishing practices, and sustained academic impact can help ensure that research is disseminated through reputable and internationally recognized channels. Ultimately, the RADAR system contributes to preserving the reliability and prestige of the Scopus database while promoting excellence in scholarly communication worldwide.
