Data Sources and Citation Metrics
The 5th edition of the Research.com Best Business and Management Scientists in Singapore Ranking is primarily based on comprehensive bibliometric data derived from leading open-source databases, including OpenAlex and CrossRef, complemented by multiple other reputable data sources. The citation-based metrics used for the ranking were collected on January 12, 2026, ensuring up-to-date and thorough coverage of scientific output. A researcher’s position in this ranking is determined by their D-index (Discipline H-index), which specifically considers only those publications and citation metrics that pertain to the examined discipline—in this case, Business and Management—thereby providing a precise reflection of expertise and impact within the relevant field.
Scope of Research and Qualification Criteria
The ranking is rooted in a rigorous evaluation of a broad spectrum of scientific profiles. A total of 279,971 scientist profiles spanning all disciplines were initially examined from a variety of bibliometric data sources. Among these, 22 profiles specifically identified within the Business and Management discipline met the initial screening criteria. To qualify for the ranking, a scientist’s D-index had to be at least 30, and a majority of their tier publications needed to be in the area of Business and Management. Additionally, their awards and achievements in the discipline were taken into account to further confirm their prominence in the field.
The D-index threshold is adaptively set in increments of 10 according to the estimated total number of scholars within each discipline, ensuring the consistent inclusion of the top 1% of leading scholars in the ranking. Furthermore, a proximity threshold of 30% or less between a scientist’s general H-index and their D-index was imposed to emphasize a strong disciplinary focus and reduce distortions from cross-disciplinary impact.
Verification Practices and Methodological Rigor
The Research.com team recognizes that raw bibliometric data, while highly informative, cannot serve as an absolute or isolated measure to evaluate scientific output comprehensively. Consequently, all scientist profiles were subjected to manual verification processes and were cross-correlated against publications registered in a broad range of trustworthy sources. This multi-layered verification underpins the robustness and reliability of the ranking.
Although not directly factored into the ranking position, the quantity of papers published in prominent journals and conference proceedings is considered a valuable secondary signal of a researcher’s contribution to their specific area of science. The principal metric driving the ranking—each researcher's D-index—is established using data sourced primarily from OpenAlex and CrossRef, which remain the most prominent and well-established bibliometric databases accessible to the global research community.
