Data Sources and Citation-Based Metrics in the 2024 Research.com Best Chemistry Universities in Israel Ranking
The 4th edition of the Research.com Best Chemistry Universities in Israel Ranking is grounded in a rigorous bibliometric analysis, leveraging data from OpenAlex and CrossRef as its primary sources, supplemented by a range of additional reputable data providers. These comprehensive sources provide an extensive foundation of bibliometric information that underpins the development of citation-based metrics for each institution and scholar. All bibliometric data essential to devising the ranking were collected on November 27th, 2024.
The ranking methodology centers on the aggregation of the D-index (Discipline H-index) for all ranking scholars affiliated with each institution whose principal publication area is Chemistry. The D-index reflects exclusively the publications and citation impact within an examined discipline, ensuring that each institution’s position accurately represents the strength and influence of its Chemistry research community.
Scope of Research and Inclusion Criteria
The ranking is built upon a robust review of 279,971 scientist profiles identified from assorted bibliometric sources, with an in-depth analysis conducted for 279,971 scholars specifically in the field of Chemistry. To qualify, each scientist must possess a D-index (Discipline H-index) of at least 40, and the majority of their major publications must fall within the domain of Chemistry. Scientists' awards and notable achievements in Chemistry were also factored into their evaluation.
Recognizing the variations in discipline sizes, the qualifying D-index threshold for top researchers is incrementally raised by 10 points based on the total number of scholars in each discipline, while ensuring the inclusion of the uppermost 1% of leading scholars. To maintain the specificity of field expertise, a proximity criterion requires no greater than a 30% difference between a scientist’s general H-index and their D-index in Chemistry. Additionally, professional distinctions and awards in the field serve as influential secondary factors that contribute to scientist qualification.
Additional Verification and Robustness of the Ranking
The Research.com team acknowledges that raw quantitative data alone cannot provide an absolute measurement of scientific merit. To that end, every scientist profile underwent a rigorous manual verification process and was cross-referenced against publications from numerous trusted sources. While the number of articles published in top-tier journals and conference proceedings does not directly affect a researcher’s rank within Research.com, it remains an important indicator of scholarly contribution and influence within the scientific community.
The institutional positions in the ranking are established by aggregating H-index values for relevant scholars, with data meticulously sourced from OpenAlex and CrossRef—the most authoritative and widely cited bibliometric databases in academia. We invite readers seeking a deeper understanding of our evaluation criteria and ethical standards to review the full methodology on our methodology page.
