Data Sources and Citation Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Slovenia Ranking is primarily based on comprehensive bibliometric data obtained from leading databases, including OpenAlex and CrossRef, supplemented by multiple other reputable sources. To ensure accuracy and recency, the bibliometric data used to devise citation-based metrics were collected on January 12, 2026. The ranking methodology centers around a researcher's D-index (Discipline H-index), which reflects scholarly impact within a specific discipline by considering only relevant papers and citation counts within that field.
Scope of Research and Selection Criteria
This ranking is grounded on an extensive examination of 279,971 scientist profiles identified from a diverse array of bibliometric databases across all scientific disciplines. Specifically, for this edition, the focus was on the 4,000 scientists classified under Engineering and Technology.
To qualify for inclusion, a scientist had to meet the following criteria:
- A D-index of at least 30.
- A majority of their tier publications must be in the area of Engineering and Technology.
- Recognition of awards and achievements pertinent to Engineering and Technology was also factored into evaluation.
The threshold for the D-index is set as increments of 10 relative to the estimated total number of scholars within each discipline. This approach ensures that the ranking consistently includes the top 1% of leading scholars by discipline. Additionally, a proximity criterion requires that there is no greater than a 30% difference between a scientist's general H-index and their D-index. This maintains alignment between overall and discipline-specific impact.
Verification and Validation Processes
We acknowledge that raw bibliometric data alone cannot serve as a definitive measure of scholarly performance. Therefore, every scientist profile included in the ranking underwent manual verification and was cross-checked against publications listed in a broad spectrum of trustworthy and verified sources.
While the position within the ranking is determined exclusively by the D-index based on data from OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric databases—additional factors such as the number of papers published in leading journals and conference proceedings are considered valuable secondary indicators of a scientist’s contribution to their area of expertise.
