Data Sources and Citation Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Liberia Ranking is based on robust bibliometric data collected from multiple comprehensive and authoritative sources. Primarily, the data sources include OpenAlex and CrossRef, two of the most prominent databases for scholarly publications and citations, complemented by additional bibliometric repositories to ensure breadth and accuracy. The citation-based metrics utilized in the ranking were compiled on January 12, 2026, providing a current and precise snapshot of each scientist’s academic impact within their respective fields.
A researcher’s position in this ranking is determined by their D-index (Discipline H-index), which specifically measures the impact of their publications and citations within the designated discipline of Engineering and Technology. Unlike general citation metrics, the D-index focuses exclusively on discipline-relevant outputs, thereby offering a tailored and meaningful evaluation of expertise and influence in the examined area.
Scope of Research and Qualification Criteria
The ranking assesses a total of 279,971 scientist profiles drawn from an array of bibliometric sources covering all academic disciplines. Among these, 1 scientist specializing in Engineering and Technology in Liberia was identified for consideration. To qualify for inclusion, a scientist must have a D-index of at least 30, with the majority of their tier publications falling squarely within the Engineering and Technology domain. Additionally, awards and notable achievements within the field were taken into account to complement the bibliometric assessment.
The threshold for the D-index is set as incremental steps of 10 based on the estimated population size of scholars within each discipline, while ensuring that the top 1% of leading experts are incorporated into the list. To maintain rigor, the difference between a scientist’s general H-index and their D-index must not exceed 30%, ensuring that overall scholarly impact corresponds well with discipline-specific excellence.
Verification Practices and Methodology Transparency
The Research.com team acknowledges that bibliometric data alone cannot serve as an absolute indicator of a scholar’s contributions. To address this, every scientist profile was subjected to manual verification and cross-checked against publications indexed in a broad spectrum of trustworthy sources. This thorough vetting process ensures the integrity and credibility of the ranking.
While not a factor directly affecting ranking positions, the volume of published papers in reputed journals and refereed conference proceedings was reviewed as an important secondary indicator of a researcher’s prominence and influence within Engineering and Technology. The ranking itself is firmly grounded on the D-index, derived from comprehensive data aggregated from OpenAlex and CrossRef — repositories widely respected and utilized by the global research community.
