Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Engineering and Technology Scientists in Algeria Ranking was developed using bibliometric data primarily sourced from OpenAlex and CrossRef, complemented by multiple other reputable data repositories. These sources collectively provide a comprehensive and up-to-date overview of scientific publications and citations. The bibliometric data utilized to devise the citation-based metrics for the ranking were collected on January 12, 2026, ensuring the use of the most current information available at the time of compilation.
A scientist’s position in the ranking is determined by their D-index (Discipline H-index), which is a variant of the traditional H-index calculated exclusively with respect to papers and citation metrics within the examined discipline. This approach ensures the ranking reflects a researcher’s impact and contributions specifically in the field of Engineering and Technology, rather than their overall scholarly output.
Scope of Research and Inclusion Criteria
The ranking process examined a total of 279,971 scientist profiles identified from a broad spectrum of bibliometric data sources spanning all scientific disciplines. Within this dataset, 8 scientists specialized in the field of Engineering and Technology were specifically analyzed to create this focused ranking.
- To qualify for inclusion, a scientist’s D-index had to be at least 30.
- A majority of their tier publications needed to be in the area of Engineering and Technology to ensure disciplinary relevance.
- Consideration was also given to scientists’ awards and achievements within the Engineering and Technology domain to further validate impact in the field.
The threshold for the D-index to select top researchers is calibrated in increments of 10 relative to the estimated number of scholars in each discipline. This method guarantees the inclusion of the top 1% of leading scholars within the ranking. Additionally, a proximity threshold of 30% or less between a scientist’s general H-index and their D-index was maintained to confirm focused disciplinary excellence rather than broad, scattered citations.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone are insufficient to fully capture scholarly impact, the Research.com team performed meticulous manual verification of all scientist profiles featured in the ranking. This process involved cross-correlating the profiles against publications indexed in a wide array of trustworthy sources to ensure accuracy and reduce errors.
While not directly influencing the position within the ranking, the number of papers published by a scientist in prominent journals and conference proceedings was considered a valuable secondary indicator of their contribution to the Engineering and Technology field.
The ranking positions derive from each researcher's D-index as calculated from data obtained through OpenAlex and CrossRef, which stand as the most prominent and well-recognized bibliometric databases accessible to the research community.
