Data Sources for the 12th Edition of the Best Computer Science Scientists in Egypt Ranking
The 12th edition of the Research.com Best Computer Science Scientists in Egypt Ranking draws primarily on comprehensive bibliometric data aggregated from OpenAlex and CrossRef, two of the most respected and widely adopted scholarly data platforms. In addition to these primary sources, multiple other bibliometric repositories and data integrations were utilized to ensure robustness and breadth in the coverage of scientific output. The citation-based metrics underpinning the ranking were compiled as of January 12, 2026, ensuring the latest available data was incorporated.
A scientist's position in this ranking is fundamentally determined by their D-index (Discipline H-index). The D-index refines traditional citation metrics by focusing exclusively on publications and citations relevant to the examined discipline—Computer Science in this instance—thereby providing a precise measure of impact within the specific field.
Scope of Research and Eligibility Criteria
The ranking process involved the examination of a total of 279,971 scientist profiles sourced from a broad spectrum of bibliometric databases covering all scientific disciplines. Within this extensive dataset, 12 scientists specializing in Computer Science in Egypt met the criteria to be included in the final ranking.
To qualify for ranking consideration, a scientist’s D-index had to be at least 30, with the majority of their tier publications categorized under Computer Science. Additionally, notable awards and achievements within the field were factored into the evaluation to complement the bibliometric indicators. The threshold for the D-index is dynamically set in increments of 10 relative to the estimated total number of scholars per discipline, explicitly designed to encompass the top 1% of leading researchers in the field.
Another key criterion ensures alignment between a researcher’s general H-index and their D-index; specifically, the proximity between these two indices must not exceed 30%. This safeguard ensures that the ranking prioritizes scholars whose impact is consistently demonstrated within the specified discipline rather than across unrelated fields.
Verification and Validation Practices
The research team behind the ranking recognizes that raw bibliometric data, while valuable, cannot serve as an absolute measure of scholarly output. Accordingly, all scientist profiles were subjected to meticulous manual verification and cross-correlation against a wide range of reputable publication sources to affirm accuracy and completeness.
While the sheer number of papers published in prestigious journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary indicator of a scientist’s substantive contributions to Computer Science research.
The final ranking is established using the rigorously curated D-index values derived from data in OpenAlex and CrossRef, both of which maintain high standards for metadata quality and citation indexing.
