Summary

A peer-reviewed critique in Geoenergy reveals that African-led geoscience AI/ML research capacity is significantly undercounted in studies linked to the Deep-time Digital Earth (DDE) initiative. While a DDE-linked paper identified only 8 African-led publications in 2024, a comparable bibliometric analysis found over 150 publications across 22 African countries during the same period. This discrepancy highlights how methodological choices in bibliometrics, particularly baseline construction, can drastically alter the representation of research landscapes. The original DDE-linked research lacked transparency regarding its methods, limitations, funding, and competing interests. Such undercounting can lead to policy decisions that favor external provision over leveraging existing, growing African AI/ML centers, underscoring the critical need for explicit communication of analytical assumptions and indexing choices.

Key takeaway

For AI Scientists evaluating global research landscapes or proposing collaborative initiatives, you should critically examine the methodological transparency and baseline construction of bibliometric studies. An undercount of local capacity, as seen with African geoscience AI/ML, can misdirect funding and policy towards external solutions rather than fostering existing, distributed research bases. Ensure your analyses explicitly communicate all assumptions and limitations to prevent misinterpretation and support equitable partnerships.

Key insights

Bibliometric methodologies significantly influence perceived research capacity, shaping policy and funding decisions.

Principles

• Baseline construction in bibliometrics is not neutral.
• Transparency in methods is crucial for accurate representation.

Method

A comparative bibliometric analysis was performed by screening publication titles and abstracts to identify African-led geoscience AI/ML research, contrasting with an existing DDE-linked study.

In practice

• Scrutinize bibliometric baselines for methodological transparency.
• Consider diverse indexing and filtering choices in research counts.

Topics

• Deep-time Digital Earth
• African Geoscience AI/ML
• Bibliometric Analysis
• Research Capacity Undercounting
• Publication Bias
