In Japan, the share of corresponding/leading authors in AI scientific publications is projected to slightly decline from 94.78% in 2024 to 94.41% by 2028. This trend suggests a gradual decrease, albeit very marginal, with a compound annual growth rate (CAGR) indicating a small downward trend over the forecasted five-year period. Although small, this consistent decrease over the years may point to shifting collaborative dynamics or publishing practices within the AI research community.

Future trends to watch for include:

Potential increase in international collaborations influencing leading author shares.
Evolving author contribution models in AI research.
Adaptive publishing standards impacting authorship roles and recognition.
