Interest in Artificial Intelligence (AI) continues to grow rapidly, hence it
is crucial to support researchers and organisations in understanding where AI
research is heading. In this study, we conducted a bibliometric analysis on
257K articles in AI, retrieved from OpenAlex. We identified the main conceptual
themes by performing clustering analysis on the co-occurrence network of
topics. Finally, we observed how such themes evolved over time. The results
highlight the growing academic interest in research themes like deep learning,
machine learning, and internet of things
