Fig. 2: Research groups of 383 empirical articles on AI and sustainable development positioned along the two axes of a detrended correspondence analysis with the most explanatory power.
From: Artificial intelligence in sustainable development research
Group 1, health care (red, 49 articles); group 2, vegetation (green, 62 articles); group 3, forecasting (brown, 52 articles); group 4, water (blue, 53 articles); group 5, remote sensing (olive green, 47 articles); group 6, clean energy (pink, 42 articles); group 7, industry (violet, 39 articles); group 8, education (turquoise, 39 articles). For the same word analysis but applied to conceptual/review articles, see Supplementary Fig. 9. To avoid artefacts in the cluster analysis due to extreme article length, we excluded ten articles (Supplementary Figs. 11 and 12). Group titles are based on the most abundant words per group, followed by the number of articles in each group. Group ellipses are based on eigenvalues. Each group is represented by the five most abundant words. Axis titles are the pattern interpretation of the authors. See Table 1 for a short description and Supplementary Table 7 for a full description of the groups.
