Fig. 6: Comprehensive cluster distribution across river segments midstream allusion-centric semantic clustering network.

a Represents the semantic network diagram of Midstream Cluster 1; b represents the semantic network diagram of landscape monosyllables and words associated with the allusion “Yan Guang & Liu Xiu” (the allusion with the highest recognition degree, i.e., maximum average weighted degree of nodes) in Midstream Cluster 1; c represents the semantic network diagram of Midstream Cluster 2; d represents the semantic network diagram of landscape monosyllables and words associated with the allusion “Tong Jun” (the allusion with the highest recognition degree, i.e., maximum average weighted degree of nodes) in Midstream Cluster 2; e represents the semantic network diagram of Midstream Cluster 3; f represents the semantic network diagram of landscape monosyllables and words associated with the allusion “Fang Gan” (the allusion with the highest recognition degree, i.e., maximum average weighted degree of nodes) in Midstream Cluster 3. In Figures a, c, and e: orange text represents Representative Allusions; green text denotes Natural Landscape Monosyllabic Characters; and blue text stands for Cultural Landscape Monosyllabic Characters. In Figures b, d, and f: orange text represents Representative Allusions; dark green text denotes Natural Landscape Monosyllabic Characters; dark blue text stands for Cultural Landscape Monosyllabic Characters; light green text indicates Natural Landscape Polysyllabic Compounds; and light blue text represents Cultural Landscape Polysyllabic Compounds (Drawn by the author).
