Table 5 Exemplary calculation of average normalized co-occurrence (ANCO) considering three artificial municipalities and two artificial categories

From: A new approach to semantic sustainability assessment: text mining via network analysis revealing transition patterns in German municipal climate action plans

  Municipality 1 Municipality 2 Municipality 3
Total number of measures in MCAP of individual municipality 70 60 100
Number of measures in which two categories cx and cy co-occur 14 9 10
Normalized co-occurrence 14/70 = 0.2 9/60 = 0.15 10/100 = 0.1
Average normalized co-occurrence (ANCO) (0.2 + 0.15 + 0.10)/3 = 0.15
