“…Information entropy may also be used as a centrality metric to rank nodes (or edges) by importance. In this sense, several authors [ 14 , 17 , 19 , 20 , 21 , 23 , 29 , 30 , 32 , 33 , 36 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ] developed a number of node entropy metrics and provided the appropriate interpretation. Like for graph entropy metrics, many of these are constructed equivalently to the use of information functionals (see Equation ( 9 )) [ 20 , 21 , 44 , 48 , 51 , 56 , 59 , 60 , 61 , 62 ].…”
