Index | Metric Label | Metric Interpretation | Metric Category |
|---|---|---|---|
1 | Average Degree | Number of edges per node | Compactness |
2 | Clustering Coefficient C | Ratio of total number of edges among the neighbours of the node to the total number of edges that can exist among the neighbours of the node per node | Clustering |
3 | Clustering Coefficient D | Ratio of total number of edges among the neighbours of the node and the node itself to the total number of edges that can exist among the neighbours of the node and the node itself per node | Clustering |
4 | Clustering Coefficient E | Ratio of total number of edges among the neighbours of the node to the total number of edges that can exist among the neighbours of the node per node excluding the isolated nodes | Clustering |
5 | Average Eccentricity | Average of node eccentricities where the eccentricity of a node is the maximum shortest path length from the node to any other node in the graph | Compactness |
6 | Diameter | Maximum of node eccentricities | Compactness |
7 | Radius | Minimum of node eccentricities | Compactness |
8 | Average Path Length | Average distance between the nodes of a graph, where the distance between two nodes is the number of edges in the shortest path that connects them | Compactness |
9 | Hop Plot Exponent | Slope of the line fitted to the hop plot values in log-log domain, where the hop plot value for hop h is the number of node pairs for which the path length between the pairs is less than or equal to h | Compactness |
10 | Giant Connected Component Ratio | Ratio between the number of nodes in the largest connected component in the graph and total the number of nodes | Clustering |
11 | Number of Connected Components | Number of clusters in the graph excluding the isolated nodes | Clustering |
12 | Average Connected Component Size | Number of nodes per connected component | Clustering |
13 | Percentage of Isolated Points | Percentage of the isolated nodes in the graph, where an isolated node has a degree of 0 | Compactness |
14 | Percentage of End Points | Percentage of the isolated nodes in the graph, where an isolated node has a degree of 1 | Compactness |
15 | Number of Central Points | Number of nodes within the graph whose eccentricity is equal to the graph radius | Compactness |
16 | Percentage of Central Points | Percentage of the central points in the graph | Compactness |
17 | Average of Edge Lengths | ||
18 | Standard Deviation of Edge Lengths | ||
19 | Skewness of Edge Lengths | Statistics of the edge length distribution in the graph | Spatial Uniformity |
