- Undirected Graph:
-
An undirected graph is a graph, i.e., a set of objects (called vertices or nodes) that are connected together, where all the edges are bidirectional
- Page Rank:
-
It computes stationary distribution of chain of resources from web graph
- Link Rank:
-
Importance of links in a random surfer model
- In-degree and Out-degree:
-
The number of head endpoints adjacent to a node is called the in-degree of the node and the number of tail endpoints adjacent to a node is its out-degree
Definition
The entry discusses the problem of identifying communities in the directed networks. This entry proposes a new approach for better results derived from the link rank definition of the modularity. The new proposed approach has evolved from the concept of statistical surprising by removing one of its observed shortcomings. The inverse link rank method's performance is then discussed when applied to real-world data. The proposed...
