Eigenvector Centrality
Eigenvector Centrality | Network Encyclopedia What is an Eigenvector Centrality? Eigenvector Centrality measures the influence of a node in a network by considering not just the number of its connections, but also the importance of the nodes it is ...
Spring Layout
Spring Layout | Network Encyclopedia What is a Spring Layout? A Spring Layout is a type of network visualization algorithm that uses the principles of physics to position nodes in a way that reveals the structure of the network. Nodes are treated as ...
Clustering
Clustering | Network Encyclopedia What is Clustering? Clustering in network science refers to the tendency of nodes to form tightly connected groups or triangles. A cluster occurs when a node’s neighbors are also connected to one another, creating a ...
Path Length
Path Length | Network Encyclopedia What is Path Length? Path Length refers to the distance, measured in the number of edges, between two nodes in a network. It quantifies how many steps it takes to travel from one node to another. Path length is a ...
Closeness Centrality
Closeness Centrality | Network Encyclopedia What is Closeness Centrality? Closeness Centrality measures how close a node is to all other nodes in the network, based on the shortest paths. A node with high Closeness Centrality has shorter average ...
Betweenness Centrality
Betweenness Centrality | Network Encyclopedia What is Betweenness Centrality? Betweenness Centrality measures how often a node lies on the shortest paths between other nodes in a network. It quantifies the extent to which a node acts as a bridge or ...
Weighted Edges

Bipartite Network
Bipartite Network | Network Encyclopedia What is a Bipartite Network? A Bipartite Network is a specific type of multimodal network in which nodes are divided into two distinct sets, with edges connecting nodes only between the sets. Common examples ...
Multimodal Network
Multimodal Network | Network Encyclopedia What is a Multimodal Network? A Multimodal Network consists of nodes of different types, with edges representing relationships between these distinct node types. For instance, a network might include people, ...
Unimodal Network
Unimodal Network | Network Encyclopedia What is a Unimodal Network? A Unimodal Network is a network where all nodes represent the same type of entity. These networks focus on homogeneous relationships, such as friendships, collaborations, or ...
Directionality
Directionality | Network Encyclopedia What is Directionality? Directionality indicates whether edges in a network have a defined direction. In directed networks, edges have arrows that specify the flow of resources, information, or influence. In ...
Reciprocity
Reciprocity | Network Encyclopedia What is Network Reciprocity? Reciprocity measures the extent to which directed relationships in a network are mutual. A reciprocal relationship exists when two nodes are connected by edges pointing in both ...
Network Layout
Network Layout | Network Encyclopedia What is Network Layout? Network Layout refers to the visual arrangement of nodes and edges in a network map. Effective layouts enhance the clarity of network visualizations, making it easier to identify patterns, ...
