Network analysis

Basis of network analysis

• Graph theory

• Graphical theory

• Geography

What is graph theory?

• is the study of mathematical objects known as graphs, which consist of vertices connected by edges

• is the study of linear connections between logical sequence of objects

Training question: what is SNA?

• social network analysis

• spatial network analysis

• social network agglomeration

• spatial number analysis

What is social network analysis

• is the mapping and measuring of relationships and flows between entities

• is the graphical method for data analysis

• non-linear statistical analysis

• method of spatial data aggregation

Why do we use SNA?

• to examine the structure of social relationships in a group to uncover the informal connections between people

• to examines the lines between entities

• to estimate the influence of one spatial variable to another

• to predict the influence of one spatial variable to another

SNA methodology can be used as...

• unique perspective on how society functions

• prediction function

• correlation variable

• non-linear regression variable

How can we identify strong or weak ties in network?

• add weights to edges

• add edges to lines

• devide weak by strong

• devide strong by weak

How to identify key nodes?

• evaluate the location of actors in the network

• evaluate the actor nodes in the network

• evaluate the actors' weight in the network
