Another method is applied to the analysis of social network, refers to the social structure made up of individuals, which is connected in one or more specific types.
Social network analysis perspective, social network nodes and the relationship between the theory of. Node is individual actors in the network and the link is the relationship between the actors. The simplest form is a social network is a map designated relationship, such as friendship, between the nodes in a stage of study. Node, so the connection is a person's social interaction.
This example network is a 2-clique and 4-plex; {a, B and D} and {a, C, D} form factions. In this case, to all the other all the node, so they have the same effect within 4 slices. David is cut-point if delete, will make the network disconnected, and despair tie bridge, if delete, also can make the network disconnect. This example and degree and degree as a representative of the center of each node is as follows:
|

So the density of this network is 0.6; group level degree centrality is 0.5; and group degree centralization is 2/3. We can get the geodesic distances as follow matrix.

Then we could calculate the degree, betweenness
centrality, closeness
centrality, degree
centrality, degree prestige
and proximity
prestige of
each member and group
betweenness centralization, group
closeness centralization and group degree
centralization as follow. The group level
degree centrality is 0.5.
Backing to our question, we found that the degree centrality is the best to fit
the question, so using this to compute, we have the following results:

Matrix can show that David is the most prestigious, influence he of each attribute to maximize the value of, all of his property values greater than group concentrated attributes.
David degree high, value to send and receive many information to others a greater degree of influence and greater popularity and reputation in the network. Eva low value in-degree show that her a few sending and receiving text messages from the rest of the students. So she is often society and social isolation from the rest of the class.
In this network, d more adapted to prefer to have more structure and more consensually agree the structure; And E more innovation like operation using less structure and care for her in the structure of achieving consensus purposes. And full of Internet connection is A and D appear.
My work is finished, I found that, although different results, this paper, from the analysis of the same social network and the different methods, and they represent the same things in different ways. Different analysis methods just describe the role of the different nature, there are ways to achieve the same effect degree and degree of credibility, like to play closeness and close to the center reputation in this case.
