Summary & Commant 4

Summay

This week, we learned about social networks. This week, we have lots of relationship map and friendster. There is an example of them. It is using CYWORLD. Someone draws relation map by analyzing cyworld users' relationship.

We specify social networks as science,technology,popular culture,and art.

- social networks as science:
field,definition,history,equivalence,centrality,bridges,social capital,
bowling alone.

Definition : It is just definition. It can be changed!.
History : There are many relation map.
Equivalence : If A and B is structurally equivalent, they have equivalent
positions in the network.
Centrality : center position in the network.
Bridges : like a bridge between boy and girl !
Social capital : bridging capital - Connecting separate networks.
bonding capital - Being central to a network.
Bowling alone : united states citizens no longer know or trust their eighbors
and thus communities have lost their social capital. It is so sad.

- social networks as technology : email, newsgroups, and weblogs / search engines.
- social networks as popular culture : Kevin bacon - bacon number.
- social networks as art : Relation map looks like a work of art!!
