위키디피아의 사회네트워크 정의

 

국어

소셜 네트워크(Social Network 또는 social graph)는 웹 사이언스의 연구 분야 중 하나로, 웹 상에서 개인 또는 집단이 하나의 노드(node)가 되어 각 노드들 간의 상호의존적인 관계(tie)에 의해 만들어지는 사회적 관계 구조를 말한다.

모든 노드들은 연결망(netwotk) 안에 존재하는 개별적인 주체들이고, 타이(tie)는 각 노드들 간의 관계를 뜻한다.

소셜 네트워크 분석(Social Network Analysis)은 수많은 노드들과 그 노드들 사이의 무수히 다양한 관계들로 인해 계산론적으로 접근하기에 매우 복잡한 분야이다.

소셜 네트워크에 대해서는 현재 인문, 경제, 공학 등 다양한 분야에서 많은 연구가 진행되고 있다.

A social network is a social structure made of individuals (or organizations) called "nodes," which are tied (connected) by one or more specific types of interdependency, such as friendship, kinship, financial exchange, dislike, sexual relationships, or relationships of beliefs, knowledge or prestige.

Social network analysis views social relationships in terms of network theory about nodes and ties. Nodes are the individual actors within the networks, and ties are the relationships between the actors. The resulting graph-based structures are often very complex. There can be many kinds of ties between the nodes. Research in a number of academic fields has shown that social networks operate on many levels, from families up to the level of nations, and play a critical role in determining the way problems are solved, organizations are run, and the degree to which individuals succeed in achieving their goals.

In its simplest form, a social network is a map of all of the relevant nodes between all the nodes being studied. The network can also be used to measure social capital -- the value that an individual gets from the social network. These concepts are often displayed in a social network diagram, where nodes are the points and ties are the lines.
