Definitions for "Social network"
A social network is defined as a group of connections between two or more people based on any variety of relationships. The network connections we measure are based on kinship, labor exchanges, using the same rice mill, sharing agricultural equipment and temples. These networks mirror the way ideas or information flows between people, across households, and between villages. A typical social network is a kinship network, which are connections or ties based on relationships of blood or marriage. Other types of social networks are more loosely defined.
a collection of individuals linked together by a set of relations
