Social network analysis (SNA) is a method used to study the relationships and structures within social networks. It involves mapping and measuring the connections between individuals, groups, or organizations, often represented as nodes and edges in a graph. This analysis helps identify patterns, influences, and the flow of information within a network. SNA is applied in various fields, including sociology, psychology, and business. By understanding how entities interact, researchers can gain insights into social dynamics, identify key players, and improve communication strategies. This approach is valuable for enhancing collaboration and addressing issues within communities or organizations.
