These visualizations provide a means of qualitatively assessing networks by varying the visual representation of their nodes and edges to reflect attributes of interest.Social network analysis has emerged as a key technique in modern sociology. These networks are often visualized through sociograms in which nodes are represented as points and ties are represented as lines. Examples of social structures commonly visualized through social network analysis include social media networks, memes spread, information circulation, friendship and acquaintance networks, business networks, knowledge networks, difficult working relationships, social networks, collaboration graphs, kinship, disease transmission, and sexual relationships. It characterizes networked structures in terms of nodes (individual actors, people, or things within the network) and the ties, edges, or links (relationships or interactions) that connect them. Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. Wikipedia (0.00 / 0 votes) Rate this definition:
