The effective application of SNA can be detailed as follows: 1. Network Representation: - In online communities, individuals are represented as nodes, while interactions such as friendships, follows, or message exchanges are represented as edges. This basic structure allows for the visualization and analysis of the network's topology [1][3]. Depending on the platform, these networks can be directed or undirected, which influences the flow of information [5]. 2.
