WebMotifs. Network motifs are repeated graphlets (small subgraphs of a larger network that appear at any frequency) in a specific network capturing particular patterns of interactions between vertices. They are often associated with particular functions (Stone et al., 2024) and are used for many applications in biological networks (Kim et al ... WebFrom social science to biology, numerous applications often rely on motifs for intuitive and meaningful characterization of networks at both the global macro-level as well as the local micro-level.
