interactionedges
Interactionedges are graph edges whose primary role is to represent interactions between nodes rather than merely indicating a connection. In network science, an interactionedge typically includes attributes that describe the nature, strength, and context of an interaction, such as type (communication, collaboration, chemical binding), weight (frequency or intensity), timestamp, and confidence.
Edges can be directed or undirected and may be weighted, sign-tagged (positive or negative interactions), and
Construction and representation: given a set of entities V, interactionedges are a subset of E ⊆ V×V
Analysis: measures focus on interaction strength, frequency, duration, and patterning, including edge-centric centrality, motif analysis, or
Applications span social networks (communications and influence), biological networks (protein-protein or gene regulatory interactions), ecological networks
