Excellent paper proposing "a richer class of Entity Interaction Network models" and defining "a checklist of features that can help build such a model." In particular, instead of using "simple models, such as node–and–edge graphs," the model "provides facilitates assigning 'meaning' to its nodes and links. These nodes and links should have 'types'." The model is extended to include node properties and edge properties, which can be incorporated as part of description of a network. The model also considers data collection techniques and ambient factors such as the data decay. The model is applied to Twitter, Facebook and YouTube.
