Characterizing Human Actions in the Digital Platform by Temporal Context

However, most human dynamic-behavior models focus only on the sequence of users' actions, abstracting the intervals between actions (i.e., inter-temporal information). Statistical time-series models, for instance, study the variation of values in the data over time; however, such models do not explicitly capture the interdependence between actions and their intervals. While some point-process models incorporate intervals, they use them to predict only a single or a few event types rather than to characterize diverse human actions enriched with temporal information from massive data (Zhao et al., 2015; Mei and Eisner, 2017). Therefore, in contrast with the sophisticated advancement of statistical behavior models, understanding human behavior from the perspective of inter-temporal context remains a difficult and often elusive goal. W e perform actions in many different contexts--from using smartphones to walking across campus. Studying these situations can help us understand what human actions are like. Even the same action can differ depending on when and where it happens. Time intervals between actions provide crucial contextual information, and much literature shows that they can reveal human cognitive states (Stanovich and W est, 2000; 1 arXiv:2206.09535v2
