短时间尺度上的社会行为通常被理解为行动，可以被认为是离散事件，其中一个个体针对他或她环境中的一个或多个其他实体（可能包括他自己）发出行为。在这里，我们引入了一个高度灵活的框架，在社会环境中的行为建模，它允许基于似然性的推理与复杂的依赖行为机制。实例给出了参数化的基础活动水平，近因，持久性，优先附件，传递/循环的相互作用，参与关系事件框架内的转变。参数估计讨论的数据中，只有事件序列是已知的。该框架的效用说明了通过应用程序的响应者无线电通信在世界贸易中心灾难的早期动态建模。
Social behaviour over short time scales is frequently understood in terms of actions, which can be thought of as discrete events in which one individual emits a behavior directed at one or more other entities in his or her environment (possibly including himself or herself). Here, we introduce a highly flexible framework for modeling actions within social settings, which permits likelihood-based inference for behavioral mechanisms with complex dependence. Examples are given for the parameterization of base activity levels, recency, persistence, preferential attachment, transitive/cyclic interaction, and participation shifts within the relational event framework. Parameter estimation is discussed both for data in which only event sequences are known. The utility of the framework is illustrated via an application to dynamic modeling of responder radio communications during the early hours of the World Trade Center disaster.
