Modeling collaboration processes is a challenging task. Existing modeling approaches are not capable of expressing the unpredictable, non-routine nature of human collaboration, which is influenced by the social context of involved collaborators. We propose a modeling approach which considers collaboration processes as the evolution of a network of collaborative documents along with a social network of collaborators. Our modeling approach, accompanied by a graphical notation and formalization, allows to capture the influence of complex social structures formed by collaborators, and therefore facilitates such activities as the discovery of socially coherent teams, social hubs, or unbiased experts. We demonstrate the applicability and expressiveness of our approach and notation, and discuss their strengths and weaknesses.

对协作过程进行建模是一项艰巨的任务。现有的建模方法无法表达人类协作的不可预测，非常规性质，这受相关协作者的社会环境影响。我们提出一种建模方法，该方法将协作过程视为协作文档网络以及协作者社交网络的演进。我们的建模方法以及图形符号和形式化方法，可以捕获由协作者形成的复杂社会结构的影响，因此可以促进诸如发现具有社会凝聚力的团队，社交中心或公正的专家之类的活动。我们展示了我们的方法和符号的适用性和表达性，并讨论了它们的优缺点。
