社交网络中协作内容生产的策略行为发现
Discovering Strategic Behaviors for Collaborative Content-Production in Social Networks
摘要：
一些社交网络提供明确的机制来分配社会奖励，例如基于用户活动的声誉，而其他网络中的机制则更加不透明。尽管如此，总有一些人比他们的同龄人获得更大的回报和声誉。一个直观但重要的问题是，这些成功的用户是否采用战略行为来变得有影响力。看起来，影响者似乎在玩弄这个系统。然而，由于组合策略空间、无法确定收益以及个人面临的资源限制等因素，仍然很难得出他们行动的合理性结论。这个问题的挑战性引起了理论界和数据采掘界的关注。因此，在本文中，我们的动机是调查，如果资源有限的个人发现与高回报的战略行为时，生产协作或互动内容在社交网络。我们提出了一个新的框架，动态双注意力网络或DDAN模型的内容生产策略的用户通过生成过程中，社会互动的影响下，参与的过程。大量的实验结果表明，我们的模型在建模用户行为的有效性。我们得出了三个强有力的经验发现。不同的策略会产生不同的社会收益，表现最好的个体对所发现策略的偏好表现出稳定性，这表明策略行为的出现，而策略偏好的稳定性与高收益相关。
英文摘要：
Some social networks provide explicit mechanisms to allocate social rewards such as reputation based on user activity, while the mechanism is more opaque in other networks. Nonetheless, there are always individuals who obtain greater rewards and reputation than their peers. An intuitive yet important question to ask is whether these successful users employ strategic behaviors to become influential. It might appear that the influencers have gamed the system. However, it remains difficult to conclude the rationality of their actions due to factors like the combinatorial strategy space, inability to determine payoffs, and resource limitations faced by individuals. The challenging nature of this question has drawn attention from both the theory and data mining communities. Therefore, in this paper, we are motivated to investigate if resource-limited individuals discover strategic behaviors associated with high payoffs when producing collaborative or interactive content in social networks. We propose a novel framework of Dynamic Dual Attention Networks or DDAN which models content production strategies of users through a generative process, under the influence of social interactions involved in the process. Extensive experimental results illustrate the effectiveness of our model in modeling user behavior. We make three strong empirical findings. Different strategies give rise to different social payoffs, the best performing individuals exhibit stability in their preference over the discovered strategies, which indicates the emergence of strategic behavior, and the stability of strategy preference is correlated with high payoffs.
