论文摘要

一些社交网络提供了明确的机制来分配基于用户活动的声誉等社交奖励,而在其他网络中该机制则更不透明。尽管如此,总会有些人比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发挥影响力。看来有影响力的人已经赋予了系统。但是,由于组合战略空间,无法确定收益以及个人面临的资源限制,因此很难结论其行动的合理性。这个问题的挑战性质引起了理论和数据挖掘社区的关注。因此,在本文中,我们有动力调查资源有限的个人是否发现与社交网络中产生协作或互动内容相关的战略行为。我们提出了一个动态双重注意网络或DDAN的新型框架,该框架在过程中涉及的社交互动的影响下,通过生成过程对用户的内容生产策略进行建模。广泛的实验结果说明了我们模型在对用户行为进行建模的有效性。我们做出了三个有力的经验发现。不同的策略引起了不同的社会收益,表现最好的个人在偏爱发现的策略方面表现出稳定,这表明战略行为的出现,战略偏好的稳定性与高收益相关。

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.
