论文摘要
在过去的几年中,所有社会都变得更加躁郁症,尤其是在在线社交网络和媒体出现之后。实际上,在新媒体传播之后,社会范围的两端之间的差距将更深。在这种情况下,社会两极分化一直是社会主义者和计算机科学专家的日益关注,因为在线社交网络通过为极端主义的火增加燃料会对社会产生有害的影响。进行了几种类型的研究,以提出措施来计算社交网络中的争议水平,之后,以减少矛盾的观点之间的争议,例如,通过将一方的意见暴露给对方成员。量化社交网络争议的大多数尝试都以其最初的形式考虑了这些网络,而没有任何属性。尽管这类研究提供了可用于不同社交网络的无平台算法,但它们无法考虑用户提供的大量有用信息(节点属性)。为了超越这一缺点,我们建议在具有不同属性的不同网络中使用一个框架。我们推动了一些有偏见的随机步行(BRW),以从起点到最初未知的终点找到起始节点的初始能量以及路径上节点的能量损失的路径。我们使用Node2VEC提取了网络的结构属性,并将其与最新算法进行了比较,并显示了其准确性。然后,我们提取了用户的一些内容属性,并分析了它们对算法结果的影响。将BRW与另一种最新的争议算法进行了比较。然后,它在波斯Twitter中的不同争议水平的变化被认为是在不同情况下的工作方式。
All societies have been much more bipolar over the past few years, particularly after the emergence of online social networks and media. In fact, the gap between the two ends of social spectrum is going to be even deeper after the spread of new media. In this circumstance, social polarization has been a growing concern among socialists and computer science experts because of the detrimental impact which online social networks can have on societies by adding fuel to the fire of extremism. Several types of research were conducted for proposing measures to calculate the controversy level in social networks, afterward, to reduce controversy among contradicting viewpoints, for example, by exposing opinions of one side to other side's members. Most of the attempts for quantifying social networks' controversy have considered the networks in their most primary forms, without any attributes. Although these kinds of researches provide platform-free algorithms to be used in different social networks, they are not able to take into account a great deal of useful information provided by users (node attributes).To surmount this shortcoming, we propose a framework to be utilized in different networks with different attributes. We propelled some Biased Random Walks (BRW) to find their path from start point to an initially unknown endpoint with respect to initial energy of start node and energy loss of nodes on the path. We extracted structural attribute of networks, using node2vec, and compared it with state-of-the-art algorithms, and showed its accuracy. Then, we extracted some content attributes of user and analyze their effects on the results of our algorithm. BRW is compared with another state-of-the-art controversy measuring algorithm. Then, its changes in different level of controversy in Persian Twitter is considered to show how it works in different circumstance.
