理解大型多关系社交网络中的协同进化

Understanding Co-evolution in Large Multi-relational Social Networks

Ayush Singhal, Atanu Roy, Jaideep Srivastava

摘要:

理解大型社交网络中的演化动力学是一个重要的问题。在本文中,我们描述了大型多关系社交网络的演化。Twitter、Facebook、Orkut和MMORPG \footnote{Massively Multi-player Online Role Playing Games}等在线媒体的激增创造了规模空前的社交网络数据。Sony的《Everquest 2》就是一个例子。我们利用博弈多关系网络,通过对博弈网络的宏观研究,揭示了多关系环境下的演化动力学。宏观分析涉及将网络分割成更小的部分,以研究这些称为“社区”的子网络内的动态。从多关系网络分析的进化视角,我们做出了以下贡献。具体来说,我们制定和分析了各种指标,以捕捉网络的进化特性。我们发现,在信任为基础的“社区”的共同进化率约$60\%$高于贸易为基础的“社区”。我们还发现,“社区”内部的信任和贸易联系随着其规模的增加而减少。最后,我们研究了动态的贸易和信任的“社区”内的相互关系,并发现有趣的结果之间的前体关系的贸易和信任动态的“社区”。

英文摘要:

Understanding dynamics of evolution in large social networks is an important problem. In this paper, we characterize evolution in large multi-relational social networks. The proliferation of online media such as Twitter, Facebook, Orkut and MMORPGs\footnote{Massively Multi-player Online Role Playing Games} have created social networking data at an unprecedented scale. Sony's Everquest 2 is one such example. We used game multi-relational networks to reveal the dynamics of evolution in a multi-relational setting by macroscopic study of the game network. Macroscopic analysis involves fragmenting the network into smaller portions for studying the dynamics within these sub-networks, referred to as `communities'. From an evolutionary perspective of multi-relational network analysis, we have made the following contributions. Specifically, we formulated and analyzed various metrics to capture evolutionary properties of networks. We find that co-evolution rates in trust based `communities' are approximately $60\%$ higher than the trade based `communities'. We also find that the trust and trade connections within the `communities' reduce as their size increases. Finally, we study the interrelation between the dynamics of trade and trust within `communities' and find interesting results about the precursor relationship between the trade and the trust dynamics within the `communities'.
