The vervet monkeys had moved out of their sleeping trees to forage on the ground. While the adults fed, the juveniles played in a nearby bush. Macauley, the rambunctious son of a lowranking female, wrestled Carlyle, the daughter of the highestranking female, to the ground. Carlyle screamed, chased Macauley away, and then went to forage next to her mother. Apparently the fi ght had been noticed ...

Social networks contain implicit knowledge that can be used to infer hierarchical relations that are not explicitly present in the available data. Interaction patterns are typically affected by users’ social relations. We present an approach to inferring such information that applies a link-analysis ranking algorithm at different levels of time granularity. In addition, a voting scheme is emplo...

Monkeys recognize the social relations that exist among others in their group. They know who associates with whom, for example, and other animals' relative dominance ranks. In addition, monkeys appear to compare types of social relations and make same/different judgments about them. In captivity, longtailed macaques (Macaca fascicularis) trained to recognize the relation between one adult femal...

Local community detection is an important research focus in social network analysis. Most existing methods share the intrinsic limitation of utilizing undirected and unweighted networks. In this paper, we propose a novel local community detection algorithm that fuses social relations and topic features in social networks. By defining a new social similarity, the proposed algorithm can effective...

this article employs a combination of direct observation method, online survey and focus group discussion techniques in order to study how social capital takes shape among youth facebook users in iran.  this article, will also, attempt to answer the question of whether the social capital that takes its roots from interaction between facebook users and friends' circles, will also reflect on...

We here present a fixed agents version of an original model of the emergence of hierarchies among social agents first introduced by Bonabeau et al. Having interactions occurring on a social network rather than among ’walkers’ doesn’t drastically alter the dynamics. But it makes social structures more stable and give a clearer picture of the social organisation in a ‘mixed’ regime.

Because people have different levels of engagement with each other, measuring social relations is difficult. In this work, we propose a method of measuring social relations with multiple datasets and demonstrate the differences with empirical evidence. Our empirical findings demonstrate that people use different communication media channels differently. Therefore, we suggest that in order to un...
