Social Network Models and Data, EC'15 Tutorial

Social networks underly a broad range of social and economic research questions that are increasingly being understood through large-scale computational analyses. In particular, the study of social influence and information diffusion on social networks have rich modeling histories, while opportunities in online instrumentation and experimentations are now providing tremendous advances in our abilities for theory testing as well as theory development.
ukituki's insight:

 This tutorial will provide a brief overview of models of social networks and social influence, and then focus on giving an overview of recent evidence for how these processes behave empirically in diverse online settings. A particular emphasis will be placed on efforts to approach these problems through causal inference, moving beyond "big data" to "big experimentation".

Complex network study of Brazilian soccer players

Complex network study of Brazilian soccer players | Social Network Analysis #sna | Scoop.it
Although being a very popular sport in many countries, soccer has not received much attention from the scientific community. In this paper, we study soccer from a complex network point of view. First, we consider a bipartite network with two kinds of vertices or nodes: the soccer players and the clubs. Real data were gathered from the 32 editions of the Brazilian soccer championship, in a total of $13\phantom{\rule{0.2em}{0ex}}411$ soccer players and 127 clubs. We find a lot of interesting and p

The Rise of Twitter in the Political Campaign: Searching for Intermedia Agenda-Setting Effects in the Presidential Primary

The Rise of Twitter in the Political Campaign: Searching for Intermedia Agenda-Setting Effects in the Presidential Primary | Social Network Analysis #sna | Scoop.it
ukituki's insight:

Questions exist over the extent to which social media content may bypass, follow, or attract the attention of traditional media. This study sheds light on such dynamics by examining intermedia agenda-setting effects among the Twitter feeds of the 2012 presidential primary candidates, Twitter feeds of the Republican and Democratic parties, and articles published in the nation's top newspapers. Daily issue frequencies within media were analyzed using time series analysis. A symbiotic relationship was found between agendas in Twitter posts and traditional news, with varying levels of intensity and differential time lags by issue. While traditional media follow candidates on certain topics, on others they are able to predict the political agenda on Twitter.

ImmortalGraph: A System for Storage and Analysis of Temporal Graphs - Microsoft Research

ImmortalGraph is a storage and execution engine designed and optimized specifically for temporal graphs. Locality is at the center of ImmortalGraph’s design: temporal graphs are carefully laid out in both persistent storage and memory, taking into account data locality in both time and graph-structure dimensions. ImmortalGraph introduces the notion of locality-aware batch scheduling in computation, so that common “bulk” operations on temporal graphs are scheduled to maximize the benefit of in-memory data locality

The Social Contagion of Generosity

The Social Contagion of Generosity | Social Network Analysis #sna | Scoop.it
Why do people help strangers when there is a low probability that help will be directly reciprocated or socially rewarded? A possible explanation is that these acts are contagious: those who receive or observe help from a stranger become more likely to help others. We test two mechanisms for the social contagion of generosity among strangers: generalized reciprocity (a recipient of generosity is more likely to pay it forward) and third-party influence (an observer of generous behavior is more l

Analyzing R-Bloggers’ posts via Twitter | Social Network Analysis #sna | Scoop.it
For those who don’t know, every time a new blog post gets added to R-Bloggers, it gets a corresponding tweet by @Rbloggers, which gets seen by Rbloggers’ ~20k followers fairly fast. And every time my post gets published, I can’t help but check up on how many people gave that tweet some Twitter love, ie. “favorite”d or “retweet”ed it. It’s even more exciting than getting a Facebook “like” on a photo from Costa Rica!
