The Social Bow Tie

Nov

A recent study investigated a new way to identify the strength of ties. Using two different large datasets, the researchers found that for each pair of individuals, a bow tie structure of the network itself is strongly associated with the strength of ties between them that the researchers measure in other ways. The abstract of the paper is as follows: Understanding tie strength in social networks, and the factors that influence it, have received much attention in a myriad of disciplines for decades. Several models incorporating indicators of tie strength have been proposed and used to quantify relationships in social networks, and a standard set of structural network metrics have been applied to predominantly online social media sites to predict tie strength. Here, we introduce the concept of the “social bow tie” framework, a small subgraph of the network that consists of a collection of nodes and ties that surround a tie of interest, forming a topological structure that resembles a bow tie. We also define several intuitive and interpretable metrics that quantify properties of the bow tie. We use random forests and regression models to predict categorical and continuous measures of tie strength from different properties of the bow tie, including ...

The Strength of Absent Ties: Social Integration via Online Dating

31
Oct

by Josué Ortega and Philipp Hergovich We used to marry people to which we were somehow connected to: friends of friends, schoolmates, neighbors. Since we were more connected to people similar to us, we were likely to marry someone from our own race. However, online dating has changed this pattern: people who meet online tend to be complete strangers. Given that one-third of modern marriages start online, the authors investigate theoretically, using random graphs and matching theory, the effects of those previously absent ties in the diversity of modern societies. The authors find that when a society benefits from previously absent ties, social integration occurs rapidly, even if the number of partners met online is small. Their findings are consistent with the sharp increase in interracial marriages in the U.S. in the last two decades. Read the full article here.
