Can a flow of information across Twitter signal when a momentous event is about to occur?

Northeastern University researchers are working with a group of scientists to develop a method to map how tweets about large-scale social events spread.

Knowing the characteristics of that buildup could enable researchers to prepare ahead of time for undesirable repercussions from such events, says Nicola Perra, a former research asso­ciate at Northeastern's Net­work Sci­ence Insti­tute.

"What we are trying to under­stand is the pres­ence of pre­cur­sors: can we find a signal in the flow of infor­ma­tion that will tell us some­thing big is about to happen?" asks Northeastern professor Alessandro Vespig­nani.

The researchers used network modeling in neuroscience to conduct the study, having nodes represent cities and the links represent the pathways the tweets take over time.

For example, in 2011, Spanish protests sparked the Occupy Wall Street movement in the U.S., and the tweets gained in volume and intensity until they reached a "social tipping point of collective phenomenon" on May 20, 2011.

"You create a system that starts from a few nodes that then drive others, and so on, until every­body is talking to every­body else in a full coor­di­na­tion of the infor­ma­tion," Vespignani says.

The researchers focused their study on the 2011 protest in Spain, the Brazilian Autumn protest in 2013, the release of a Hollywood blockbuster movie in 2012, and Google's acquisition of Motorola in 2014.
