“Occupy Wall Street (OWS) is an ongoing series of demonstrations initiated by the Canadian activist group Adbusters which began September 17, 2011 in Zuccotti Park, located in New York City‘s Wall Street financial district. The protests are against social and economic inequality, high unemployment, greed, as well as corruption, and the undue influence of corporations—particularly from the financial services sector—on government. The protesters’ slogan We are the 99% refers to the growingdifference in wealth in the U.S. between the wealthiest 1% and the rest of the population.” (cited from wikipedia)


Online Social Movement

I study it as one online social movement, and aims to uncover the structural pattern of the interactions.


The data are collected by R-shief, and was open to the world by registration. The data contains 1353413 tweets between Sep 24th 2011 and Oct 10th 2011, among which, there are 88601 interactions.

I have been working on this piece of data and finding interesting temporal patterns among twitting and retwitting behavior in terms of action and interaction.


3923 twitter users spoke to others  in Sep 24. Apparently, there are cores and periphery.

The power Law Distribution above confirms such proposition.
