First Workshop on Social News on the Web, Rio de Janeiro, Brazil, May 13th, 2013.
We present a data-driven study on which sources were the
rst to report on news events. For this, we implemented a
news-aggregator that included a large number of established
news sources and covered one year of data. We present a
novel framework that is able to retrieve a large number of
events and not only the most salient ones, while at the same
time making sure that they are not exclusively of local impact.
Our analysis then focuses on di erent aspects of the news
cycle. In particular we analyze which are the sources to
break most of the news. By looking when certain events
become bursty, we are able to perform a ner analysis on
those events and the associated sources that dominate the
global news-attention. Finally we study the time it takes
news outlet to report on these events and how this re
di erent strategies of which news to report.
A general nding of our study is that big news agencies
remain an important threshold to cross to bring global attention
to particular news, but it also shows the importance of focused (by region or topic) outlets.
