Lalmas, Ethan Zuckerman Finding News Curators in Twitter Janette Lehmann, Carlos Castillo, Mounia.This work was done in collaboration with Carlos Castillo, Mounia Lalmas, and Ethan Zuckerman. ![]() Hence, we proceed to compute a set of features for each user, and demonstrate that they can be used to automatically find relevant curators among the audience of two large news organizations. In this paper we describe how to find this specific class of curators, which we refer to as news story curators. We look at the users who shared a news story on Twitter and attempt to identify news curators who may provide more information related to that story. We adopt the perspective of a journalist or news editor who wants to discover news curators among the audience engaged with a news site. These users are news curators, and are the main subject of study of this paper. These users monitor a large variety of sources on a topic or around a story, carefully select interesting material on this topic, and disseminate it to an interested audience ranging from thousands to millions. There is a small but important group of users that devote a substantial amount of effort and care to this activity. Users interact with online news in many ways, one of them being sharing content through online social networking sites such as Twitter. This presentation is part of the SNOW workshop of the World-Wide-Web Conference, held in Rio to Janeiro, May 2013.
