Special Lecture (19) : Second level gatekeeping and Content Concentration in Twitter: An Analysis of the 2009 Gaza Conflict By Prof. H. Raghav Rao SUNY Distinguished Service Professor Management Science and Systems Department, University at Buffalo,State University of New York, USA
January 16, 2012
International School of information Management (ISiM) has organised a Special Lecture (19) on “Second level gatekeeping and Content Concentration in Twitter: An Analysis of the 2009 Gaza Conflict” by Prof. H. Raghav Rao, SUNY Distinguished Service Professor, Management Science and Systems Department, University at Buffalo, State University of New York, USA, on 16th January, 2012 at 11:00 am @ International School of information Management (ISiM), Manasagangotri, Mysore.
Twitter is a social news site in which various types of information are re-circulated and reinterpreted by individual users. The talk will provide an overview of a research study conducted by Hazel Kwon, Onook Oh, Manish Agrawal and H. R. Rao. The research study explores the pattern of Twitter users’ selection of news contents, defining their practice as the ‘second-level’ gatekeeping. By analyzing user-selected contents in Twitter about the 2009 Israel-Gaza conflict, the study finds: first, while a variety of contents were selected and redistributed by Twitter users, the aggregation of these selections over-represents a small number of prominent content providers; second, Twitter users’ selection is not constituted randomly, affected by hyperlinks structure and content types; third, temporal analyses revealed that social media sites and traditional media are prominently selected in a later stage of news lifespan.
