1Hills, T. ; Segev, E.: ¬The news is American but our memories are - Chinese?.
In: Journal of the Association for Information Science and Technology. 65(2014) no.9, S.1810-1819.
Abstract: Are our memories of the world well described by the international news coverage in our country? If so, sources central to international news may also be central to international recall patterns; in particular, they may reflect an American-centric focus, given the previously proposed central U.S. position in the news marketplace. We asked people of four different nationalities (China, Israel, Switzerland, and the United States) to list all the countries they could name. We also constructed a network representation of the world for each nation based on the co-occurrence pattern of countries in the news. To compare news and memories, we developed a computational model that predicts the recall order of countries based on the news networks. Consistent with previous reports, the U.S. news was central to the news networks overall. However, although national recall patterns reflected their corresponding national news sources, the Chinese news was substantially better than other national news sources at predicting both individual and aggregate memories across nations. Our results suggest that news and memories are related but may also reflect biases in the way information is transferred to long-term memory, potentially biased against the transient coverage of more "free" presses. We discuss possible explanations for this "Chinese news effect" in relation to prominent cognitive and communications theories.
2Segev, E. ; Sheafer, T. ; Shenhav, S.R.: Is the world getting flatter? : A new method for examining structural trends in the news.
In: Journal of the American Society for Information Science and Technology. 64(2013) no.12, S.2537-2547.
Abstract: In this article, we propose a new method to analyze structural changes in networks over time and examine how the representation of the world in two leading newspapers, the New York Times and Der Spiegel, has changed during the past 50 years. We construct international networks based on the co-occurrences of country names in news items and trace changes in their distribution of centrality over time. Supporting previous studies, our findings indicate a consistent gap between the most central and the least central countries over the years, with the United States remaining at the center of the network and African countries at its peripheries. Surprisingly, the most dynamic changes in the past 50 years occurred in what we call the "middle range". In both outlets, we identified a trend of convergence, in other words, a more equal centrality of European, Middle Eastern, and Asian countries in the news. The implications of these findings are discussed.
3Segev, E.: Google and the digital divide : the bias of online knowledge.
Oxford : Chandos, 2010. XXXIV, 222 S.
(Chandos internet series)
Abstract: Aimed at information and communication professionals, scholars and students, Google and the Digital Divide: The Biases of Online Knowledge provides invaluable insight into the significant role that search engines play in growing the digital divide between individuals, organizations, and states. With a specific focus on Google, author Elad Segev explains the concept of the digital divide and the effects that today's online environment has on knowledge bias, power, and control. Using innovative methods and research approaches, Segev compares the popular search queries in Google and Yahoo in the United States and other countries and analyzes the various biases in Google News and Google Earth. Google and the Digital Divide shows the many ways in which users manipulate Google's information across different countries, as well as dataset and classification systems, economic and political value indexes, specific search indexes, locality of use indexes, and much more. Segev presents important new social and political perspectives to illustrate the challenges brought about by search engines, and explains the resultant political, communicative, commercial, and international implications.
