| Abstract | Social scientists have proposed many different factors thought to influence rumoring behavior. Classical rumor theory points to the perceived importance, the level of uncertainty or ambiguity, and the potential to impact decision making as influential in determining the extent of rumoring. In this work, we test some of these proposed rumor determinants in the context of the the 2010 Deepwater Horizon oil spill, using data on communication dynamics from the popular microblogging service Twitter. Using a latent factor model, we measure rates of hazard-related conversation by exploiting joint variation in multiple conversation streams. Time series analysis of the resulting rates suggests that media coverage of the event is a major driver of rumoring behavior, supporting importance/saliency theories and disconfirming theories of information substitution for this event. Relevance of the event to decision making behavior also turns out to be an influential predictor in this case. Since information diffusion via serial transmission is a fundamental process by which rumors spread, we compare rates of serial transmission between control and hazard-related communication. Twitter posts are much more likely to be retweeted when they contain hazard-related keywords (versus control words). Implications of these findings for disaster response are discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
