Testing a model of witness accounts in social media

Content Provider ACM Digital Library
Author Winter, Stephan Vasardani, Maria Truelove, Marie
Abstract Identifying micro-bloggers who are likely witnesses to events is beneficial in numerous applications, including event detection and credibility assessment. This paper presents research in-progress on testing of a conceptual model, which defines witness and related accounts from micro-blogs about events. The case study events considered have varying spatial and temporal characteristics, and include a shark sighting, a music concert, a protest, and a cyclone. Results indicate that witnessing characteristics are influenced by numerous factors in addition to the spatial and temporal characteristics of the events, including the motivation of the witnesses themselves. Additionally, the results suggest enhancements to the conceptual model to provide a more sophisticated generic implementation, and insights for future automation approaches.

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.
