Web-based evidence excavation to explore the authenticity of local events
Ryong Lee, Daisuke Kitayama, Kazutoshi Sumiya · 2008
With the increasing employment of the Web in our daily lives, we often use it to find evidence of real-world events. The difference with normal web searches is that users want to reveal whether an event is true or false based on firm facts. In this paper, we propose a model to excavate real-world events from the Web, to manage the vestige in spatio-temporal space and to offer users reliable evidence of an event. We also describe a similarity measure between events to perform searching and clustering. A credibility estimation method, based on the trustworthiness of events and the authority of web sites, using a primary experiment is also presented.
