Web-based evidence excavation to explore the authenticity of local events

ABSTRACT

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.
