Heterogeneous Social Signals Capturing Real-world Disease Propagation

Increasing opportunities have been provided to collect massive social signals from varieties of human activity records than ever before, such as micro-blogging, information sharing, and geo-tagged activity logs in online social media platforms, with the help of technological advances in social sensing. This project focuses on using these signals and their associated geotags to infer the time and place of likely disease outbreaks, and to map disease risk across the country.

As specific examples, the figures below show the nation-wide detections of influenza like illnesses in Australia detected from Twitter (top), and the probability of an average individual to be at a point in 2-D space around their centre of gravity (bottom), based on their geo-tagged tweets.
