Pandemics are the greatest current threat to humanity. Many unidentified pathogens are already hiding out in the open, reported in local online media as sudden clusters of ‘influenza-like’ or ‘pneumonia-like’ clinical cases many months or even years before careful lab tests confirm a new microbial scourge. For some current epidemics like HIV, SARS, and H1N1, the microbial enemies were anonymously in our midst for decades. With each new infection, viruses and bacteria mutate and evolve into ever more harmful strains, and so we are in a race to identify and isolate new pathogens as quickly as possible.
Until now, no organization has succeeded in the task of tracking every global outbreak and epidemic. The necessary information is spread across too many locations, languages and formats: a field report in Spanish, a news article in Chinese, an email in Arabic, a text-message in Swahili. Even among open data, simple key-word or white-list based searches tend to fall short as they are unable to separate the signal (an outbreak of influenza) from the noise (a new flu remedy). In a project called EpidemicIQ, the Global Viral Forecasting Initiative has taken on the challenge of tracking all outbreaks. We are complementing existing field surveillance efforts in 23 countries with a new initiative that leverages large-scale processing of outbreak reports across a myriad of formats, utilizing machine learning, natural language processing and microtasking coupled with advanced epidemiological analysis.
EpidemicIQ intelligently mines open web-based reports, social media, transportation networks and direct reports from healthcare providers globally. Machine-learning and natural language processing allows us to track epidemic-related information across several orders of magnitude more data than any prior health efforts, even across languages that we do not ourselves speak. By leveraging a scalable workforce of microtaskers we are able to quickly adapt our machine-learning models to new sources, languages and even diseases of unknown origin. During peak times, the use of a scalable microtasking workforce also takes much of the information processing burden off the professional epidemic intelligence officers and field scientists, allowing them to apply their full domain knowledge when needed most.
At Strata, we propose to introduce EpidemicIQ’s architecture, strategies, successes and challenges in big-data to date.
