Real-time event extraction for infectious disease outbreaks
Ralph Grishman, Silja Huttunen, Roman Yangarber · 2002
We describe a system for creating and automatically updating a data base of information on infectious disease outbreaks. A web crawler is used to retrieve current news stories; potentially relevant stories are fed to an information extraction engine, whose output is used to update the data base. A web-based browser allows users to examine the data base and select records based on date, disease, location, and other fields. The browser can also display the source text from which the data base information is derived.
