Iscram Summer School 2009 From Mashups To Modelling (Tom De Groeve)

864

Published on

Large catastrophes often trigger international humanitarian response. This is a particular context in which many independent actors, including governmental agencies (e.g. search and rescue teams), non-governmental organizations (NGO’s such as Doctors Without Borders), corporations (e.g. Google or Microsoft) and international organizations (including the United Nations Office for Coordination of Humanitarian Affairs) work together to provide first response and subsequent relief and reconstruction assistance. In the absence of a clear command and control structure, situational awareness needs to be acquired by each actor independently. Needless to say that this community is eager to develop and use technology and systems to acquire and share information, and that collaboration and information sharing is generally considered as mutually benefitting.
In the early onset of disasters, information is sparse. Traditionally, there are three main sources of information: scientific monitoring systems (e.g. seismological or meteorological networks), official information (briefings by the local emergency management agency) and media reports. Information management for each source requires different technological solutions, respectively focused on modelling, web portals for information sharing, and linguistic processing. However, more recently a fourth source of information is becoming available through Web 2.0: information from citizens, sometimes labelled crowd-sourcing. In case of a disaster, local (and remote) citizens can and do provide information (e.g. eyewitness reports) or analysis (e.g. compiling reports in an information feed). However, this fourth source is not widely used yet by emergency managers because the reliability of the information is not well understood and hard to assess in a time-critical environment.

  93. 93. What is MedISys?<br />MedISys (Medical Information System) is a real-time news alert system for medical and health-related topics. <br />MedISys: <br />processes over 20000 articles per day from over 4000 sites of approximately 1600 news sources (news and medical sites) in 45 languages, <br />dynamically updates statistics on all news topics every 10 minutes, <br />categorises articles in pre-defined medical topics in 25 different languages, <br />How does it work?<br />MedISys turns news into a signal. Over time stories come into the news then gradually disappear. Some topics appear regularly whereas other topics occur infrequently. MedISys keeps track of these topics comparing current news events with those in the past in order to quickly identify breaking news. <br />What does MedISys offer over other news providers?<br />The system uses dynamic statistical modelling techniques to: <br />suppress news noise, i.e. stories that are regularly in the news,<br />enhance stories with a poor signal, and<br />identify individual events on a temporal and locational basis.<br />Visit to NERSS, 29-30 July 2009<br />
