Abstract

It is often difficult to promptly perceive the extent of the consequences of a natural disaster when roads are cut, mobile phone is saturated, and the fragmentary information coming from the stricken area arrive at the drip. It is however on the basis of this diagnosis that must be organized the disaster management, relief, assistance to the victims, and the monitoring of the dynamic of the phenomenon. During natural disaster, social media, especially Twitter, sometimes remain one of the only source of in-situ information, as was the case just after the disastrous earthquake of Haiti in 2010. Some of the messages exchanged make it possible to get a clear idea of the consequences thanks to testimonies, photos or videos. It is with this in mind that we have developed a participatory platform for semi-automatic analysis of Twitter posts related to natural disasters. So-called “SURICATE-Nat”, this online Frenchspeaking platform (www.suricatenat.fr) aims to exploit informative messages posted on Twitter immediately during/after occurrence of natural disasters. This platform aims to structure and enrich the flow of raw data from Twitter into a human based instrumental stream that can then be analyzed as those coming from technological sensors (e.g. seismometers, GPS, piezometers, etc.). In addition, responding to willingness of Internet users to have an active “engagement” in the analysis of their own data, SURICATE-Nat offers participatory functionalities recognizing the value of “citizen expertise” and allowing each user to bring their own testimonies and take part in manual classification of tweets posted by others. This methodology aims to take advantage of the complementarity of artificial intelligence and participative approaches, in order to provide robust indicators for decision support.
