Journée scientifique

Fouille de texte en biologie

ADN

Le PPF Bioinformatique organise une journée scientifique sur les applications de la fouille de texte à la biologie : extraction d'information en génomique,inférence des interactions géniques...seront à l'ordre du jour.

  • Date : 20/09/2011
  • Lieu : Amphithéatre du batiment IRI-IRCICA, campus CNRS
  • Organisateur(s) : PPF Bio-informatique

La journée se tiendra dans l'amphithéatre du batiment IRI-IRCICA, de 9h45 à 17h00 .

Mikaela Keller , membre de l'équipe-projet Inria Mostrare et de de l'Université Lille 3 interviendra sur la découverte du vocabulaire automatisé pour l'analyse de la géo-information sur les épidémies en ligne.

Résumé

Automated vocabulary discovery for geo-parsing online epidemic intelligence  
 
Automated surveillance of the Internet provides a timely and sensitive method for alerting on global emerging infectious disease threats. HealthMap is part of a new generation of online systems designed to monitor and visualize, on a real-time basis, disease outbreak alerts as reported by online news media and public health sources. HealthMap is of specific interest for national and international public health organizations and international travelers. A particular task that makes such a surveillance useful is the automated discovery of the geographic references contained in the retrieved outbreak alerts. This task is sometimes referred to as "geo-parsing". A typical approach to geo-parsing would demand an expensive training corpus of alerts manually tagged by a human. Given that human readers perform this kind of task by using both their lexical and contextual knowledge, we developed an approach which relies on a relatively small expert-built gazetteer, thus limiting the need of human input, but focuses on learning the context in which geographic references appear. We show in a set of experiments, that this approach exhibits a substantial capacity to discover geographic locations outside of its initial lexicon.
