  Title Integrating Social Media into a Pan-European Flood Awareness System: A Multilingual Approach Type Conference Article
  Year 2019 Publication Proceedings of the 16th International Conference on Information Systems for Crisis Response And Management Abbreviated Journal Iscram 2019  
  Volume Issue Pages  
  Keywords Social Media, Disaster Risk Management, Flood Risk  
  Abstract This paper describes a prototype system that integrates social media analysis into the European Flood Awareness

System (EFAS). This integration allows the collection of social media data to be automatically triggered by flood

risk warnings determined by a hydro-meteorological model. Then, we adopt a multi-lingual approach to find

flood-related messages by employing two state-of-the-art methodologies: language-agnostic word embeddings

and language-aligned word embeddings. Both approaches can be used to bootstrap a classifier of social media

messages for a new language with little or no labeled data. Finally, we describe a method for selecting relevant and

representative messages and displaying them back in the interface of EFAS.

  Title Uneven Coverage of Natural Disasters in Wikipedia: The Case of Floods Type Conference Article
  Year 2020 Publication ISCRAM 2020 Conference Proceedings – 17th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal Iscram 2020  
  Volume Issue Pages 688-703  
  Keywords Social Media, News Values, Wikipedia, Natural Disasters, Floods.  
  Abstract The usage of non-authoritative data for disaster management provides timely information that might not be available through other means. Wikipedia, a collaboratively-produced encyclopedia, includes in-depth information about many natural disasters, and its editors are particularly good at adding information in real-time as a crisis unfolds. In this study, we focus on the most comprehensive version of Wikipedia, the English one. Wikipedia offers good coverage of disasters, particularly those having a large number of fatalities. However, by performing automatic content analysis at a global scale, we also show how the coverage of floods in Wikipedia is skewed towards rich, English-speaking countries, in particular the US and Canada. We also note how coverage of floods in countries with the lowest income is substantially lower than the coverage of floods in middle-income countries. These results have implications for analysts and systems using Wikipedia as an information source about disasters.
