Towards a Collection Data Approach to Crisis Situation Based on Ontologies

Disasters bring unforeseen situations to the public, requiring a quick and immediate response from official organizations. During these periods, access to rapidly changing information plays an important role in decision-making. However, the transmissions of information hinder this task and ultimately delay response operations. Social networks such as Twitter and Facebook create new opportunities to address this type of real-world problems. The involved actors use these channels at the time of crisis to share various information, whether they are requesting assistance, or describing an event. In this article, we will present the first steps of validation of a collect data approach from Twitter. This approach is based on a domain ontology.
