PostDoc Job Offer : Tweet stream analysis for event detection and tracking The IDENUM project aims to follow events on twitter. It is a transdisciplinary regional project among computer science, information and communication science and industrial partners. The scientific objectives of the postoc is to create and develop methods to dynamically follow an event by reformulating the set of keywords to collect on Twitter.
