David Chavalarias (CNRS): Multiscale and multi-level reconstruction of knowledge dynamics : a new window on collective phenomena

In 1751, Jean le Rond d’Alembert had a dream: “to make a genealogical or encyclopedic tree which will gather the various branches of knowledge together under a single point of view and will serve to indicate their origin and their relationships to one another”. Three hundreds years later, the digitalization of human activities and its outputs has made text-strings a universal medium for addressing knowledge production in domains as diverse as academia, biomedical research or online citizen debates. We will develop the notion of “branches of knowledge” envisionned by d’Alembert and propose a reconstruction method that makes it possible to reconstruct, from unstructured textual materials, a multi-level and multi-scale representation of these branches of knowledge. We will then investigate the new relationships that this type of reconstruction allows to establish with collective phenomena by using several applications of this method such as scientific publications, Twitter data or clinical trials.
