La production médiatique d’une « crise migratoire »
Bibliographic record
Abstract
Si le terme de « crise migratoire » s’est imposé dans le débat public pour qualifier les dynamiques de mobilités internationales en 2015, l’absence de modification brutale du système migratoire invite à chercher la crise dans sa représentation médiatique. S’appuyant sur des méthodes de lecture distante et sur une approche géographique, l’article propose une analyse des dynamiques spatio-temporelles de mise à l’agenda médiatique de la question migratoire dans un corpus de presse en ligne, mondial et multilingue. La variation dans le temps du flux d’information, relatif au fait migratoire, révèle des changements de régimes quantitatifs accompagnant des évolutions du contenu spatial des représentations de l’actualité migratoire (sélection et concentration des espaces couverts sur l’Union européenne et la Méditerranée orientale). Ces dynamiques conduisent à identifier l’émergence d’une crise géopolitique globale dans une démarche attentive à la production des imaginaires géographiques et aux changements d’échelle.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
