robin brunet asked 7 days ago

Bonjour, 
J’essaie de faire un simple réseau de collaboration entre auteurs. J’ai pour ça importé un csv avec une colonne auteurs et une colonne article. Chaque ligne est identifié par un couple article-auteur. Mais lorsque j’essaie de faire un mapping sur la colonne auteurs avec la mesure “raw” comme préconisé j’ai l’erreur suivante “469490” (voir log ci dessous pour les détails). J’ai essayé de faire ce qui est indiqué sur cette réponse : https://docs.cortext.net/question/network-mapping-error-the-network-you-produced-is-empty-please-review-the-choice-of-your-parameters-homogeneous-network-of-twitter-hashtags/ sans succès non plus. J’ai aussi essayé de mettre la mesure en automatique sans succès non plus. Je n’arrive pas à savoir si le problème vient du corpus ou du mapping.
Merci d’avance !
