    # EPITA IA INSTITUT ATELIER ## Useful informations ### Le 03/05 de 18H30 à 20H30: L’atelier se fera en distanciel mais nous serons tous au KB **Sujet :** « analyse de sentiment » Animateurs présents : Nathan, Clotilde et Gabriel ### Le 05/05 de 14H30 à 17H30 : L’atelier se fera en présentiel au KB **Sujet :** « analyse de sentiment » Animateurs présents : Nathan, Clotilde, Gabriel et Thomas ### Le 11/06 de 14H00 à 17H00 : L’atelier se fera en distanciel mais nous serons tous au KB **Sujet :** « visualisation des données » Animateurs présents : Nathan, Clotilde et Gabriel ## Analyse de sentiments ### Data Reviews sur des vins https://www.kaggle.com/datasets/zynicide/wine-reviews Reviews sur de la bouffe d'Amazon https://www.kaggle.com/datasets/snap/amazon-fine-food-reviews Reviews sur des fringues pour femmes de trucs d'e-commerce https://www.kaggle.com/datasets/snap/amazon-fine-food-reviews ### Organisation de l'atelier #### Avec les mains Définir la problématique, de quoi parle-t-on? Qu'entend-on part "Analyse de sentiments"? Quel est l'intérêt d'étudier la question? (voir https://www.youtube.com/watch?v=4x7ah-erKiw) Analyse des sentiments = déterminer l'intention (content / pas content) derrière un commentaire, un avis, une phrase Comment on pourrait faire ça? => Séance de questions / réponses et d'interactions avec les étudiants - smileys - ponctuation (ironie, colère, ...) - adjectifs qualificatifs (bien, mauvais, ...) - verbes de "goûts" (j'aime, je deteste, ...) - adverbes (très, peu, ...), peut servir à faire une échelle plutôt qu'un truc binaire sentiment positif / négatif - négation ou non (pas mauvais -> positif) - ... Le but est d'orienter vers le plus simple au début et de mettre en avant les difficultés que soulève chaque remarque, genre l'utilisation pas DU TOUT universelle de chaque smiley, ou de la ponctuation (rebondir leur propre utilisation par sms d'un smiley par exemple) #### Mise en situation avec le code Commencer par un systeme tres simple de score de positivité par mot Probleme: "ce n'est pas mauvais" serait associé a une phrase negative. Comment tester la méthodo? -> Trouver une database et regarder les résultats Methode Vader ensuite ## Repartition des tâches - [x] Host Jupyter (Clou) - [ ] Host le CSV (le lien du file est sur Discord) (Clou) - [ ] PowerPoint (Clou & Tomate) - [ ] Kahoot (Tomate) - [ ] Construction atelier (Thomas) - [ ] Ecriture code python (Gab) - [ ] Pédagogiser le python intro (Gabitche)
