Can embeddings be useful as a way to explore large corpora of historical data? Three recent conference papers: 1️⃣ doi.org/10.63744/R2L... Embeddings to analyze news collections (fig.1) 2️⃣ doi.org/10.5281/zeno... Media coverage analysis (fig.2) 3️⃣ doi.org/10.5281/zeno... UMAP vs. network viz? (fig.3)

Avec @martingrandjean.ch on présente bientôt un papier à Humanistica, et puisque j'ai illustré un exemple avec le cas de Charpentier, je me suis dit que c'était l'occasion de publier un billet de blog qui était "en attente" dans le back-office de mon carnet depuis 5 mois... ig.hypotheses.org/3980
