The binary counting method is especially suited for large texts and prevents that term maps are skewed by a single term appearing frequently within one document. it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/604c863522e44a51184b78d7/1631257911116-59500X4WP1WKUQAYXZKB/map_articles_before_binary.png Portfolio -
