Dictionary antonyms measured

front is the dictionary opposite of backs, yet this model puts it closer than 7 of the 15 synonyms it can score. Opposites share the sentences a word lives in, so cosine alone cannot tell them apart - which is why the dictionary seeds this list rather than the geometry.

Shade shows how close the model puts each word to backs, 1 of 8 also appear in the dictionary. 15 of 24 dictionary synonyms are in this build; the rest have no vector to compare yet.
