How this tag is built: every article in the archive is scored by cosine similarity against a centroid built from example sentences, and everything above 0.38 becomes a candidate. A model then reads each candidate and decides whether it belongs. The similarity shown on each row is what made it a candidate, not the reason it was kept.
