Embeddings
A way of turning text — or images — into a long list of numbers that captures its meaning, so a computer can measure how similar two things are. Pieces with close meanings end up with close numbers, even when they share no words: 'car' and 'automobile' land near each other; 'car' and 'banana' land far apart. This is the trick that makes 'search by meaning' possible instead of just matching exact keywords.
