has the advantage of precision — it’s useful in keyword search, for instance, if you know the document you want, and you know its exact title.
The key insight, made at the beginning of the information age, is to replace word meaning with something that machines can actually measure.

So the machine can learn which words are related by processing text, sentence by sentence, and seeing which words occur together.
These vectors live in a very high dimensional vector space, but we can use dimension reduction to make this representation more robust andtractable.
