word2vec and negative sampling: how computers learn word meanings

word2vec is a small program that turns words into numbers so computers can sense meaning.
It was made by Mikolov and team, and changed how machines read text.
The trick called negative sampling helps the model learn fast without slow math.
Instead of comparing a word to all words, it checks a few wrong ones and a right one, and that teaches the model what fits.
The result are word embeddings, simple maps where similar words sit near each other.
You won't need to know equations to see why it works; examples do the job.
Many papers explained it in tough language, so people got lost, but the idea is friendly: give the computer many word pairs, show bad pairs too, and let it get better.
It's quick, clever, and widely used.
Try thinking about words as points in space, and negative sampling as nudges that pull right words closer and push wrong words away.
It feels like teaching by examples, simple and powerful.
