Artificial Intelligence / Unit 9 AI 0506 short lesson, about 20 seconds
Known by Its Company

The idea
The distributional idea holds that a word is known by the company it keeps — similar contexts, similar meanings, so context statistics can stand in for definitions.
In practice
"Rain" and "snow" share sentences about forecasts and boots; "flour" keeps different company entirely — no dictionary consulted.
Where people slip
Company records how people write, not how things are — the idea's power and its fingerprint share a root.
