Practice question · Multiple choice
A word embedding places 'king' and 'queen' near each other in a 300-dimensional space. What is the vector space doing that a lookup table could not?
Hints
- A lookup table can say two words are related. Ask what it cannot say.
- What does the direction between two vectors represent here?
Show the answer
D. Making similarity computable, since meaning becomes geometry
Why
A table stores relationships you put in; a space lets you compute ones you did not. Distance gives similarity and direction encodes relation, so analogies fall out as arithmetic. That is why embeddings replaced hand-built thesauri, the structure generalises past what anyone enumerated.
