Two sentence embeddings have a high cosine similarity. What does this suggest?
Why B is the answer
Similar meaning
Embedding similarity reflects meaning, not length, authorship or storage.
In detail
- High cosine similarity suggests similar meaning.
- Cosine compares direction, not length.
Use case
An illustrative scenario, not a real incident.
"How do I reset my password" and "I forgot my login" have a high cosine similarity, though they share few words.

Q -->|"High cosine similarity"| A0["Similar meaning"]
Q -->|"Low cosine similarity"| A1["Different meaning"]Key point: High cosine similarity suggests similar meaning.
Why the other options are wrong
- A. They are stored close together on the disk
- Disk location is unrelated.
- C. They hold exactly the same number of tokens
- Token count is unrelated.
- D. They were written by the same person
- Authorship is unrelated.
