Salton, Wong and Yang: vector-space model for automatic indexing

What changed

Formalized document/query vector geometry and tested vocabulary-density implications.

Scientific scope

The record is the exact three-author 1975 Communications of the ACM paper. It does not absorb all term-weighting schemes, later cosine-ranking conventions, probabilistic retrieval or modern embeddings.
