Source Selection

How a system decides which sources are worth using.

Industry Term

Full explanation

Source selection is how a search or AI system decides which of the available sources are relevant and trustworthy enough to use when constructing an answer.

Why this matters

It reframes the strategic question from how to rank to why a system would choose this source over another, which is a far more useful thing to work on.

Where this sits

Source Selection belongs to Retrieval, Evidence & Consensus, one of the seven layers of the Aingworth Glossary. Information exists, then it is retrieved, then sources are selected, then they corroborate one another, then consensus emerges. This is where Aingworth's Consensus Over Rankings thesis lives.
