Mechanisms¶
- Inverted Index
- Ranking rides on top: a formula like BM25 scores each candidate by term rarity and frequency, so a ticket where "gateway" appears in the title outranks one where it appears once in a signature line.
This sourceDerives BM25 scoring from inverse document frequency and a saturating term-frequency contribution, with document-length normalization.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
