From the hash-bound evidence releases
Recorded claims
Each claim states what the inspected source says, at the recorded location—bounded by its scope and graded by its confidence. Nothing here is a synthesis across works.
A study of taxi drivers reports that AI route suggestions shortened cruising time and improved productivity for lower-skilled drivers, narrowing the productivity difference between lower- and higher-skilled workers in the studied setting.
Scope: publisher-deposited abstract metadata; worker productivity setting; sample denominator and study period are not stated in the captured abstract
Structured relationships
In-corpus citations
Only source-supplied cites relationships whose two endpoints are admitted are shown. Invocation evidence remains a separate relationship.
Boundaries
Limitations & independence
Recorded at coding time, carried with the work forever. A claim without its limits is not evidence.
Recorded limitations
- Abstract-level Crossref metadata only; the publisher landing page could not be retained because public retrieval was access-blocked.
- Crossref supplies only a year and month for publication, so published_date is null rather than an invented day.
- The abstract does not state the sample denominator or study period; no numerical effect-size claim is carried forward.
- Full text was not inspected.
Source independence
publisher-only
