Dataset subset: MIST CANOPUS benchmark test set used in DreaMS Extended Data Table 1 (MIST CANOPUS retrieval split)

Sorted by Fingerprint cosine similarity (higher is better). The best value in each column is highlighted. Decimals are rounded for display; each value links to the printed value and its source.

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Evidence table

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
