Cross-institutional duplicates
Which sheets in different countries came off the same plant?
- Status
- In development
- Field
- Thin — some prior work
- Who wants it
- Aggregators, repatriation and provenance work, deduplication.
Why it matters
One collection event was split and mailed to a dozen herbaria. Reuniting them builds a global collection-event graph — and for colonial-era collecting, a map of where a place's plants actually ended up.
What it needs
Visual matching plus collector-number matching. The harvest already carries a duplicate-cluster flag on a quarter of records.
State of the art
Record-level clustering exists at the aggregator. Image-level matching is thin.
