# Enrichment Review — 10 LLM-Assisted Results

Query: `type=confiscation, date=1933–1945`. Generated 2026-03-28.

## About this page

Some provenance records in these results were enriched or classified by an LLM (large language model) because the provenance parser could not resolve them from text alone. Each enrichment below shows the method used and the LLM's reasoning for its decision. Methods include type/category classification, party disambiguation, validated deterministic rules, and structural corrections (location fixes, phantom event removal, event splitting).

These classifications are automated and have not been individually verified or endorsed by the Rijksmuseum. The reasoning is provided for transparency so you can assess the quality of each decision.

## Task description

The provenance parser automatically extracts structured ownership events from free-text provenance records written in the AAM (American Alliance of Museums) standard. It uses rule-based pattern matching to identify transfer types, parties, dates, locations, and prices. When the rules cannot resolve an event — for example, a bare name with no transfer keyword, or a merged party text that needs decomposition — an LLM (large language model) is used with art-historical domain context to make the classification. Every LLM decision is recorded with its method and reasoning for full traceability.

7 of 8 resolved deterministically, 1 with LLM enrichment
LLM disambiguated Event 5, "Fritz Mannheimer estate" → `sender`
[rename] This is an anaphoric reference 'whose estate' referring back to Fritz Mannheimer from event 4. The phrase 'from whose estate purchased' indicates the estate as the sender/consignor in this confiscation event. The 'from' and 'purchased' are verb phrases that should be stripped to leave just the party name. | Original: "from whose estate purchased" → Fritz Mannheimer estate [sender]

Enrichments (2 events, 4 parties)
5 of 10 resolved deterministically, 5 with LLM enrichment
LLM classified Event 2 → `sale`
The preceding context shows this is part of a sale at Sotheby's (May 22, 1928, no. 77). The price '£20' and 'to Dussler' indicates this is the purchase by Dussler at that auction.
LLM classified Event 4 → `confiscation`
In 1940 wartime context, 'from his employees' to Alois Miedl with a large sum (fl. 2,500,000) suggests coerced wartime acquisition. Miedl was a known Nazi art dealer who acquired Jewish collections during WWII. This appears to be forced wartime confiscation from Goudstikker's business.
LLM disambiguated Event 4, "[Goudstikker employees]" → `sender`
[rename] The phrase 'probably from his employees' contains the preposition 'from' which indicates direction but isn't part of the party name. 'His employees' refers to Jaques Goudstikker's employees from the previous event (event 3), who likely acted on behalf of the Goudstikker business/estate during the 1940 confiscation period. This is one party (the employees as a group) acting as sender, not multiple parties. | Original: "probably from his employees" → [Goudstikker employees] [sender]
LLM classified Event 7, "back to Alois Miedl" → `unknown`
'back to Alois Miedl' indicates Miedl is receiving the artwork again (returning to his possession after the failed auction). The word 'back' and 'to' clearly indicate he is the receiver in this return transfer.
LLM classified Event 9, "Mr. L. de Ruyter before 1975" → `unknown`
Following AAM bare-name convention, 'Mr. L. de Ruyter before 1975, Jutphaas' indicates de Ruyter held the artwork before 1975. The location and temporal qualifier establish him as the holder/owner, making him the receiver in this event.
LLM classified Event 10, "museum" → `receiver`
Extracted from event text: receiver "museum" found in "to the/to [Name]" pattern. Parser's parseRest() missed this tail party.

## RP-P-2023-55 — Portret van schrijfmeester Hendrick Persijn

Gerrit Gauw (mentioned on object)
Provenance chain (LLM-enriched events highlighted)

- 1. [confiscation] 1939 Zentralstelle für Denkmalschutz, Vienna, after April 1939 and before December 1940
- 2. [sale] 1990 Unknown sale (possibly Van Stockum, The Hague, or Van Gendt, The Hague), c. 1990’s, to private collector
- 3. [sale] 2023 {According to an oral remark of the collector.} from whom to the museum, 2023

Enrichments (1 event, 2 parties)
1 of 3 resolved deterministically, 2 with LLM enrichment
LLM classified Event 1 → `confiscation`
The Zentralstelle für Denkmalschutz was the Nazi Austrian authority for cultural protection/looting during WWII. The timing (after April 1939, when Germany annexed Austria) and the export stamp mentioned in the citation strongly indicate this was Nazi confiscation of cultural property, not a normal collection event.
LLM classified Event 1, "Zentralstelle für Denkmalschutz" → `unknown`
The Zentralstelle für Denkmalschutz was the Nazi authority responsible for controlling cultural property exports from Austria after the Anschluss. In this context, they received/confiscated the artwork from its previous owner. The transfer_type is already identified as 'confiscation', confirming they acquired the artwork through seizure.
LLM classified Event 2, "private collector" → `receiver`
Extracted from event text: receiver "private collector" found in "to the/to [Name]" pattern. Parser's parseRest() missed this tail party.
