linked-jazz-2026-qa

Compares the relationships people asserted in the original Linked Jazz project (base.semlab.io Wikibase: 52nd Street crowdsourcing + supervised name tagging) with the LLM/audit relationships in ~/git/ch-jazz-mashup/linked_jazz.sqlite, on the 46 transcripts both corpora share (Hamilton College, Smithsonian, Rutgers).

• REPORT.md — findings.
• site/index.html — explorer (open directly in a browser; data embedded in site/data.js). Published at https://semanticlab.github.io/linked-jazz-2026-qa/ via GitHub Pages (.github/workflows/pages.yml deploys site/ on every push to main).

# 1. transcript list + property labels (SPARQL; small queries only, bulk ones 524 behind Cloudflare)
curl -sG -A semlab-data-process "https://query.semlab.io/proxy/wdqs/bigdata/namespace/wdq/sparql" -H "Accept: text/csv" --data-urlencode 'query=...' > semlab_transcripts.csv
# 2. SQLite interviewees of the three archives (sqlite_interviewees_rhs.txt), then:
uv run python harvest_semlab.py     # wbgetentities API, cached in raw/entities/ -> data/semlab_harvest.json
uv run python harvest_reverse.py    # statements on object items (found none)
uv run python extract_sqlite.py     # -> data/sqlite_side.json

Wikibase layout (for reference)

• transcript item: P1 instance of Q1960 (interview transcript), P13 interviewee, P14 interviewer, P15 source (Q2031 Hamilton College, Q2033 Smithsonian, Q2034 Rutgers, Q2032 U. Michigan, Q21579 Weeksville), P16 legacy MD5, P7 slug, P98 date.
• block item: P1 = Q2013, P24 parent transcript, P17 local id, P19 text, P20 text URL (semlab.s3.amazonaws.com/texts/<md5>/<n>.txt), P23 speaker, P21 associated entities.
• relationship statements live on the interviewee's person item (P29 knows of … P39 influenced by), qualified by P25 generation method (Q18800 supervised NER, Q18801 crowdsourced 52nd St) and P40 user consensus, referenced by P26 block items.
