Next Steps: Conversation JSON Extraction
Status: ✅ Phase 2A COMPLETE - Pattern-Based Extraction Working
Priority: HIGH
Complexity: Medium (Pattern-based completed, ML-based enhancement optional)
Last Updated: 2025-11-05
✅ COMPLETED: Pattern-Based NLP Extractor
Implementation: src/glam_extractor/extractors/nlp_extractor.py (630 lines, 90% test coverage)
Capabilities:
- ✅ Institution name extraction (pattern-based with keyword detection)
- ✅ Multilingual support (English, Dutch, Spanish, Portuguese, French, German, Greek)
- ✅ Institution type classification (13 types: MUSEUM, LIBRARY, ARCHIVE, etc.)
- ✅ Identifier extraction (ISIL, Wikidata, VIAF, KvK)
- ✅ Location extraction (city, country from patterns)
- ✅ Confidence scoring (0.0-1.0)
- ✅ Full provenance tracking (TIER_4_INFERRED)
- ✅ Deduplication
Batch Processing Pipeline: scripts/batch_extract_institutions.py (500+ lines)
Test Results:
- 21 tests, 20 passing (95% pass rate)
- Successfully tested on 3 conversation files
- Extracted 18 unique institutions from test run
- Exports to JSON and CSV formats
Known Limitations (Pattern-Based Approach):
- Name variants ("Vietnamese Museum" vs "Vietnamese Museu")
- Many institutions have UNKNOWN country (location patterns limited)
- Complex names fail ("Museum of Modern Art" not matched by simple patterns)
- No syntactic parsing, relies on keyword proximity
Overview
Parse 139 conversation JSON files to extract GLAM institution data using pattern-based NLP.
Goal: Extract ~2,000-5,000 TIER_4_INFERRED heritage custodian records from global GLAM research conversations.
Status: Basic extraction working, ready for full batch processing or ML enhancement.
Quick Start
1. List Available Conversations
# Count conversation files
find /Users/kempersc/Documents/claude/glam -name "*.json" -type f | wc -l
# Sample conversation names
ls -1 /Users/kempersc/Documents/claude/glam/*.json | head -20
2. Start Small - Test Extraction Pipeline
Pick 1-2 conversations to develop and test extraction logic:
Recommended Test Files:
- A Brazilian GLAM conversation (Portuguese, museums/libraries)
- A Dutch province conversation (already know Dutch institutions from CSV)
3. ✅ Extraction Pipeline (WORKING)
from pathlib import Path
from glam_extractor.parsers.conversation import ConversationParser
from glam_extractor.extractors.nlp_extractor import InstitutionExtractor
# Parse conversation
parser = ConversationParser()
conversation = parser.parse_file("2025-09-22T14-40-15-...-Brazilian_GLAM.json")
# Extract institutions
extractor = InstitutionExtractor()
result = extractor.extract_from_text(
conversation.extract_all_text(),
conversation_id=conversation.uuid
)
if result.success:
for institution in result.value:
print(f"{institution.name} ({institution.institution_type})")
print(f" Confidence: {institution.provenance.confidence_score}")
4. ✅ Batch Processing (WORKING)
# Process first 10 conversations
python scripts/batch_extract_institutions.py --limit 10
# Process all 139 conversations
python scripts/batch_extract_institutions.py
# Filter by country
python scripts/batch_extract_institutions.py --country Brazil
# Disable geocoding (faster)
python scripts/batch_extract_institutions.py --no-geocoding
# Custom output directory
python scripts/batch_extract_institutions.py --output-dir results/
Extraction Tasks (from AGENTS.md)
✅ Phase 2A: Basic Entity Extraction (COMPLETE)
-
✅ Institution Names (Pattern-Based)
- Capitalization patterns + keyword context
- Multilingual keyword detection (7 languages)
- Confidence scoring based on evidence
-
✅ Locations (Pattern Matching + GeoNames)
- Extract cities, countries from "in [City]" patterns
- GeoNames lookup for lat/lon enrichment
- ISIL prefix → country code mapping
-
✅ Identifiers (Regex Pattern Matching)
- ISIL codes:
[A-Z]{2}-[A-Za-z0-9]+✅ - Wikidata IDs:
Q[0-9]+✅ - VIAF IDs:
viaf.org/viaf/[0-9]+✅ - KvK:
[0-9]{8}✅ - URLs ✅
- ISIL codes:
-
✅ Institution Types (Keyword Classification)
- 13-type taxonomy (MUSEUM, LIBRARY, ARCHIVE, GALLERY, etc.)
- Multilingual keyword matching
- Defaults to MIXED when uncertain
⏳ Phase 2B: Advanced Extraction (NEXT PRIORITIES)
-
Relationships (Pattern Matching) - NOT STARTED
- Parent organizations
- Partnerships
- Network memberships
- Next Step: Create
src/glam_extractor/extractors/relationship_extractor.py
-
Collection Metadata (Pattern Matching) - NOT STARTED
- Collection names, types
- Item counts, time periods
- Subject areas
- Next Step: Create
src/glam_extractor/extractors/collection_extractor.py
-
Digital Platforms (Pattern Matching) - NOT STARTED
- CMS systems mentioned
- SPARQL endpoints
- Collection portals
- APIs and discovery services
-
Metadata Standards (Pattern Matching) - NOT STARTED
- Dublin Core, MARC21, EAD, etc.
- Schema.org, CIDOC-CRM
-
Organizational Change Events (Pattern Matching) - NOT STARTED
- Mergers, closures, relocations
- Name changes, reorganizations
- See AGENTS.md Task 8 for details
Implementation Strategy
Option 1: Subagent-Based (Recommended)
Pros:
- Clean separation of concerns
- Flexible (subagent chooses best NER approach)
- No heavy dependencies in main code
- Easy to experiment
Workflow:
# 1. Parse conversation
conversation = parser.parse_file(conv_path)
# 2. Launch subagent for NER
result = task_tool.invoke(
subagent_type="general",
description="Extract GLAM institutions",
prompt=f"""
Extract museum, library, and archive names from this text.
Text: {conversation.extract_all_text()}
Return JSON array with:
- name: institution name
- type: museum/library/archive/mixed
- city: location (if mentioned)
- confidence: 0.0-1.0
"""
)
# 3. Validate and convert to HeritageCustodian
institutions = json.loads(result)
custodians = [convert_to_custodian(inst, conversation) for inst in institutions]
Option 2: Direct NER (Alternative)
Pros:
- Full control over NER pipeline
- Better for debugging
Cons:
- Adds spaCy dependency to main code
- More complex error handling
Test-Driven Development Plan
Step 1: Parse Single Conversation
# Create test
touch tests/parsers/test_conversation_extraction.py
# Test: Load conversation, extract institutions (manual fixtures)
pytest tests/parsers/test_conversation_extraction.py -v
Step 2: Identifier Extraction (Regex-Based)
# Easy win: Extract ISIL codes, Wikidata IDs
# High precision, no ML needed
def extract_isil_codes(text: str) -> List[str]:
pattern = r'\b([A-Z]{2}-[A-Za-z0-9]+)\b'
return re.findall(pattern, text)
Step 3: NER via Subagent
# Launch subagent to extract institution names
# Validate results with known institutions (e.g., Rijksmuseum)
Step 4: Batch Processing
# Process all 139 conversations
# Collect statistics (institutions per country, types, etc.)
Expected Outputs
Extraction Statistics (Estimate)
Based on 139 conversations covering 60+ countries:
- Institutions extracted: 2,000-5,000 (rough estimate)
- Countries covered: 60+
- ISIL codes found: 100-300
- Wikidata links: 500-1,000
- Confidence distribution:
- High (0.8-1.0): 40%
- Medium (0.6-0.8): 35%
- Low (0.3-0.6): 25%
Provenance Metadata
All conversation-extracted records:
provenance:
data_source: CONVERSATION_NLP
data_tier: TIER_4_INFERRED
extraction_date: "2025-11-05T..."
extraction_method: "Subagent NER via Task tool"
confidence_score: 0.75
conversation_id: "conversation-uuid"
source_url: null
verified_date: null
verified_by: null
Cross-Linking Opportunities
Dutch Conversations + CSV Data
5 Dutch province conversations exist:
- Limburg (NL)
- Gelderland (NL)
- Drenthe (NL)
- Groningen (NL)
- (+ general Dutch conversations)
Validation Approach:
- Extract institutions from Dutch conversations
- Match against ISIL registry (364 records)
- Match against Dutch orgs CSV (1,351 records)
- Measure extraction accuracy using known ground truth
Expected Results:
- Precision check: % of extracted names that match CSV data
- Recall check: % of CSV institutions mentioned in conversations
- Name variation analysis: Different spellings, abbreviations

Risks and Mitigations
Risk 1: Low Extraction Quality
- Mitigation: Start with Dutch conversations (ground truth available)
- Mitigation: Use confidence scoring, flag low-confidence for review
Risk 2: Multilingual NER Challenges
- Mitigation: Let subagents choose language-specific models
- Mitigation: Focus on English + Dutch first, expand later
Risk 3: Duplicate Detection
- Mitigation: Implement fuzzy name matching
- Mitigation: Cross-reference with ISIL codes
Risk 4: Performance (139 files × NER cost)
- Mitigation: Batch processing with progress tracking
- Mitigation: Cache subagent results

Quick Commands
# Run existing conversation parser tests
pytest tests/parsers/test_conversation.py -v
# Count conversations by country (filename pattern)
ls -1 *.json | grep -o '\w\+\.json' | sort | uniq -c
# Test with a single conversation

# Process all conversations
python extract_all_conversations.py
# Validate extraction quality (Dutch conversations)
python validate_dutch_conversations.py
Immediate Next Actions
Option A: Process All Conversations (Quick Win)
# Run batch extractor on all 139 files
python scripts/batch_extract_institutions.py
# Expected output: 2,000-5,000 institutions across 60+ countries
# Output: output/institutions.json, output/institutions.csv
Option B: Improve Extraction Quality (Before Batch Run)
Priority Tasks:
- Fix location extraction - Improve country detection (most are UNKNOWN)
- Improve name extraction - Reduce variants ("Museum" vs "Museu")
- Add validation - Cross-check with Dutch CSV data
- Add Nominatim geocoding - For institutions without GeoNames match
Implementation:
- Option 1: Enhance pattern matching in
nlp_extractor.py - Option 2: Use subagent-based NER (spaCy/transformers) as originally planned
Option C: Build Advanced Extractors
Create extractors for:
relationship_extractor.py- Organizational relationshipscollection_extractor.py- Collection metadataevent_extractor.py- Organizational change events
Recommended Next Action:
Run Option A first to get baseline statistics, then assess quality and decide whether Option B enhancements are needed.
NEW: Australian Heritage Institution Extraction (Trove API)
Status: ✅ Ready to Extract
Priority: HIGH
Complexity: LOW (Authoritative API, no NLP required)
Date Added: 2025-11-18
Overview
Extract Australian heritage custodian organizations from the Trove API (National Library of Australia).
What is Trove?: Australia's national discovery service aggregating collections from libraries, archives, museums, galleries across Australia.
What is NUC?: National Union Catalogue symbols - Australia's unique identifiers for heritage institutions, equivalent to ISIL codes (format: AU-{NUC}).
Quick Start: Run Trove Extraction
1. Get Trove API Key (5 minutes)
Required: Free API key from National Library of Australia
Steps:
- Visit: https://trove.nla.gov.au/about/create-something/using-api
- Click "Sign up for an API key"
- Fill registration form (name, email, intended use: "Heritage institution research")
- Check email for API key (arrives immediately)
- Save the key securely
2. Run Extraction Script
cd /Users/kempersc/apps/glam
python scripts/extract_trove_contributors.py --api-key YOUR_TROVE_API_KEY
What happens:
- Fetches all Trove contributors (estimated 200-500 institutions)
- Retrieves full details for each (respects 200 req/min rate limit)
- Classifies institutions by GLAMORCUBESFIXPHDNT type
- Generates GHCID persistent identifiers (UUID v5, numeric)
- Exports to YAML, JSON, CSV formats
- Takes ~2-5 minutes
Output:
data/instances/
├── trove_contributors_YYYYMMDD_HHMMSS.yaml
├── trove_contributors_YYYYMMDD_HHMMSS.json
└── trove_contributors_YYYYMMDD_HHMMSS.csv
3. Validate Results
# Count institutions
wc -l data/instances/trove_contributors_*.csv
# View sample record
head -n 50 data/instances/trove_contributors_*.yaml
# Check type distribution
grep "institution_type:" data/instances/trove_contributors_*.yaml | sort | uniq -c
