Low 60 20.1% Fallback to general classes (default: crm:E27_Site + schema:Place)

Ontology Coverage

Ontology Entries Using Description
Schema.org (schema:) 521 Web semantics, broad coverage
CIDOC-CRM (crm:) 318 Cultural heritage domain standard ✅
DBpedia (dbo:) 200 Linked data from Wikipedia
GeoSPARQL (geo:) 298 Spatial features (all entries)
W3C Org (org:) 2 Organizational structures

Key Achievement: 100% CIDOC-CRM coverage (all 298 entries have at least one crm: class)

Example Mappings

Example 1: MANSION (High-Quality Mapping)

MANSION:
  title: mansion
  description: very large and imposing dwelling house
  meaning: wd:Q1802963
  
  exact_mappings:
    - crm:E22_Human-Made_Object  # CIDOC-CRM: Physical building
    - dbo:Building               # DBpedia: Building class
  
  close_mappings:
    - schema:LandmarksOrHistoricalBuildings  # Schema.org: Heritage building
    - schema:Place                            # Schema.org: Generic place
  
  related_mappings:
    - geo:Feature  # GeoSPARQL: Geographic feature
  
  annotations:
    wikidata_id: Q1802963
    cidoc_crm_class: crm:E22_Human-Made_Object
    dbpedia_class: dbo:Building
    schema_org_class: schema:LandmarksOrHistoricalBuildings
    mapping_confidence: medium
    mapping_date: 2025-11-22

Rationale: Mansion is a physical building (E22), heritage landmark (Schema.org), and general building (DBpedia).

Example 2: PARISH_CHURCH (Religious Building)

PARISH_CHURCH:
  title: parish church
  meaning: wd:Q317557
  
  exact_mappings:
    - crm:E22_Human-Made_Object  # Physical building
    - dbo:Building               # Building class
  
  close_mappings:
    - schema:Church              # Schema.org: Specific church type
    - schema:PlaceOfWorship      # Schema.org: Religious function
    - schema:LandmarksOrHistoricalBuildings
    - schema:Place
  
  related_mappings:
    - geo:Feature
  
  annotations:
    mapping_confidence: medium

Rationale: Churches are buildings with religious function, heritage value.

Example 3: MUSEUM (Direct DBpedia Mapping)

MUSEUM:
  title: museum
  meaning: wd:Q33506
  
  exact_mappings:
    - crm:E22_Human-Made_Object  # CIDOC-CRM fallback
    - dbo:Museum                 # DBpedia: Direct equivalence
    - schema:Museum              # Schema.org: Museum class
  
  close_mappings:
    - schema:Place
  
  related_mappings:
    - geo:Feature
  
  annotations:
    cidoc_crm_class: crm:E22_Human-Made_Object
    dbpedia_class: dbo:Museum
    schema_org_class: schema:Museum
    mapping_confidence: high  # ← Direct DBpedia mapping!

Rationale: Museum has direct dbo:Museum ↔ wd:Q33506 equivalence in DBpedia.

Example 4: HERITAGE_SITE (Site-Based Mapping)

HERITAGE_SITE:
  title: heritage site
  meaning: wd:Q???
  
  exact_mappings:
    - crm:E27_Site  # CIDOC-CRM: Physical site
  
  close_mappings:
    - dbo:HistoricPlace                    # DBpedia: Historic place
    - schema:LandmarksOrHistoricalBuildings
    - schema:Place
  
  related_mappings:
    - geo:Feature
  
  annotations:
    cidoc_crm_class: crm:E27_Site
    schema_org_class: schema:LandmarksOrHistoricalBuildings
    mapping_confidence: medium

Rationale: Heritage sites map to E27_Site (CIDOC-CRM site class).

Mapping Rules Applied

Rule 1: DBpedia-Wikidata Direct Equivalence (High Confidence)

Source: dbpedia_wikidata_mappings.ttl (335 mappings loaded)

if q_number in dbpedia_mappings:
    exact_mappings.add(dbpedia_mappings[q_number])  # e.g., dbo:Museum
    mapping_confidence = 'high'

Examples:

  • wd:Q33506 → dbo:Museum
  • wd:Q41176 → dbo:Building
  • wd:Q7075 → dbo:Library

Coverage: 13 entries (4.4%)

Rule 2: Hypernym-Based Semantic Rules (Medium Confidence)

15 hypernym categories with ontology mapping rules:

Hypernym Exact Mappings Close Mappings
building crm:E22_Human-Made_Object, dbo:Building schema:LandmarksOrHistoricalBuildings
heritage site crm:E27_Site dbo:HistoricPlace, schema:LandmarksOrHistoricalBuildings
protected area crm:E27_Site schema:Park, geo:Feature
structure crm:E25_Human-Made_Feature crm:E26_Physical_Feature
museum schema:Museum, dbo:Museum crm:E22_Human-Made_Object
park crm:E27_Site, schema:Park geo:Feature
infrastructure crm:E25_Human-Made_Feature schema:Place
grave crm:E27_Site schema:Place
monument crm:E25_Human-Made_Feature schema:LandmarksOrHistoricalBuildings
settlement crm:E27_Site schema:Place
station crm:E22_Human-Made_Object schema:Place
organisation org:Organization dbo:Organisation, schema:Organization
object crm:E22_Human-Made_Object schema:Thing
space crm:E53_Place schema:Place
memory space crm:E53_Place schema:Place

Coverage: 225 entries (75.5%)

Rule 3: Default Fallback (Low Confidence)

When no DBpedia mapping or hypernym rule applies:

exact_mappings.add('crm:E27_Site')       # Every feature is at least a site
close_mappings.add('schema:Place')        # Every feature is a place
related_mappings.add('geo:Feature')       # Every feature is geographic

Coverage: 60 entries (20.1%)

Data Sources:

  1. DBpedia mappings: dbpedia_wikidata_mappings.ttl (335 mappings)
  2. Hypernym rules: 15 predefined hypernym → ontology class mappings
  3. Default fallbacks: crm:E27_Site + schema:Place + geo:Feature

Output: Updated FeatureTypeEnum.yaml (224 KB)

Phase 2: Manual Review (Optional, Not Yet Done)

Recommended for: 60 entries with mapping_confidence: low

Process:

  1. Review Wikidata descriptions for each entry
  2. Search ontology files for better semantic matches
  3. Update mappings with more specific classes
  4. Document rationale in mapping_note field

Estimated time: 3-4 hours

Benefits of Ontology Mapping

1. Semantic Interoperability

Heritage data can now be queried using formal ontology classes:

# SPARQL query using CIDOC-CRM
SELECT ?feature WHERE {
  ?feature rdf:type crm:E22_Human-Made_Object .
  ?feature wd:featureType ?type .
}

2. Linked Data Integration

DBpedia mappings enable cross-dataset linking:

# RDF triple using DBpedia class
<https://nde.nl/ontology/hc/feature/mansion-001>
    rdf:type dbo:Building ;
    wd:featureType wd:Q1802963 .

3. Web Discoverability

Schema.org mappings improve SEO and web indexing:

{
  "@context": "https://schema.org",
  "@type": "LandmarksOrHistoricalBuildings",
  "name": "Historic Mansion",
  "featureType": "mansion"
}

4. Cultural Heritage Standards Compliance

CIDOC-CRM mappings ensure compatibility with museum/archive standards:

✅ Compatible with: Europeana, DPLA, Cultural Heritage Linked Open Data
✅ Follows: CIDOC-CRM v7.1.3 standard
✅ Integrates with: Museum collection management systems

Next Steps (Optional Enhancements)

Phase 2: Manual Review

Priority: 60 entries with mapping_confidence: low

Process:

  1. Review Wikidata descriptions
  2. Search /data/ontology/ files for better matches
  3. Update exact_mappings with more specific classes
  4. Add mapping_note explaining rationale

Examples:

ESOTERIC_FEATURE:
  exact_mappings:
    - crm:E27_Site  # Improved from default
    - dbo:SpecificClass  # Found in manual review
  mapping_note: >-
    Manual review found better mapping to dbo:SpecificClass
    based on Wikidata description analysis.    
  mapping_confidence: medium  # Upgraded from low

Phase 3: Additional Ontologies

Consider mapping to:

  • Getty AAT: Art & Architecture Thesaurus (architectural styles)
  • RiC-O: Records in Contexts (archival description)
  • INSPIRE: EU spatial data infrastructure
  • UNESCO Thesaurus: Cultural heritage terminology

Phase 4: Validation Against Real Data

Test mappings with actual heritage institution records:

  1. Load example FeaturePlace instances
  2. Validate ontology class assignments
  3. Check for mapping conflicts
  4. Refine rules based on real-world data

## Extracting FeaturePlace with Ontology Awareness

When extracting physical feature types from conversations:

1. **Identify feature type**: "mansion", "church", "monument"
2. **Look up in FeatureTypeEnum**: Check for matching Wikidata Q-number
3. **Use ontology mappings**: Automatically inherit CIDOC-CRM, DBpedia, Schema.org classes
4. **Create FeaturePlace instance**:
   ```yaml
   FeaturePlace:
     feature_type: MANSION
     # Inherited ontology classes:
     # - crm:E22_Human-Made_Object
     # - dbo:Building
     # - schema:LandmarksOrHistoricalBuildings
  1. Link to CustodianPlace: Connect via classifies_place relationship
