kempersc 626bd3a095 refactor(schemas): apply naming conventions to 261 class files 
- Apply Rule 39: RiC-O style hasOrHad*/isOrWas* for temporal slots
- Apply Rule 43: Singular noun convention (keywords → keyword)
- Update slot references to match renamed slot files
- Maintain schema integrity across all class definitions

description: "A single verifiable claim extracted from a web page.\n\n**CORE PRINCIPLE:\
\ XPATH OR REMOVE**\n\nEvery claim extracted from a webpage MUST have:\n1. `xpath`\
\ - pointing to exact element in archived HTML\n2. `html_file` - path to the\
\ archived HTML (Playwright-rendered, NOT WARC)\n3. `xpath_match_score` - quality\
\ of the match\n\nClaims without these fields are FABRICATED and must be REMOVED.\n\
\n**ARCHIVE FORMAT: PLAYWRIGHT-RENDERED HTML**\n\nWe use Playwright (headless\
\ browser) to:\n1. Navigate to the target URL\n2. Wait for JavaScript to fully\
\ render\n3. Save the complete DOM as an HTML file\n\nThis differs from WARC\
\ archives which capture raw HTTP responses.\nPlaywright rendering captures\
\ the final DOM state including:\n- JavaScript-rendered content\n- Dynamically\
\ loaded elements\n- Client-side state\n\n**WHY NOT CONFIDENCE SCORES?**\n\n\
Confidence scores like `0.95` are MEANINGLESS because:\n- There is NO methodology\
\ defining what these numbers mean\n- They cannot be verified or reproduced\n\
- They give false impression of rigor\n- They mask the fact that claims may\
\ be fabricated\n\nInstead, we use VERIFIABLE provenance:\n- XPath points to\
\ exact location\n- Archived HTML can be inspected\n- Match score is computed,\
\ not estimated\n\n**EXTRACTION PIPELINE (4 Stages)**\n\nFollowing the GLAM-NER\
\ Unified Entity Annotation Convention v1.7.0:\n\n1. **Entity Recognition**\
\ (Stage 1)\n - Detect named entities in text\n - Classify by hypernym type\
\ (AGT, GRP, TOP, TMP, etc.)\n - Methods: spaCy NER, transformer models, regex\
\ patterns\n\n2. **Layout Analysis** (Stage 2)\n - Analyze document structure\
\ (headers, paragraphs, tables)\n - Assign DOC hypernym types (DOC.HDR, DOC.PAR,\
\ DOC.TBL)\n - Generate XPath provenance for each claim location\n\n3. **Entity\
\ Resolution** (Stage 3)\n - Disambiguate entity mentions\n - Merge coreferences\
\ and name variants\n - Produce canonical entity clusters\n\n4. **Entity Linking**\
\ (Stage 4)\n - Link resolved entities to knowledge bases\n - Connect to\
\ Wikidata, ISIL, GeoNames, etc.\n - Assign link confidence scores\n\n**WORKFLOW**:\n\
\n1. Archive website using Playwright:\n `python scripts/fetch_website_playwright.py\
\ <entry_number> <url>`\n \n This saves: web/{entry_number}/{domain}/rendered.html\n\
\n2. Add XPath provenance to claims:\n `python scripts/add_xpath_provenance.py`\n\
\n3. Script REMOVES claims that cannot be verified\n (stores in `removed_unverified_claims`\
\ for audit)\n\n**EXAMPLES**:\n\nCORRECT (Verifiable):\n```yaml\n- claim_type:\
\ full_name\n claim_value: Historische Vereniging Nijeveen\n source_url: https://historischeverenigingnijeveen.nl/\n\
\ retrieved_on: \"2025-11-29T12:28:00Z\"\n xpath: /html[1]/body[1]/div[6]/div[1]/h1[1]\n\
\ html_file: web/0021/historischeverenigingnijeveen.nl/rendered.html\n xpath_match_score:\
\ 1.0\n pipeline_stage: layout_analysis\n```\n\nWRONG (Fabricated - Must Be\
\ Removed):\n```yaml\n- claim_type: full_name\n claim_value: Historische Vereniging\
\ Nijeveen\n confidence: 0.95 # ← NO! This is meaningless without XPath\n\
```\n"

slot_usage:
claim_type:
required: true
description: |
Type of claim. See ClaimTypeEnum for allowed values.
Each claim type has expected source locations:
- full_name: <title>, <h1>, logo, og:title
- description: <meta name="description">, about section
- email: <a href="mailto:...">, contact page
- phone: <a href="tel:...">, contact page
- address: footer, contact page, JSON-LD
claim_value:
required: true
description: |
The extracted value. Must appear at the XPath location.
source_url:
required: true
description: |
URL of the web page this claim was extracted from.
Required for all claims - enables verification of provenance.
retrieved_on:
required: true
description: |
Timestamp when the web page was archived using Playwright.
ISO 8601 format with timezone (UTC preferred).
xpath:
required: true
description: |
XPath to element containing claim_value.
**THIS IS THE CRITICAL PROVENANCE FIELD.**
Without an XPath, a claim is unverifiable and must be removed.
Format: Standard XPath 1.0 expression
Example: /html[1]/body[1]/div[6]/div[1]/table[3]/tbody[1]/tr[1]/td[1]/p[6]
html_file:
required: true
description: |
Path to archived HTML file (relative to entry file).
Archive format: Playwright-rendered HTML (NOT WARC).
Playwright captures the fully rendered DOM after JavaScript execution.
Standard structure:
web/{entry_number}/{domain}/rendered.html
Example: web/0021/historischeverenigingnijeveen.nl/rendered.html
xpath_match_score:
required: true
description: |
Match quality between claim_value and text at XPath.
This is COMPUTED, not estimated:
- 1.0: claim_value == element_text (exact)
- <1.0: len(claim_value) / len(element_text) for substrings
Claims with score < 0.3 should be flagged for review.
pipeline_stage:
description: |
The extraction pipeline stage that produced this claim.
Most WebClaims are produced during:
- layout_analysis (Stage 2): When XPath locations are identified
- entity_linking (Stage 4): When claims link to knowledge bases

comments:
- WebClaim requires XPath provenance - claims without it are fabricated
- Match score is COMPUTED from actual text comparison, not estimated
- Archived HTML files are Playwright-rendered (NOT WARC format)
- Use scripts/fetch_website_playwright.py to archive websites
- Use scripts/add_xpath_provenance.py to add XPath to existing claims
- 'Follows 4-stage GLAM-NER pipeline: recognition → layout → resolution → linking'
