Complete Research Workflow

Phase 1: Extract

from scripts.citation_extractor import CitationExtractor

extractor = CitationExtractor()
research = extractor.extract_article("Subject_Name")

Phase 2: Verify

from scripts.source_verifier import SourceVerifier

verifier = SourceVerifier()

# Verify all citations (DOI, PMID, URL checks)
citation_results = verifier.verify_citations(research['citations'])

# Detect inconsistencies
inconsistencies = verifier.detect_inconsistencies(research)

# Extract Wikipedia uncertainty flags ({{citation needed}}, etc.)
flags = verifier.extract_uncertainty_flags(wikitext)

# Generate verification report
report = verifier.generate_verification_report(
    research, citation_results, inconsistencies, flags
)

Phase 3: Enrich

from scripts.entity_extractor import EntityExtractor

entity_extractor = EntityExtractor()

# Extract people, organizations, publications mentioned
entities = entity_extractor.extract_entities(research)

# Map relationships (collaborators, employers, etc.)
relationships = entity_extractor.extract_relationships(
    research, entities, "Subject Name"
)

# Build chronological timeline
timeline = entity_extractor.build_timeline(research)

# Generate knowledge graph
graph = entity_extractor.generate_knowledge_graph(
    "Subject Name", entities, relationships, timeline
)

Phase 4: Output

from scripts.research_collector import ResearchCollector

collector = ResearchCollector()
collector.save_research({
    **research,
    'verification': report,
    'knowledge_graph': graph
}, "output.json")

Verification Features

Citation Validation

verifier = SourceVerifier()
result = verifier.verify_citations(citations)

# Each citation gets:
# - status: 'verified', 'accessible', 'dead_link', 'archived'
# - doi_valid: True/False (checked against doi.org)
# - pmid_valid: True/False (checked against PubMed)
# - archive_url: Wayback Machine fallback if dead

Uncertainty Detection

Automatically flags Wikipedia uncertainty templates:

• {{citation needed}} - Unsourced claim
• {{disputed}} - Contested information
• {{original research}} - May lack sources
• {{outdated}} - Information may be stale
• {{who}} / {{when}} - Vague attribution

Inconsistency Detection

Cross-checks claims within the research:

• Date conflicts (PhD year differs between sections)
• Name variations
• Contradictory facts

Entity & Relationship Extraction

Entity Types

Type	Examples
person	Collaborators, mentors, colleagues
organization	Universities, companies, institutes
publication_venue	Journals, conferences
concept	Research fields, methods

Relationship Types

Type	Meaning
collaborator	Research collaboration
employment	Work affiliation
education	Degree/training
publication	Published in venue
award_from	Received award from

Timeline Construction

Automatically extracts chronological events:

{
  "timeline": [
    {"date": "2005", "type": "education", "description": "BSc from University of Manchester"},
    {"date": "2010", "type": "education", "description": "PhD from Humboldt University"},
    {"date": "2011", "type": "publication", "description": "Published protein structure paper"},
    {"date": "2016", "type": "award", "description": "Received Overton Prize"}
  ]
}

Quality Metrics

Source Quality (Admiralty Code)

Rating	Score	Meaning
A	0.80+	Completely reliable - most citations verified
B	0.60-0.79	Usually reliable
C	0.40-0.59	Fairly reliable
D	0.20-0.39	Not usually reliable
E	<0.20	Unreliable

Confidence Scoring

Method: Additive heuristic based on citation metadata presence.

Each claim's confidence is the average score of its supporting citations, calculated as:

Base score:                 0.50
+ DOI present:             +0.20  (indicates peer-reviewed)
+ PMID present:            +0.15  (indexed in PubMed)
+ ISBN present:            +0.10  (published book)
+ URL present:             +0.05  (verifiable link)
+ Author info present:     +0.10  (attributable)
+ Publication venue named: +0.05  (traceable)
─────────────────────────────────
Maximum possible:           1.00

Typical scores:

Citation Type	Score
Journal article (DOI + PMID + author)	0.95-1.0
Journal article (DOI + author)	0.85
Book (ISBN + author)	0.75
Webpage (URL + author)	0.65
Bare URL only	0.55
Citation not found	0.30

Limitations of this approach:

• Does NOT verify that the source actually supports the claim
• Does NOT perform semantic analysis of source content
• Assumes DOI ≈ peer-reviewed (not always true for preprints)
• No weighting by journal reputation or citation count

For higher-confidence verification: Use source_verifier.py to validate DOIs/PMIDs exist, then manually verify claim-source alignment for critical facts.

Best Practices

1. Always verify - Run source_verifier on all research
2. Check uncertainty flags - Wikipedia often marks weak areas
3. Build timelines - Chronology reveals inconsistencies
4. Extract relationships - Context matters for understanding
5. Save revision_id - Wikipedia changes; enable reproducibility
6. Use DOIs - Most reliable citation identifiers
7. Check archives - Dead links often have Wayback copies
