About

EU Fact Force is a collaborative platform developed by EUPHA (European Public Health Association) with support from Data For Good volunteers. The platform empowers public health professionals to counter health misinformation by:

• Connecting scientific evidence with disinformation narratives
• Visualizing knowledge graphs of research articles, claims, and concepts
• Tracking disinformation trends through integration with PGP (The Public Good Projects) monitoring data
• Enabling rapid response with validated counter-narratives

Use Case

Marie, a health communicator at a national public health association, sees a viral post claiming "vaccines cause autism." She needs to respond quickly with solid evidence.

She searches "vaccines autism" on EU Fact Force and immediately sees:

• An interactive graph showing 15+ peer-reviewed articles that refute this claim
• The scientific consensus: "Refuted with high confidence"
• Current disinformation trends: 1,200 mentions this week, peak in France/Belgium
• Key evidence to cite in her response

Time to find relevant evidence: <30 seconds

Key Features

V0 (Minimum Viable Product - Target: April 2026)

• Semantic Search (FR/EN): Find relevant scientific articles even without exact keyword matches
• Interactive Knowledge Graph: Explore connections between articles, claims, and narratives
• Disinformation Trends: Visualize PGP monitoring data (volume, geography, examples)
• Researcher Upload: Members can upload scientific articles with auto-extracted metadata
• Multilingual: Interface and search in French and English
• Access Control: Authentication system for EUPHA members

Scope V0

• 3 priority narratives (e.g., vaccines-autism, moderate alcohol benefits, COVID misinformation)
• 100-150 scientific articles from EJPH, WHO, ECDC, and other trusted sources
• 20-30 claims per narrative (confirmed/refuted/nuanced)
• Integration with PGP data (weekly batch updates)
