7. Fact-checking dashboard for transparency

User Requirements:

• Intuitive interface for easy navigation and content creation
• Clear indicators of content verification status
• Ability to challenge or appeal fact-check results
• Privacy controls and data protection measures
• Cross-platform accessibility (web and mobile)

User Flows

1. Content Posting and Verification:

   • User creates a new post
   • System automatically scans content for factual claims
   • AI fact-checking engine verifies claims against trusted sources
   • Post is published with a verification status indicator
   • Users can view detailed fact-check results

2. Browsing Verified Content:

   • User logs in and accesses their personalized news feed
   • Feed displays posts with clear verification status indicators
   • User can filter content based on verification status
   • Clicking on a post shows detailed fact-check information

3. Challenging Fact-Check Results:

   • User disagrees with a fact-check result
   • User submits an appeal with additional evidence
   • Human moderators review the appeal
   • Fact-check status is updated if necessary

Design Rationale

The design decisions for this project prioritize scalability, reliability, and user trust. React and Node.js were chosen for their performance and large ecosystems. PostgreSQL provides robust data integrity for user and content information. The automated fact-checking feature is central to the platform's value proposition, differentiating it from existing social media sites. The modular architecture allows for easy updates and feature additions. The deployment strategy focuses on high availability and quick scaling to handle potential viral growth. Overall, the design aims to create a trustworthy social platform that can grow with user demand while maintaining content integrity.
