SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This solution streamlines journalism-investigation knowledge management by validating claims against verifiable evidence, reducing rumor-driven errors.

Core Features & Use Cases

  • Evidence-driven verification: automatically identify unverified claims, gather corroborating or contradicting evidence, and update confidence levels with auditable traces.
  • Traceable chain creation: enforce an evidence-first workflow, linking claims to evidence and sources for full provenance.
  • Output & reporting: generate a structured verification report summarizing findings, sources, and uncertainties for editorial review.

Quick Start

From a journalism KB, identify a claim and run the fact-checker to produce a verification report with linked evidence.

FAQPage Schema
How do I verify claims in an investigative journalism knowledge base?

To verify claims in an investigative journalism knowledge base, you can run an automated fact-checker that identifies unverified assertions, gathers corroborating or contradicting evidence, and generates a structured verification report with linked sources.

What is evidence-driven fact-checking and how does it work?

Evidence-driven fact-checking is a process that evaluates unverified assertions by enforcing an evidence-first rule, automatically linking claims to gathered sources to update confidence levels with an auditable provenance chain.

How do I generate a verification report with an auditable evidence chain?

Generating an auditable verification report involves evaluating claims against gathered evidence, updating claim statuses and confidence levels, and outputting a comprehensive summary with reasoning, sources, and uncertainties for editorial review.

Can I use fact-checking tools to manage evidence provenance for editorial review?

Yes, you can use fact-checking tools to manage evidence provenance by enforcing an evidence-first workflow that links claims to specific sources, creating full traceability for editorial review and reducing rumor-driven errors.

Does the fact-checker support MCP tools for claim and evidence management?

Yes, the fact-checker supports MCP tools specifically for claim and evidence management, allowing you to identify unverified claims and update their status with traceable evidence across investigative workflows.

What are the limitations of automated claim verification in journalism investigation?

Automated claim verification limitations include handling uncertainties in gathered evidence, requiring a structured journalism knowledge base to function, and outputting confidence levels rather than absolute truths to support editorial review.
