FAQPage Schema
How do I verify a claim against available evidence to determine its reliability?

To verify a claim against available evidence, you provide the assertion, optional sources, and a required strength threshold. The system evaluates the inputs and outputs a structured object detailing grounded status, supporting evidence, contradictions, and confidence.

What is evidence provenance and when do I need it for auditing claims?

Evidence provenance anchors assertions to authoritative sources, enabling audits and reducing hallucinations. You need provenance when verifying facts in reports, validating QA results, or ensuring compliance by tracking the origin and reliability of claims.

How do I identify contradictions and gaps when grounding claims to evidence?

Identifying contradictions and gaps when grounding claims involves checking the provided claim against available sources. The system outputs a structured object detailing specific contradictions, missing evidence gaps, and anchors for auditability.

Can I set a required strength threshold to validate claims with uncertainty?

Yes, you can set a required strength threshold to validate claims with uncertainty. Providing a strength threshold is required, and the system uses it to output a grounded status and confidence level based on the supporting evidence.

Does grounding claims with provenance work for compliance and QA validation?

Grounding claims with provenance works for compliance and QA validation by anchoring assertions to authoritative evidence. Use cases include verifying facts in reports, validating QA results, and ensuring compliance through structured audit trails.

What's the best way to anchor assertions to authoritative sources for audit trails?

The best way to anchor assertions to authoritative sources for audit trails is to submit the claim with optional sources and a strength threshold. This returns a structured object with supporting evidence, contradictions, gaps, and anchors for auditability.
