Overview

The core differentiator of a journalism-investigation KB over raw data tools like Aleph: structured claim management with evidence chains and source reliability tracking. Every factual assertion links to source documents, each rated for reliability. Claims have a lifecycle from unverified to corroborated or disputed.

This is what makes an investigation publishable — the evidence chain from claim to source.

Subtasks

1. Claim lifecycle — claim entry type with status transitions, corroboration tracking, dispute resolution 2. Evidence chain tracking — link claims to evidence to source documents, visualize chains 3. Source reliability framework — reliability ratings, source tier system, cross-source consistency checks 4. Claim-to-edge promotion — convert corroborated claims about relationships into structural edge-entities

Success Criteria

  • Claims track from unverified → corroborated with linked evidence
  • Evidence chains are traversable: claim → evidence → source_document
  • Source reliability informs claim confidence automatically
  • QA flags orphan claims (no evidence) and unsourced evidence
