Discovery & Research for Public Sector

Discovery and Research workflows ask the system to find the right documents and synthesize what they say, with the citations being more important than the synthesis. Citorum's hybrid retrieval pipeline combines dense vector similarity over the embeddings of every document chunk, full-text search via Postgres' built-in indexing, and metadata filtering against tags, dates, jurisdictions, document types, and access-control attributes. Results are scored, deduplicated, and rank-fused into a context window.

The model produces a research summary; the audit log captures every document that contributed, every citation rendered, and the faithfulness score on every claim. The reviewing analyst — paralegal, compliance officer, claims coder, briefer — clicks through to source spans rather than relying on the summary verbatim. The pattern works because the citations are first-class output, not a footnote.

Public-sector deployments — federal civilian, federal defense, state, and local — share a common set of constraints: data residency in the appropriate cloud or on-premises facility; an audit format that the Office of Inspector General or Government Accountability Office can consume; identity in the agency's Identity Provider with role-based access control gating document scope; and a controls posture that maps cleanly to the National Institute of Standards and Technology (NIST) 800-53 control families.

Citorum supports the deployment topologies these constraints demand: on-premises in the agency's data center, in a customer-owned Virtual Private Cloud (VPC) on Federal Risk and Authorization Management Program (FedRAMP)-authorized hyperscaler regions, or as a Citorum-managed dedicated tenant in a FedRAMP-aligned account. Common workflows include records research across agency document repositories, citizen-services policy Q&A for caseworker and call-center staff, briefing-note drafting for program leadership, and program knowledge Q&A across the regulations and procedures that govern the work.
