Government & Public Sector

One citizen. Three identities.

Two agencies. Zero visibility.

Each agency has its own system, its own identifiers, and its own view of the person in front of them. The same individual can claim benefits from two programs under three identities, and no one agency will ever see the full picture. LangOptima connects them into a single knowledge graph, with governance built in.

The approach behind EUR-Lex, where the EU's Publications Office stores every treaty, regulation, and judgment as RDF, so law and policy connect across languages and systems.

The Status Quo

Every agency. Its own system. No cross-reference.

The siloed data that protects citizen privacy also shields duplicate identities, synthetic personas, and cross-program fraud. The answer is not less privacy. It is better connection, under governance.

🏛️

Agency-local identity

Each agency assigns its own identifiers. The same individual is a different record in every system. Without entity resolution, nothing is ever connected.

📄

No cross-referencing

Cross-agency checks today are manual, episodic, and low-signal. Most duplicate identities and synthetic personas never trigger a review.

⚠️

Fraud rings invisible by design

Organized benefit fraud relies on agency-local data. Shared addresses, shared bank accounts, and shared digital identifiers sit in the gap between systems that no one is connecting.

The Knowledge Graph

Entity resolution at the semantic layer. Privacy by design.

LangOptima models people, organizations, addresses, programs, and transactions as connected entities in a governed knowledge graph. Agency data remains owned by each agency. The graph is the layer where entity resolution happens, with role-based access control, full audit logging, and minimum-necessary exposure by default.

Modern AI can structure a great deal on its own. Where it stops is the meaning specific to your organization: the concepts, rules, and relationships that make your business yours, and where its real value lives. We structure that layer with you on open, world-standard semantics, not a proprietary schema, so the graph reflects how you operate and stays yours: no vendor lock-in, portable to whatever you run next.

You don't have to boil the ocean. Start with a single business context and prove it there. Once that foundation is laid properly, the same connected data tends to open opportunities in other departments, so the next team builds on the work already done rather than starting from zero.

Pillar 01

Connected Data

Cross-agency data unified at the semantic layer without moving or copying it. Role-based access control and audit logging built in from day one.

Pillar 02

Hidden Insights

Surface the same individual under multiple identities, detect benefit claims in two programs simultaneously, and uncover networks connected through shared addresses or bank accounts.

Pillar 03

Faster Decisions

Investigations move from months to weeks. Referrals come with complete evidence chains, ready for prosecutorial review.

Pillar 04

Amplified Teams

Fraud investigators, program integrity teams, and cross-agency task forces stop rebuilding context on every case. The graph becomes the shared working memory of the investigation.

Government Agency

$12M in duplicate benefit payments identified

A government agency identified $12M in duplicate benefit payments within the first pilot by modeling people, addresses, programs, and transactions as a connected knowledge graph. Individuals operating under three identities across agencies were surfaced within the first month.

Privacy by Design

Connected insight, not copied data

Agency data never leaves agency control. The knowledge graph federates access at the semantic layer with role-based governance, audit trails, and minimum-necessary exposure: the opposite of a data lake dumping ground.

How It Works

The way this works is simple. Three parts.

However complex the data landscape underneath, the engagement itself stays simple.

Step 01

Connect

Pick one decision that matters, say resolving one person across agency systems and identifiers. We build the knowledge graph over the case, benefits, and registry systems you already run, with governance built in. Nothing is replaced. Your teams keep working where they work today.

Step 02

Ground

Your team's questions, reports, and AI run on that connected layer. Answers come in seconds, accurate and traceable, with citations back to the source so you can check them yourself.

Step 03

Prove

A working result in a scoped 8–12 week paid pilot, measured against success criteria you set. If it proves value, you expand from there. If it doesn't, it doesn't scale.

Program integrity

starts with entity resolution.

Start with a 30-minute conversation. Tell us about the program, the duplicate-identity problem, or the cross-agency referral that is hardest to complete today, and we’ll show you how a governed knowledge graph would approach it.
