Ontology / Knowledge Graph

The real cause of "AI that doesn't work" is
unstructured knowledge.

Poor LLM accuracy and ballooning costs—we trace those root causes and solve them with ontology and knowledge graphs.
Feed AI only the knowledge it needs, raising accuracy while keeping costs down.

Why don't you see results even after adopting an LLM?

Many companies feel that "costs keep rising but accuracy never comes." The cause isn't the model—it's that knowledge has never been structured.

No memory

An LLM doesn't remember the past across sessions. You have to hand over knowledge again every time, and insight never accumulates the more you use it.

Long context is expensive

Throwing in every piece of seemingly relevant knowledge inflates token billing. Costs keep piling up without translating into results.

Accuracy drops

More noise actually lowers answer accuracy and triggers hallucinations. Search misses the mark and never reaches the information you need.

Deliver only the knowledge AI needs, with nothing missing

We structure knowledge with ontology and knowledge graphs, then pass the LLM only what it truly needs at that moment. While keeping costs down, we turn your organization's knowledge into an asset AI can use correctly.

Digital Agency Hackathon Award

We won the "Legal Data Utilization Award" for structuring legislative data. With this approach we structured knowledge while reducing data volume by about 35%.

Expertise we run ourselves

We built and operate a knowledge graph platform combining Neo4j and a vector DB as our own AI development foundation. A design backed by real-world operation.

Direct support from the CEO

Our CEO—an IT consultant for listed companies, a former CTO, and a Digital Agency Digital Promotion Committee member—works alongside you directly, from strategy to implementation.

The challenges we solve

Internal knowledge search & enterprise RAG

Structure your policies, manuals, and past projects to power an in-house AI assistant that answers with supporting evidence.

Improving the accuracy of existing RAG

Turn "we deployed RAG but accuracy isn't there" around with ontology, terminology control, and hybrid search.

Laws, regulations & compliance

Structure laws, internal regulations, and contracts to enable tracking the impact of amendments and cross-referencing clauses.

Integrating product & technical information

Unify scattered master data and specifications with a knowledge graph to enable cross-cutting queries.

Frequently Asked Questions

I don't really understand ontology or knowledge graphs. Can I still consult you?

Of course. Rather than jargon, we start from "which business processes and what knowledge you want AI to use." Just tell us your current challenges first.

Can we start small?

Yes. You can start incrementally from a small-scale PoC design focused on a specific process, expanding the scope as you confirm results.

We've already deployed RAG—can we still consult you?

Yes. Cases where existing RAG isn't delivering accuracy are exactly where there's the most room to improve through ontology design and rethinking search.

How much does it cost?

The first consultation is free. We provide a quote based on project scale (hourly, from JPY 30,000/hour). See service details here.
