TruGround™
Frontier AI demands domain authority that human feedback can’t meet at scale.
TruGround delivers semantic feedback from the worlds leading text books and journals.
HF Optimizes Human-Perceived Utility
Human feedback provides a reward signal for outputs that feel helpful, safe, and fluent. RLHF aligns models with human preferences—a critical foundation for alignment.
But Cannot Scale Domain Expertise
Human experts cannot label millions of examples at frontier scale. Crowdsourced annotators cannot evaluate deep domain correctness across medicine, law, or science.
No Structured Knowledge Validation
HF optimizes tone and preference—not structural knowledge integrity. It cannot provide deterministic admissibility checking or ontology-level constraint enforcement.
Labor Cost Prevents Scalability
The economics of human annotation prevent HF from functioning as a scalable knowledge-accuracy signal. High-resolution domain validation is labor-bounded.
The Knowledge-Accuracy Signal
TruGround does not replace RLHF. It augments it by adding a scalable knowledge-accuracy signal.
Two Complementary Reward Dimensions
Human feedback signals align models with user preferences, safety norms, and conversational quality.
Semantic feedback signals ground models in structured domain authority, factual constraints, and provenance validation.
TruGround does not create opinion signals. It creates deterministic semantic constraint signals.
From Textbook Knowledge to Machine-Readable Constraints
TruGround transforms authoritative domain knowledge into structured semantic infrastructure that can generate reward signals, evaluation rubrics, and grounding contexts at scale.
Machine-Readable Taxonomies
8.1M concept nodes organized hierarchically across every major domain
Structured Ontologies
6B semantic triples encoding typed relationships and constraints
Constraint Systems
Provenance-aware knowledge graphs with deterministic validation logic
Reward Functions
Generate evaluation rubrics and preference pairs grounded in domain authority
From Source Text to Structured Grounding Context
Every authoritative source becomes a knowledge-accuracy signal. Our pipeline extracts verifiable semantic triples, attaches them to domain taxonomies, and makes them available for model grounding.
Parse Authoritative Sources
Extract assertions from textbooks, documentation, and expert-authored content
Build Semantic Triples
Subject → Predicate → Object relationships with provenance
Attach to Taxonomies
Link assertions to typed concept hierarchies and constraint systems
Generate Training Signals
Produce reward functions, rubrics, and grounding contexts for RL
The result: A scalable knowledge-accuracy signal that complements human feedback. RLHF + RLSF = alignment with both human preferences and structural reality.
How TruGround Works
From domain knowledge to deployed training signal — a rigorous, four-phase pipeline.
Domain Mapping
Our subject-matter experts identify the taxonomies in the TrueGround catalog that cover your target training domain.
Semantic Encoding
The domain taxonomies are exported as machine-readable taxonomies preserving the hierarchical ontologies with typed relationships, constraints, and provenance metadata.
Signal Generation
Taxonomies are transformed into training-compatible signals: reward functions, preference pairs, evaluation rubrics, and structured grounding contexts.
Integration & Evaluation
Signals integrate into existing fine-tuning and evaluation pipelines. Continuous feedback loops keep taxonomies current as domains evolve.
Taxonomy Catalog
Structured Domain Knowledge
A growing catalog of expert-validated semantic taxonomies across high-stakes verticals where accuracy is non-negotiable.
Millions of concept nodes across mission-critical domains. Every taxonomy backed by authoritative sources, structured for deterministic validation.

What Makes This Different
TruGround isn’t a dataset, a benchmark, or a labeling service. It’s semantic infrastructure for grounded AI.
Structural, Not Statistical
Our taxonomies encode the logical structure of a domain — hierarchies, constraints, and typed relationships — not just statistical co-occurrence patterns from corpora.
Expert-Validated
Every taxonomy is built by credentialed domain experts. We embed provenance and confidence metadata at every node for full auditability.
Trillion-Token Scale
Operating at Common Crawl magnitude, TruGround delivers semantic signals at a scale human annotation platforms physically cannot match. Domain authority at frontier model scale.
Continuously Updated
Domains evolve — regulations change, new research emerges, standards shift. Our taxonomies are living artifacts with versioned updates and change provenance.
Where Grounded Truth Matters
When getting it right isn’t optional — TruGround provides the semantic substrate that makes AI trustworthy.
Fine-Tuning with Domain Authority
Replace generic instruction data with semantically structured domain knowledge. Guide model behavior toward factually grounded outputs during supervised and reinforcement training.
Evaluation Beyond Vibes
Build domain-specific evaluation benchmarks grounded in expert-validated taxonomies. Measure factual accuracy, not just fluency or user preference.
RAG Grounding Layer
Enhance retrieval-augmented generation with structured knowledge. Taxonomies provide semantic scaffolding that improves retrieval relevance and generation accuracy.
Enterprise AI Governance
Establish verifiable ground truth for AI outputs in regulated industries. Provide auditors and compliance teams with traceable, authoritative reference structures.
Ground Your AI in Truth
Whether you’re building frontier models or deploying AI in regulated environments — TruGround gives your systems the authoritative knowledge substrate they need.
