OntoMetric: Ontology-Guided ESG Knowledge Graph Construction

Unstructured ESG documents present significant challenges for compliance, interpretation, and auditability. OntoMetric introduces a novel ontology-guided framework that transforms these complex regulatory texts into validated, AI-ready knowledge graphs, significantly improving accuracy and efficiency over traditional LLM methods.

Executive Impact: Transforming ESG Compliance

OntoMetric dramatically enhances the reliability and cost-efficiency of ESG data extraction, enabling organizations to achieve robust compliance and foster greater transparency. Our framework addresses the critical need for auditable, structured data from complex regulatory documents.

Challenges in ESG Data Management

ESG disclosure frameworks mandate reporting numerous metrics embedded in lengthy, unstructured PDF documents. Manual extraction is unscalable, while unconstrained Large Language Models (LLMs) often produce inconsistent entities, hallucinated relationships, missing provenance, and high validation failure rates. Existing ESG ontologies often lack the natural-language descriptions needed for modern AI systems, leading to difficulties in interpretation, standardization, and auditability.

A Novel Ontology-Guided Approach

OntoMetric is a three-stage, ontology-guided framework that transforms ESG regulatory text into validated, provenance-preserving knowledge graphs. Its pipeline includes: (1) structure-aware segmentation using table-of-contents boundaries; (2) ontology-guided LLM extraction with ESGMKG definitions and semantic enrichment; and (3) a two-phase validation combining LLM-based semantic verification with rule-based schema checking.

Robust Two-Phase Validation

The framework employs a rigorous two-phase validation architecture. Phase 1 involves LLM-based semantic verification to check if extracted entities' labels and descriptions match their assigned ESGMKG types. Phase 2 applies six rule-based schema validators (VR001-VR006) to enforce structural constraints across entity, property, and relationship levels, ensuring high data quality and audit traceability.

Superior Accuracy & Efficiency

Evaluation across five diverse ESG standards demonstrates OntoMetric's superior performance, achieving 65-90% semantic accuracy and 80-90% schema compliance, a dramatic improvement over the 3-10% semantic accuracy of baseline unconstrained extraction. This leads to a significantly reduced cost waste ratio and a cost of just $0.01-$0.02 per validated entity.

The Power of Ontology-Guided AI

OntoMetric demonstrates that combining symbolic ontology constraints with neural extraction and deterministic validation provides a practical pattern for building trustworthy AI systems. This hybrid approach transforms LLMs from unreliable extractors into auditable knowledge graph builders suitable for high-stakes regulatory applications, supporting sustainable-finance analytics and automated compliance tools. The rich graph structure enables downstream applications like linked data or APIs, driving greater transparency and informed decision-making in the ESG domain.

Your OntoMetric Implementation Roadmap

A clear path to integrating ontology-guided AI for superior ESG data management.

Phase 1: Structure-Aware Segmentation

Transform unstructured PDFs into coherent, context-preserving segments using table-of-contents boundaries. This phase extracts text, tables, and metadata for high-fidelity processing.

Phase 2: Ontology-Guided LLM Extraction

Apply ESGMKG ontology schema and semantic fields to guide LLM extraction of structured entities and relationships. This stage ensures schema-aligned outputs and enriches entities with contextual detail.

Phase 3: Two-Phase Validation

Implement LLM-based semantic verification and rule-based schema checking (VR001-VR006) to enforce data quality and structural consistency, producing a validated, audit-ready knowledge graph.
