About this paper

Thanh Luong Tuan, Abhijit Sanyal

This research introduces a neurosymbolic architecture for enterprise AI agents, integrating a formal three-layer ontology (Role, Domain, Interaction) with Large Language Models. It empirically demonstrates improved performance in domain-specific reasoning, regulatory compliance, and role consistency, especially in domains with sparse LLM training data and for enterprise-specific metrics.

Key insights

  • The "Inverse Parametric Knowledge Effect" (Inverse PKE) indicates that ontological grounding provides the greatest value where an LLM's pre-existing parametric knowledge is weakest, such as for highly specialized enterprise metrics or less represented languages/domains.
  • Formal enterprise ontologies significantly enhance an agent's ability to achieve high Metric Accuracy and Role Consistency by providing structured definitions for domain-specific KPIs and decision patterns.
  • While RAG with curated chunks can perform comparably for lexical recall, the structural and relational grounding provided by formal ontologies offers a distinct advantage for complex reasoning tasks.
