Ontology-Driven Data Governance: From Metadata to Business Semantics for AI Agents

The article argues that traditional master data and metadata management only achieve data visibility and traceability, while ontology-driven governance adds a computable business semantic layer—modeling objects, processes, states, rules, and actions via OPM and ontology—to enable AI agents to execute tasks reliably within real business contexts.

Piloting a Judicial Semantic Platform: 6 Steps from Semantic Model to Controlled AI Agent

This article outlines a six-step methodology for piloting a judicial semantic platform: freeze a runnable semantic model using OPM, integrate minimum necessary data, run case object views, build a business-oriented front-end, integrate a controlled AI Agent with audit logging, and validate via a five-dimensional acceptance loop before scaling.

Why Judicial Semantic AI Platforms Must Start with a Single Case Pilot

The article argues that judicial semantic intelligence platforms should avoid full-scale initial deployment and instead begin with a pilot on a single case type to define clear data, metric, permission, and AI agent boundaries, run a verifiable closed loop, and then expand by reusing semantic models across case types, execution domains, and management dashboards.

Building Industry AI Semantic Foundations: MBSE Guides OPM & Ontology

The article argues that an industry AI semantic foundation requires MBSE to define system boundaries and verification loops, OPM to model objects, processes, and state changes, and ontology to consolidate unified semantic assets, providing a five-step implementation path for continuous model-data resonance.

Police AI Beyond Document Generation: Semantic Understanding of Interrogations, Evidence & Processes

This article argues that police AI's true value lies not in document generation but in semantic platforms that understand interrogation records, link evidence chains, and embed into case-handling workflows, shifting from post-hoc correction to real-time, controlled assistance across investigation, approval, and archival stages.

Building a Police AI Semantic Foundation: Six-Layer Architecture for Law Enforcement Case Handling

The article outlines a six-part architecture for a public security AI semantic foundation centered on the law enforcement case handling platform, integrating 110 alarm input, police data exchange, case materials, semantic modeling via OPM and ontology, node-specific AI agents, and supervision analytics, all governed by cross-cutting security, permission, and audit controls.
