Why Enterprise AI Agents Fail: Ontology, Semantic Layer & Knowledge Graphs
Your AI agent has access to every table in the warehouse, and it still gets simple business questions wrong. It picks the wrong table, uses the wrong formula, guesses what "South India" means, and can't tell you why a number changed. In this live session we untangle four terms everyone mixes up and show why enterprise AI needs all of them: 🔵 Data Catalog: which data should we use? 🟢 Semantic Layer: which definition, and how do we calculate it? 🟣 Enterprise Ontology: what does it mean, and what are the rules? 🟠 Knowledge Graph: what is connected to what? Demo stack - Ontology: RDF / OWL (Turtle), queried with rdflib + SPARQL - Knowledge graph: Neo4j - Semantic layer: YAML metric definitions compiled to SQL - Data catalog: owners, freshness, lineage, certification - Agent: OpenAI-compatible tool calling, FastAPI We follow one question the whole way: "Why did South India revenue drop last month?" First I explain each layer on the whiteboard. Then I show it live in a working demo where you can switch each layer on and off and watch the agent fail or succeed. What you'll learn - Why raw data access isn't enough for AI agents - Business glossary vs taxonomy vs ontology - Semantic layer vs ontology: numbers vs meaning - RDF/OWL vs property graphs (and why teams use both) - Multi-hop reasoning: customers → products → suppliers → warehouses - How to tell which layer your company is missing from the way your AI fails Chapters 00:00 Intro 03:00 The stumbling agent (live, no context) 08:00 Four layers in one sentence each 12:00 Data Catalog 18:00 Semantic Layer 25:00 Enterprise Ontology 32:00 Knowledge Graph 38:00 Glossary vs taxonomy vs ontology 42:00 Semantic layer vs ontology 45:00 RDF vs property graph 48:00 The agent walks all four layers (live comparison) 53:00 Which layer is your company missing? 56:00 Q&A 👍 Like, subscribe and turn on notifications for more on AI agents, RAG and enterprise AI.
