There’s a lot of buzz about #semanticlayers on LinkedIn these days. So what is a semantic layer? According to AtScale, “The semantic layer is a metadata and abstraction layer built on the source data (eg.. data warehouse, data lake, or data mart). The metadata is defined so that the data model gets enriched and becomes simple enough for the business user to understand.” It’s a metadata layer. Which can be taken a step further. A metadata layer is best implemented using metadata standards that support interoperability and extensibility. There are open standards such as Dublin Core Metadata Initiative and there are home-grown standards, established within organizations and domains. If you want to design and build semantic layers, build from metadata standards or build a metadata standard, according to #FAIR principles (findable, accessible, interoperable, reusable).

After publishing my article on the Missing Semantic Center, a brilliant colleague asked me a question that gets to the heart of our technology stack: "But Tavi - this doesn't look like an OWL 2 DL ontology. What's going on here?" This question highlights a profound aspect of why systems have struggl

I've been working on autonomous AI systems, and wanted to share some thoughts on what I believe makes them effective. The challenge isn't just making AI that follows instructions well, but creating systems that can reason, and act independently.

🧠 When Is an Ontological Approach Not the Right Fit for Sharing and Reusing System Knowledge in Design and Development? Ontologies promise knowledge integration, traceability, reuse, and machine reasoning across the full engineering system lifecycle. From functional models to field failures, ontologies offer a way to encode and connect it all. 💥 However, ontologies are not a silver bullet. There are plenty of scenarios where an ontology is not just unnecessary, it might actually slow you down, confuse your team, or waste resources. So when exactly does the ontological approach become more burden than benefit? Based on my understanding and current work in this space, 🚀 For engineering design, it's important to recognise situations where adopting a semantic model is not the most effective approach: 1. When tasks are highly localised and routine If you're just tweaking part drawings, running standard FEA simulations, or updating well-established design details, then the knowledge already lives in your tools and practices. Adding an ontology might feel like installing a satellite dish to tune a local radio station. 2. When terminology is unstable or fragmented Ontologies depend on consistent language. If every department speaks its own dialect, and no one agrees on terms, you can't build shared meaning. You’ll end up formalising confusion instead of clarifying it. 3. When speed matters more than structure In prototyping labs, testing grounds, or urgent production lines, agility rules. Engineers solve problems fast, often through direct collaboration. Taking time to define formal semantics? Not always practical. Sometimes the best model is a whiteboard and a sharp marker. 4. When the knowledge won’t be reused Not all projects aim for longevity or cross-team learning. If you're building something once, for one purpose, with no intention of scaling or sharing, skip the ontology. It’s like building a library catalog for a single book. 5. When the infrastructure isn't there Ontological engineering isn’t magic. It needs tools, training, and people who understand the stack. If your team lacks the skills or platforms, even the best-designed ontology will gather dust in a forgotten folder. Use the Right Tool for the Real Problem Ontologies are powerful, but not sacred. They shine when you need to connect knowledge across domains, ensure long-term traceability, or enable intelligent automation. But they’re not a requirement for every task just because they’re clever. The real challenge is not whether to use ontologies, but knowing when they genuinely improve clarity, consistency, and collaboration, and when they just complicate the obvious. 🧠 Feedback and critique are welcome; this is a living conversation.

LLMs already contain overlapping world models. You just have to ask them right. Ontologists reply to an LLM output, “That’s not a real ontology—it’s not a formal conceptualization.” But that’s just the No True Scotsman fallacy dressed up in OWL. Boring. Not growth-oriented. Look forward, angel. A foundation model is a compression of human knowledge. The real problem isn't that we "lack a conceptualization". The real problem with an FM is that they contain too many. FMs contain conceptualizations—plural. Messy? Sure. But usable. At Stardog, we’re turning this latent structure into real ontologies using symbolic knowledge distillation. Prompt orchestration → structure extraction → formal encoding. OWL, SHACL, and friends. Shake till mixed. Rinse. Repeat. Secret sauce simmered and reduced. This isn't theoretical hard. We avoid that. It’s merely engineering hard. We LTF into that! But the payoff means bootstrapping rich, new ontologies at scale: faster, cheaper, with lineage. It's the intersection of FM latent space, formal ontology, and user intent expressed via CQs. We call it the Symbolic Latent Layer (SLL). Cute eh? The future of enterprise AI isn’t just documents. It’s distilling structured symbolic knowledge from LLMs and plugging it into agents, workflows, and reasoning engines. You don’t need a priesthood to get a formal ontology anymore. You need a good prompt and a smarter pipeline and the right EKG platform. There's a lot more to say about this so I said it at Stardog Labs https://lnkd.in/eY5Sibed | 17 comments on LinkedIn

Every year, businesses and consumers lose billions of dollars to fraud, with consumers reporting $12.5 billion lost to fraud in 2024, a 25% increase year over year. People who commit fraud often work together in organized fraud networks, running many different schemes that companies struggle to detect and stop. In this post, we discuss how to use Amazon Neptune Analytics, a memory-optimized graph database engine for analytics, and GraphStorm, a scalable open source graph machine learning (ML) library, to build a fraud analysis pipeline with AWS services.

Graph is the new star schema. Change my mind. Why? Your agents can't be autonomous unless your structured data is a graph. It is really very simple. 1️⃣ To act autonomously, an agent must reason across structured data. Every autonomous decision - human or agent - hinges on a judgment: have I done enough? “Enough" boils down to driving the probability of success over some threshold. 2️⃣ You can’t just point the agent at your structured data store. Context windows are too small. Schema sprawl is too real. If you think it works, you probably haven’t tried it. 3️⃣ Agent must first retrieve - with RAG - the right tables, columns, and snippets. Decision making is a retrieval problem before it’s a reasoning problem. 4️⃣ Standard RAG breaks on enterprise metadata. The corpus is too entity-rich. Semantic similarity is breaking on enterprise help articles - it won't perform on column descriptions. 5️⃣ To make structured RAG work, you need a graph. Just like unstructured RAG needed links between articles, structured RAG needs links between tables, fields, and - most importantly - meaning. Yes, graphs are painful. But so was deep learning—until the return was undeniable. Agents need reasoning over structured data. That makes graphs non-optional. The rest is just engineering. Let’s stop modeling for reporting—and start modeling for autonomy. | 28 comments on LinkedIn

To highlight the different uses and impact of semantics and ontologies, I wanted to present a series of interview to professionals from different industries and roles. This is going to be a distributed post.

Tired of being told that silos are gone? The real value comes from connecting them. 🔄 The myth of data silos: why they never really disappear, and how to turn them into your biggest advantage. Even after heavy IT investment, data silos never truly go away, they simply evolve. In food production, I saw this first-hand: every system (ERP, quality, IoT, POS) stored data in its own format. Sometimes, the same product ended up with different IDs across systems, batch information was fragmented, and data was dispersed in each silo. People often say, “Break down the silos.” But in reality, that’s nearly impossible. Businesses change, new tools appear, acquisitions happen, teams shift, new processes and production lines are launched. Silos are part of digital life. For years, I tried classic integrations. They helped a bit, but every change in one system caused more issues and even more integration work. I wish I had known then what I know now: Stop trying to destroy silos. Start connecting them. Here’s what makes the difference: Add a Semantic Layer – a smart translator that sits between your data sources and your business applications. It maps different formats and names into a common language, without changing your original systems. Put a Knowledge Graph on top and you don’t just translate – you connect. Suddenly, all your data sources, even legacy silos, become part of a single network. Products, ingredients, machines, partners, and customers are all logically linked and understood across your business. In practice, this means: - Production uses real sales and shelf-life data. - Sales sees live inventory, not outdated reports. - Forecasting is based on trustworthy, aligned data. That’s the real shift: Silos are not problems to kill, but assets to connect. With a Semantic Layer and a Knowledge Graph, data silos become trusted building blocks for your business intelligence. Better Data, Better ROI. If you’ve ever spent hours reconciling reports, you’ll recognise this recurring pain in companies that haven’t optimised their data integration with a semantic and KG approach. So: Do you still treat silos as problems, or could they be your next competitive advantage if you connect them the right way?
