How can we further increase the accuracy of LLM-powered question answering systems? Ontologies to the rescue! That is the conclusion of the latest research coming from the @datadotworld AI Lab with @WorkingOntology Paper: arxiv.org/abs/2405.11706 🧵 describing the results
The real winners of the AI wave? The companies that quietly invested 5–10 years in metadata, semantics, and knowledge graphs. At @Connected_Data London, every talk showed real revenue, cost, and ops gains. No POCs. Maturity and production. A clear divide is emerging: strategists…
How AI triggered a "semantic war": the fight over metadata standards and why it matters
We are in a data bubble — how joining ServiceNow has been exposing us to the blind spots every data team has
Two Meanings of “Semantic Layer” and Why Both Matter in the Age of AI Everyone’s talking about semantic layers, but not everyone means the same thing. On the analytics side, semantic layer usually refers to something we’ve seen before. It’s the business-friendly model that sits…
The O-word, “ontology” is here! Traditionally, you couldn’t say the word “ontology” in tech circles without getting a side-eye. Now? Everyone’s suddenly an ontology expert. And honestly… I’m here for it. But here’s the thing: before we reinvent the wheel, we need to understand…
𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗚𝗿𝗮𝗽𝗵𝘀 didn’t just appear with Google in 2012. Their story began decades earlier. 🧠 Inspired by @juansequeda & Claudio Gutierrez’s piece: cacm.acm.org/research/knowl… I built an interactive timeline 👇 wor.ai/BNmsRc
OpenAI doesn’t know what they want to be when they grow up. Enterprise or Consumer? I think they will end up being consumer while Anthropic will be the enterprise offering. We shall see.
Three Stop-Start that the data & analytics community should consider 1) Stop doing just analytics. Start building feedback loops from analytics to operations 2) Stop focusing only on BI semantic layers. Start building your enterprise ontology 3) Stop staying in the data bubble.…

Tired of boiling the ocean with data governance? 🌊 Try the Pay-As-You-Go Methodology: Start small → Deliver value → Repeat. 1️⃣ Capture knowledge. Start with 1 question 2️⃣ Implement Knowledge 3️⃣ Reuse it 1 unit of work → 10+ questions answered. That’s leverage. That’s scale.
What the heck is semantics? Semantics 🕸️ = Business 💼 + Technical 🛠️ + Mapping 🔗 Metadata
Grit and Luck!
I still don’t understand how I got lucky enough to go from growing up in Guatemala to co-founding a public company. Grateful every day, and sometimes still confused by it.
