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

My Honest No-BS Takeaways from @Gartner_inc D&A London May 2026: yeah context is king and queen, but everyone is still at the basics, governance should also be king and queen, figuring out your vendor strategy is critical too and no talks about methodologies. open.substack.com/pub/juansequed…

Last time I was in Vienna was 2017 and I found this picture. That was my company (@Capsenta) and our software (Ultrawrap). The tagline states: “Changing the way the world models, governs and integrates data” Talk about determination and passion. Let’s go!!!

25 years ago today, the seminal Semantic Web article by @timberners_lee @jahendler @oralassila was published in Scientific American. If you’re building agents, knowledge graphs and now context layers today, my ask is simple: read the original Semantic Web article.

@ToBeJazz Expand please maybe this is the case of code being data?

@juansequeda My ontology is never represented in code, only in data.

Starting to work with ontologies? Think about these two dimensions: WHAT (Formal, Explicit and Shared Meaning) and WHY (Interoperability, Automation). juansequeda.substack.com/p/juan-and-tim…

Beyond Context Graphs: How Ontology, Semantics, and Knowledge Graphs Define Context What are context graphs, what are they good for, and why are they dubbed AI’s trillion-dollar opportunity? What does context mean actually, and how can it be defined using graphs and ontologies? And how can different types of graphs and graph technologies power AI? Gartner highlighted Data Management, Semantic Layers, and GraphRAG as Top Trends in Data and Analytics for 2026. Startups and incumbents in the graph technology space are making progress, while graph is becoming the fastest growing segment in AI research. A comprehensive, up-to-date repository, visualization, and analysis of offerings across the graph technology space has been unveiled. New and existing combinations of Graphs and AI are being used to power use cases such as software engineering productivity and supporting enterprise needs at Netflix scale. New graph database products, features, and benchmarks are available. Use cases as well as research and development on ontologies are on the rise too, including topics such as Enterprise Architecture, visual tooling, and quality assessment for LLM-assisted use of ontologies. And yet, the most widely discussed topic in the world of graph technology – and beyond – for this past couple of months has been context graphs. So what are context graphs and where do they fit in the graph technology landscape? In this issue of the Year of the Graph, we explore progress in Ontology, Semantics, Knowledge Graphs, Graph Databases and Analytics, and how these technologies can help define context and power AI.
