Knowledge Graph for Beginners

About this course

Knowledge graphs are reshaping how organisations store, connect and reason with data. Here's where your journey starts.If you've tried to learn about knowledge graphs before, you'll know the problem: the available materials tend to be scattered, highly technical and written for people who are already halfway there. This course was built to fix that — a carefully curated, accessible introduction that gives complete beginners a genuine foothold in one of the most exciting areas of modern data technology.So what exactly is a knowledge graph? At its core, it's a network of facts connected through explicitly defined relationships — one that doesn't just store data, but allows new knowledge to be inferred from it. Underpinning knowledge graphs is a technology stack that unlocks powerful capabilities: tearing down data silos, richly representing data and metadata, embedding meaning into computation through semantics, and driving next-generation AI and analytics.Organisations across manufacturing, telecommunications, IT, mass media, financial services, pharmaceuticals and beyond are already applying knowledge graph technology to power their data strategies and digital transformation. Increasingly, knowledge graphs are also playing a critical role in making AI work reliably over enterprise data — providing the structured, semantically rich foundation that grounds large language models, reduces hallucinations and enables AI systems to reason over real organisational knowledge rather than generic training data. Knowledge graphs sit at the heart of Industry 4.0, Digital Twins, explainable AI and intelligent decision support — and understanding them is fast becoming an essential skill for any data professional.What you will be able to do after this course:Explain what knowledge graphs are and articulate why they matter to modern organisationsSpeak confidently using the vocabulary of knowledge graphs, ontologies and semantics
