I agree that understanding data structure and context is the biggest challenge to using AI effectively for data analysis. Right now, I find myself shying away from using AI because I have to spend so much time explaining context and business rules/logic to get a useful output. I'd love to see a follow-up video showing how to get started building a semantic layer on top of existing tables.

I have worked with semantic models for a while already and what you said about politics is extremely true. Additionally, quite some colleagues don't really see any value in this direction and it doesn't feel good, although I find this work genuinely exciting and meaningful

So the layers are Date -> Semantic model (data model) -> Semantic Layer -> Ontology layer ?

I found the holy grail of behavioural layers, turning stochastic into determinism. Currently testing it in a project. Thinking how to divulge it and maybe writing something more academic

Sounds fun, like Data Dictionary for AI.

Is Semantic Layer and Ontology Layer the same or different?
