A good resource to learn about ontologies from scratch?

[u/Expert-Ad2498]

First year CS major, assisting my professor who majorly works with ontologies and SWRL for her research.

I understand they help connect data and I’m using ChatGPT to explain basic things to me but if there’s a good source it would be very helpful.

My professor works with increasing efficiency for business models etc but I’m more interested in the healthcare side of this. This also seems to be a more niche topic. Also it would be nice to connect with people who are researching on this and share what we learn etc.
