You're very welcome!

This was so helpful, thank you so much!!! I still don't understand how the LLM knows what the Nodes are and how they are related, especially for a company with their own taxonomy. Do you have to pass that info to the LLM to provide context? Or does the Lanchain RAG functions inherently do that? Thanks, great series!

@jbarrasa4649 6 месяцев назад

In our case, the KG offers you a `pathsim.search` method that is taxonomy-aware. So if you store your taxonomy in your KG in a standard way, then you can leverage it for "graph semantic similarity" using the available functions (like `pathsim.search` and others) or even through custom exploration. That's the retrieval part of the RAG pattern, and therefore the LLM does not need to be aware of it. All the LLM receives is the result of the exploration in the graph in the form of context. I hope it makes sense?

Informative ! though it would be nice if the screen resolution was as good as your photos 🙂 The graph and LLM seem to be too intertwined to get it to work. Maybe you should try to create a toolkit to ease thing for the users for the entire pipeline required.

Sorry - we should have zoomed in a bit more!
