We discuss how to infuse Large Language Models (LLMs) with Knowledge Graphs (KGs)! This is a very exciting approach, as we can combine the flexibility and generalisability of LLMs with the structure and reliability of KGs, and is a first step towards neurosymbolic architectures!

I will also be going through a LangChain implementation of LLMs with knowledge graphs as inputs, demonstrate some of the limitations currently faced, and show how we can better prompt engineer KG usage with LLMs using my very own StrictJSON Framework.
