Neurosymbolic AI with LLMs and Knowledge Graphs
This talk outlines a neurosymbolic approach—combining neural LLMs with symbolic knowledge graphs and ontologies—for practical data-science workflows. We’ll introduce GraphRAG: building a graph from your corpus and using graph structure and summaries to retrieve context, contrasted with text-only RAG. We’ll then use ontologies and SHACL constraints as machine-checkable contracts to scope prompts and validate model outputs. Finally, we’ll discuss using LLMs for entity harmonization and for bootstrapping vocabularies/ontologies, with notes on accuracy, cost, and human oversight. For context, we’ll situate these patterns in recent work on neurosymbolic AI.
