Indexing Knowledge Graphs with the GraphRAG Toolkit | Amazon Web Services

AWS published a tutorial on using GraphRAG Toolkit to build a lexical graph index from unstructured documents.

The workflow covers statement extraction, entity and topic detection, graph construction, and vector embedding.

It also shows flexible execution modes for combining graph and vector stores in retrieval pipelines.

The approach can surface relationships and context that vector-only RAG may miss, improving search over complex data.
