SA-RAG explores graph activation for evidence retrieval
Published on December 20, 2025, the paper presents SA-RAG, which propagates activation across weighted knowledge-graph connections to retrieve documents linked to relevant entities.

What happened and what to do
Published on December 20, 2025, the paper describes SA-RAG, a retrieval approach for knowledge-graph-based RAG. Activation starts from entities associated with a query and spreads across weighted connections, helping retrieve documents linked to highly activated entities. The approach is an alternative to LLM-guided iterative retrieval for finding connected evidence in multi-hop questions.
A company can assess whether its internal search needs to connect evidence distributed across documents and entities. A project could map sources and relationships, implement graph indexing and an update pipeline, and compare retrieval with the current process on representative queries.
How the consultancy can help
Wendelmaques can diagnose sources, queries, and retrieval gaps; define a scoped implementation of graph indexing and retrieval; and plan its operation and monitoring.
