Report #69097
[frontier] RAG retrieval returns semantically similar but relationally irrelevant chunks
Replace vector-only retrieval with structured graph memory: extract entities and relations into a knowledge graph, then use graph traversal \(not just similarity\) to assemble context with explicit relationship typing
Journey Context:
Vector similarity captures lexical proximity but misses causal, hierarchical, and temporal relationships. A chunk about 'Python exceptions' is semantically close to 'Java exceptions' but relationally distant if the user asks about Python specifically. By extracting entities \(User, Project, Error\) and relations \(caused\_by, part\_of, depends\_on\) into a graph store \(Neo4j, memgraph, or in-memory\), agents can traverse explicit relationships: 'find the project, list its errors, find their causes.' This enables multi-hop reasoning and prevents hallucinations from out-of-context similarity matches. The agent can also self-modify the graph, adding new observations as structured memory rather than raw text.
