Enterprise Knowledge Graph Grounding for Multi-Source RAG Systems
Architected Glean's enterprise intelligence engine, coupling deep permissions-aware crawling of 100+ SaaS applications with dense vector embeddings and a dynamic enterprise knowledge graph for sub-second grounded generative question answering.
Maintaining real-time permission sync across complex Active Directory, Okta, and SaaS permission structures introduces significant distributed indexing overhead.
Context: Hybrid sparse-dense retrieval, enterprise permissions ACL enforcement, LLM synthesis.
View missionWhy Search is the Hardest and Most Critical Foundation for Enterprise Generative AI
Authored technical analysis demonstrating that generative LLM outputs in corporate settings are only as accurate as the underlying retrieval precision, detailing why semantic vector search alone fails without enterprise graph metadata.
Synthesized enterprise answers risk exposing sensitive internal corporate gossip or draft documents unless strict contextual access filtering is applied.
Context: Vector retrieval, semantic search, precision@k metrics, context window stuffing vs targeted synthesis.
