Enterprise AI / Knowledge Retrieval
Knowledge Intelligence & GraphRAG
Hybrid search and connected knowledge turn scattered documents into grounded, traceable answers.

THE ENGINEERING STORYFrom complexity
From complexity
to capability.
The challenge
Retrieve relevant context across documents and relationships, then make the source of each answer understandable.
Engineering contributions
- Expanded hybrid retrieval with graph-based and multimodal approaches.
- Represented knowledge relationships in Neo4j and integrated pgvector semantic retrieval.
- Applied query decomposition, metadata filtering, and reranking.
- Supported source-grounded answer generation within the broader Vertex platform.
Performance & reliability
Retrieval relevance improved from 76% to 85% across the broader knowledge platform work.
