Enterprise RAG Architecture & Knowledge Intelligence
Enterprise knowledge is deeply fragmented across legacy databases, isolated file shares, document repositories, and communication channels. Moving beyond basic vector search, production-grade Retrieval-Augmented Generation (RAG) systems demand contextually grounded architecture to combat hallucinations and deliver verifiable enterprise accuracy.
Vakratron Systems engineers end-to-end cognitive extraction fabrics. Our pipelines ingest, structure, embed, and dynamically serve enterprise state data straight to planning models, enforcing strictly scoped document permissions and real-time authority filters.
Ingestion Layer
Storage & Indexing
Synthesis Layer
Document Ingestion & Advanced Chunking
Our ingestion frameworks break down unstructured multi-format data (PDFs, Docs, Scans) without losing structural orientation or table dependencies.
- Semantic & Layout-Aware Chunking
- Hierarchical Parent-Child Indexing
- OCR & Multi-Modal Document Parsing
- Metadata Enrichment Pipelines
- Sliding Window Token Tokenization
- Automated Document Delta Scanning
Hybrid Retrieval Strategy
Combining the dense conceptual tracking of vector embeddings with the strict literal filtering of keyword-based keyword matching.
- Dense Vector Embedding Search
- Sparse BM25 Keyword Matching
- Cross-Encoder Deep Re-ranking
- Query Intent Analysis & Expansion
- Hypothetical Document Embeddings (HyDE)
- Reciprocal Rank Fusion (RRF) Blending
Knowledge Graph RAG (GraphRAG)
Maps abstract data correlations as structured nodes and categorical relationships, allowing deep contextual multi-hop query analysis.
