Enterprise RAG & Knowledge Intelligence Platform

An AI-powered knowledge platform for navigating large collections of complex enterprise documents using semantic retrieval and generative AI.

AWSS3TextractPythonBedrockEmbeddingsVector SearchRAGLLMs
Overview

A retrieval platform that turns unstructured enterprise documents into an answerable knowledge layer. Ingestion, extraction, embedding and retrieval are engineered as independent stages so each can be tuned, monitored and replaced without rewriting the system.

Problem

Critical operational knowledge lives inside thousands of long, inconsistently formatted documents. Keyword search returns documents, not answers, and generic LLM interfaces hallucinate when they are not grounded in the organization's own content.

Impact
  • Transforms unstructured enterprise documents into searchable organizational intelligence
  • Answers are traceable to their source passages
  • Retrieval quality is measurable rather than anecdotal

Engineering Decisions

Structure-aware chunking

Chunks follow document structure — sections, tables and headings — instead of fixed character windows, which measurably improves retrieval precision.

Metadata-first retrieval

Metadata filters narrow the candidate set before semantic similarity runs, keeping retrieval fast and scoped to the right document class.

Grounding over fluency

Every generated answer carries its source passages. If retrieval confidence is low, the system says so rather than generating.

Stateless orchestration

Retrieval and generation run behind stateless APIs so throughput scales horizontally and failures are isolated per request.

Challenges & Solutions

Table-heavy documents

Tables lose meaning when flattened to text. Extraction preserves row/column relationships and serializes them into retrieval-friendly representations.

Retrieval quality drift

An evaluation harness scores retrieval on a curated question set so chunking and embedding changes can be compared objectively.

Cost control

Caching, candidate re-ranking and context budgeting keep token spend predictable at scale.

Key Learnings
  • Retrieval quality — not model choice — is the dominant factor in RAG output quality
  • Evaluation infrastructure must exist before tuning begins
  • Document structure is signal; discarding it discards accuracy
