The Challenge

A global organization operating under strict marketing regulations needed to automate compliance review for images, PDFs, videos, and audio files. Traditional manual processes created bottlenecks, while early AI experiments produced unreliable outputs that hallucinated rules and failed audit requirements.

Why Standard RAG Failed

Context contamination when mixing document types

Models invented compliance positions that didn't exist

Ambiguous regulatory language caused contradictions

No traceability to source documents

"Success required deliberate orchestration, not plug-and-play automation."

The Five-Stage RAG Pipeline

1
Content Extraction
PDF/Video/Audio → Text
2
Context Retrieval
Segmented by doc type
3
Prompt Generation
Two-phase reasoning
4
LLM Validation
GPT-4o with citations
5
Audit Storage
Complete traceability

The Breakthrough: Document-Type Segmentation

Generic RAG failed because retrieving all document types together caused context contamination. We segmented by type (claims, rules, training, dossiers) with weighted retrieval.

Before
Mixed context
60% accuracy
After
Segmented retrieval
94% accuracy

Solving the Hard Problems

Hallucination Prevention

Models invented rules. Solution: Mandatory citation to source documents with SharePoint URL tracking. Every compliance judgment must include direct quotes with hyperlinks. If the model can't provide a source, the response is rejected.

Prompt Governance

Success came after 47 iterations. Prompt versioning and A/B testing became critical. We treat prompts as code: version control, peer review, performance metrics, and rollback capability. Two-phase prompting improved consistency by 35%.

Multimodal Processing

Handled PDFs, images, video, and audio through Azure Document Intelligence and Video Indexer. Each content type has a specialized extraction pipeline. Video transcripts include speaker identification and timestamp indexing.

Security & Compliance

Row-level security, complete audit trails, and role-based access for regulated environment. Every API call is logged with user context. Data residency requirements met through Azure region selection. SOC 2 Type II compliant.
