Context Aware AI Routing Engine for Real Time Vendor Questionnaire Assignment
Security questionnaires and compliance audits are a constant source of friction for SaaS vendors. The sheer variety of frameworks—SOC 2, ISO 27001, GDPR, HIPAA, and dozens of industry‑specific checklists—means that each incoming request can require expertise from security engineers, legal counsel, product managers, and even data‑science teams. Traditional manual triage creates bottlenecks, introduces human error, and leaves no clear audit trail.
Procurize tackles this problem with a Context‑Aware AI Routing Engine that automatically assigns each questionnaire—or even individual sections—to the most appropriate owners in real time. The engine leverages large‑language‑model (LLM) inference, a dynamic knowledge graph of internal expertise, and a reinforcement‑learning‑based workload balancer. The result is a self‑optimizing system that not only speeds up response times but also continuously improves routing accuracy as the organization matures.
Why Real‑Time, Context‑Driven Routing Matters
| Pain Point | Conventional Approach | AI‑Powered Solution |
|---|---|---|
| Latency – Teams often wait hours or days for a ticket to be manually assigned. | Email or ticket‑system hand‑offs. | Immediate assignment within seconds after questionnaire ingestion. |
| Mis‑matching – Answers are drafted by owners lacking deep domain knowledge, leading to re‑work. | Guesswork based on job titles. | Semantic matching using LLM‑derived intent and knowledge‑graph provenance. |
| Workload Imbalance – Some owners are overloaded while others sit idle. | Manual load monitoring. | Reinforcement‑learning scheduler that equalizes effort across the team. |
| Auditability – No trace of why a particular owner was chosen. | Ad‑hoc notes. | Immutable routing logs stored in a provenance ledger. |
By addressing these challenges, the routing engine becomes a critical first line of defense in the compliance pipeline, ensuring that every answer starts its journey with the right hands.
Architectural Overview
The routing engine is built as a micro‑service that plugs into Procurize’s existing questionnaire hub. Below is a high‑level diagram of the data flow.

Key Components
- Document AI Ingestion – Uses OCR and structured parsers to convert PDFs, Word docs, or JSON payloads into a normalized text format.
- Semantic Chunking & Intent Extraction – An LLM (e.g., GPT‑4o) segments the questionnaire into logical sections (e.g., “Data Retention”, “Incident Response”) and generates intent embeddings.
- Expertise Knowledge Graph – A graph database (Neo4j or TigerGraph) stores nodes representing employees, their certifications, past answered sections, and confidence scores. Edges capture expertise domains, workload history, and regulatory specialties.
- Reinforcement Learning Scheduler – A policy‑gradient model observes routing outcomes (acceptance rate, turnaround time, quality score) and iteratively improves the assignment policy.
- Assignment Notification Layer – Integrates with collaboration tools (Slack, Microsoft Teams, email) and updates Procurize’s UI in real time.
- Audit Log – Writes a tamper‑evident record to an append‑only ledger (e.g., blockchain‑based or AWS QLDB) for compliance auditors.
Step‑By‑Step: How the Engine Routes a Questionnaire
1. Ingestion & Normalization
- The questionnaire file is uploaded to Procurize.
- Document AI extracts raw text, preserving hierarchical markers (sections, subsections).
- A checksum is stored for later integrity verification.
2. Intent Extraction
- The LLM receives each section and returns:
- Section Title (standardized)
- Regulatory Context (SOC 2, ISO 27001, GDPR, etc.)
- Confidence‑Weighted Embedding (vector representation)
3. Knowledge‑Graph Query
- The embedding vector is matched against the expertise graph using cosine similarity.
- The query also filters by:
- Current Workload (tasks assigned in the last 24 h)
- Recent Success Rate (answers that passed audit)
- Compliance Scope (e.g., only team members with GDPR certification for privacy sections)
4. Scheduler Decision
- The RL scheduler receives a set of candidate owners and selects the one that maximizes an expected reward: [ R = \alpha \times \text{Speed} + \beta \times \text{Quality} - \gamma \times \text{Load} ]
- Parameters (α, β, γ) are tuned per organization policy (e.g., prioritize speed for time‑critical deals).
5. Notification & Acceptance
- The chosen owner receives a push notification with a direct link to the section in Procurize.
- An acceptance window (default 15 min) allows the owner to decline and trigger a fallback selection.
6. Audit Trail Capture
- Every decision, along with the embedding and graph query snapshot, is written to the immutable ledger.
- Auditors can later replay the routing logic to verify compliance with internal SLAs.
AI Models Behind the Scenes
| Model | Role | Why It Fits |
|---|---|---|
| GPT‑4o (or comparable) | Intent extraction, natural language summarization | State‑of‑the‑art understanding of regulatory language; few‑shot prompting reduces custom fine‑tuning. |
| Sentence‑Transformer (SBERT) | Embedding generation for similarity search | Produces dense vectors that balance semantic richness with retrieval speed. |
| Graph Neural Network (GNN) | Propagation of expertise scores across the knowledge graph | Captures multi‑hop relationships (e.g., “John → managed PCI‑DSS audit → knows encryption standards”). |
| Policy Gradient RL (Proximal Policy Optimization) | Real‑time routing policy optimization | Handles non‑stationary environments where workload and expertise evolve daily. |
All models are served via a model‑as‑a‑service layer (e.g., NVIDIA Triton or TensorFlow Serving) to ensure low latency (<200 ms per inference).
Integration With Existing Procurize Workflows
- API Contract – The router exposes a RESTful endpoint (
/api/v1/route) that accepts normalized questionnaire JSON. - Webhooks – Procurize’s UI registers a webhook that triggers on “questionnaire uploaded” events.
- User Profiles Sync – HRIS (Workday, BambooHR) syncs employee attributes to the expertise graph nightly.
- Compliance Dashboard – Routing metrics (average latency, success rate) are visualized alongside existing answer quality dashboards.
- Security – All traffic is secured with mutual TLS; data at rest is encrypted using customer‑managed keys.
Measurable Benefits
| Metric | Before Routing Engine | After Deployment (3 months) |
|---|---|---|
| Mean Assignment Latency | 4.2 h | 3.5 min |
| First‑Pass Answer Quality Score (0‑100) | 71 | 88 |
| Owner Over‑Allocation Events | 12 per month | 1 per month |
| Audit Trail Retrieval Time | 2 days (manual) | <5 seconds (automated query) |
| User Satisfaction (NPS) | 38 | 71 |
These numbers are based on early adopters in the fintech and health‑tech sectors, where compliance velocity is a competitive differentiator.
