Government Child Safety Department Policy Assistant

State Government Child Safety Department Policy Assistant

📋 Project Overview

We developed a RAG (Retrieval-Augmented Generation) architecture-based policy consultation chatbot for a state government child safety department, primarily serving internal case workers. These employees handle numerous cases daily and frequently need to accurately reference relevant policy provisions in their responses. Even the most experienced case workers encounter policy knowledge gaps, as the policy content is extensive and frequently updated. By deploying this intelligent policy assistant, we transformed traditional manual policy queries into an AI-driven system with second-level response times, successfully integrated into the client's Microsoft 365 Portal workflow.

🚀 Key Features

Core Implementation

  • Intelligent Policy Crawling System: Developed a Selenium-based web crawler to automatically scrape and update all policy information
  • RAG Architecture Implementation: Semantic segmentation and vectorization of policy documents, building a retrieval-augmented generation system based on Azure AI Search
  • Multimodal Interactive Interface: Integrated Azure Cognitive Services Speech, supporting natural interaction with voice input and output
  • Source Tracing Mechanism: Provides precise policy source citations and provision location, ensuring answer traceability
  • Flask Web Application: Built frontend using HTML/CSS/JavaScript, providing API services through Flask framework

Technical Highlights

  • Deep Azure Cloud Services Integration: Leveraged Azure OpenAI Service, Azure AI Search, and Azure Blob Storage to build enterprise-grade AI infrastructure
  • Precise RAG Retrieval: Achieved semantic similarity search through vector database, significantly improving policy matching accuracy
  • Real-time Speech Processing: Integrated Azure Speech Services, supporting bidirectional conversion between speech-to-text and text-to-speech
  • Microsoft Ecosystem Integration: Seamlessly integrated into Microsoft 365 Portal, becoming an organic component of daily workflows

💻 Project Detail

Our policy assistant system addresses the core pain points of government knowledge management. The specific implementation process is as follows:

  1. Policy Data Collection: Used Selenium web crawler to periodically scrape policy websites, automatically identify updated content and save to Azure Blob Storage
  2. Intelligent Document Processing:
  3. Utilized PyMuPDF to extract text content from PDF policy documents
  4. Applied Document Chunking techniques to segment long documents into semantically coherent fragments
  5. Generated high-quality vector representations using Azure OpenAI embedding models
  6. RAG Retrieval System Construction:
  7. Established vector database in Azure AI Search, storing embeddings of all policy fragments
  8. Implemented semantic retrieval based on cosine similarity, ensuring relevance matching
  9. Built Fast API interfaces providing policy matching and answer generation services
  10. Multimodal Frontend Interaction:
  11. Developed HTML/CSS/JavaScript frontend interface providing intuitive chat experience
  12. Integrated Azure Speech Services, enabling users to ask questions via voice and receive voice responses
  13. Implemented real-time conversation state management and history tracking
  14. Microsoft 365 Integration Deployment:
  15. Containerized deployment to Azure App Service using Docker
  16. Integrated into client's existing Microsoft 365 Portal workflow
  17. Provided SSO single sign-on and permission management

The entire system ensures AI responses are both accurate and meet government professional requirements through carefully designed prompt engineering.
