Intelligent Document Q&A Query Workflow
This workflow automatically downloads PDF documents from Google Drive and splits the content, converting the text into vectors stored in the Qdrant database. It utilizes OpenAI's GPT-4 model to enable intelligent Q&A. Users can submit queries through a Webhook, and the system provides real-time, accurate answers based on the document content, significantly enhancing document retrieval efficiency and knowledge management capabilities. It is suitable for various scenarios such as corporate knowledge bases, customer support, and research data analysis.
Workflow Name
Intelligent Document Q&A Query Workflow
Key Features and Highlights
This workflow enables downloading PDF documents from Google Drive, automatically splitting them, and inserting the data into the Qdrant vector database. It then leverages OpenAI’s GPT-4 model to perform intelligent Q&A based on vector retrieval. The system supports receiving user queries via Webhook and provides real-time, accurate answers grounded in the document content. The process is fully automated and integrates efficient text splitting and vector storage technologies to ensure effective indexing of large documents and rapid response times.
Core Problems Addressed
Traditional document querying methods are inefficient and struggle to support natural language intelligent Q&A. This workflow solves the challenges of automatic splitting, vectorized storage, and semantic-based efficient retrieval of large-scale document content. It helps users quickly extract key information from documents, significantly enhancing knowledge management and information access efficiency.
Application Scenarios
- Intelligent Q&A for enterprise internal knowledge bases
- Rapid retrieval of specialized documents such as financial and legal materials
- Automated document-based response systems in customer support
- Intelligent analysis of research materials and reports
- Any scenario requiring the transformation of large volumes of documents into a searchable knowledge base
Main Process Steps
- Manually trigger the workflow to initiate document processing
- Download specified PDF files (e.g., crowdstrike.pdf) from Google Drive
- Split the PDF into appropriately sized text chunks using the default data loader and recursive character text splitter
- Convert text chunks into vectors using the OpenAI Embeddings node
- Insert vector data into the Qdrant vector database to build indexes
- Receive user query requests via Webhook
- Retrieve relevant text vectors from Qdrant using a vector searcher
- Execute a Q&A chain with the OpenAI GPT-4 model based on the retrieval results to generate answers
- Return answers to users in real time through the Webhook response node
