Intelligent Document Q&A and Citation Generation Workflow Based on Google Drive Files

This workflow automatically downloads files from Google Drive, processes the content using text chunking techniques, and then generates text vectors with OpenAI, storing them in a Pinecone database. Users can ask questions through a chat interface, and the system retrieves relevant content based on the vectors to generate answers, while also providing detailed citation sources. This approach effectively addresses the challenges of retrieving information from large documents, significantly enhancing the efficiency and accuracy of information retrieval, and is suitable for various scenarios such as corporate knowledge bases, legal documents, and educational materials.

Workflow Name

Intelligent Document Q&A and Citation Generation Workflow Based on Google Drive Files

Key Features and Highlights

This workflow automates the process of downloading specified files from Google Drive, splitting the file content into smaller chunks using text chunking techniques, generating text embeddings via OpenAI, and storing them in the Pinecone vector database. It enables users to input questions through a chat interface, where the system performs vector-based retrieval to find relevant content chunks and leverages OpenAI’s language model to generate answers. Detailed citation sources are returned alongside responses to ensure accuracy and traceability.

Core Problems Addressed

This solution tackles the challenge of quickly retrieving and accurately answering questions from large documents, particularly unstructured text. By employing vectorization and intelligent retrieval technologies, it enables efficient Q&A over massive document collections with citation references, thereby enhancing trustworthiness.

Application Scenarios

  • Rapid Q&A for enterprise knowledge bases
  • Intelligent retrieval of legal and scientific research documents
  • Instant query resolution for educational and training materials
  • Support services for product manuals and technical documentation
  • Any scenario requiring intelligent Q&A based on large text files

Main Workflow Steps

  1. Manually trigger the workflow to initiate processing
  2. Configure and obtain the target file URL from Google Drive
  3. Download the file and append metadata (filename, extension, URL)
  4. Split the file into fixed-size, overlapping text chunks using a recursive character text splitter
  5. Generate vector embeddings for each text chunk using OpenAI Embeddings
  6. Insert the generated vectors and metadata into the Pinecone vector database
  7. Receive user questions via a chat webhook
  8. Retrieve the most relevant text chunks from Pinecone based on the query
  9. Aggregate retrieved text chunks to prepare contextual input
  10. Call the OpenAI chat model to answer the question based on the context, outputting both the answer and related citation indices
  11. Parse the output format and generate the final answer text with citation information
