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