About This Workflow
Overview
This workflow automates the process of ingesting documents from Google Drive, performing context-aware chunking, generating embeddings with Google Gemini, and storing these embeddings in Pinecone. This is designed for Retrieval Augmented Generation (RAG) systems, aiming to improve the accuracy and relevance of retrieved information by embedding text chunks along with their contextual surrounding.
Key Features
- Document Ingestion: Downloads documents directly from Google Drive.
- Contextual Chunking: Splits documents into sections and generates short, succinct context for each chunk.
- Embedding Generation: Utilizes Google Gemini for creating high-quality text embeddings.
- Vector Storage: Stores the embeddings and their associated context in a Pinecone vector database.
- RAG Optimization: Enhances RAG performance by including context in the embedding process.
Key Features
- Downloads documents from Google Drive.
- Splits document text into sections using a custom delimiter.
- Generates context for each text chunk using an AI agent.
- Concatenates chunk text with its generated context.
- Creates embeddings using Google Gemini.
- Inserts embeddings into a Pinecone vector store.
How To Use
- Configure Credentials: Set up Google Drive OAuth2 API and Pinecone API credentials in n8n.
- Set Google Drive File ID: In the 'Get Document From Google Drive' node, specify the
fileIdof the document you want to process. - Define Section Separator: Ensure the
split_textvariable in the 'Split Document Text Into Sections' code node accurately reflects the separator used in your document to denote section breaks. - Configure Pinecone Index: In the 'Pinecone Vector Store' node, specify your Pinecone index name.
- Customize Gemini Model: In the 'Embeddings Google Gemini' node, you can choose a different Google Gemini model if needed.
- Run the Workflow: Execute the workflow. The processed chunks and their embeddings will be stored in your Pinecone index.
