About This Workflow
Overview
This n8n workflow is designed to automate the summarization of patent abstracts. It triggers via a Webhook, then uses Langchain nodes to split the text, generate embeddings, and store them in a Supabase vector store. When a query is made (implicitly, this workflow prepares for querying), it uses the vector store and an AI agent to retrieve relevant information and generate a summary. Finally, the results are logged to a Google Sheet.
Key Features
- Trigger automation with a Webhook for incoming patent data.
- Utilize Langchain's Text Splitter to process large patent abstracts.
- Generate AI embeddings using OpenAI for semantic understanding.
- Store and retrieve patent information efficiently using Supabase Vector Store.
- Employ an AI Agent to synthesize information and provide summaries.
- Log automation results to a Google Sheet for tracking.
How To Use
- Set up the n8n workflow by configuring the Webhook to receive patent abstract data.
- Configure the Langchain nodes: specify chunk size and overlap for
Splitter, choose your OpenAI model forEmbeddingsandChat, and define theindexNameforInsert,Query, andTool. - Set up your Supabase account and create a vector store with the specified
indexName. - Authorize n8n to access your OpenAI API and Google Sheets.
- Trigger the Webhook with patent abstract data to initiate the summarization process.
- Configure the Google Sheets node with your
SHEET_IDandsheetNameto log the results.
