About This Workflow
Overview
This n8n workflow is designed to automate the process of summarizing breaking news articles. It leverages the power of Langchain for AI-driven text processing and Weaviate as a vector database for efficient information retrieval. The workflow starts by receiving news content via a webhook. This content is then split into manageable chunks using the Splitter node. These chunks are embedded into vector representations using Embeddings (HuggingFace) and stored in Weaviate via the Insert node. When a request to summarize is made, the Query node retrieves relevant information from Weaviate, which is then processed by an Agent node, utilizing a Chat model and Memory to generate a concise summary. Finally, the summary is logged to a Google Sheet using the Sheet node.
Key Features
- Real-time breaking news ingestion via Webhook.
- Advanced text chunking and embedding for AI processing.
- Efficient storage and retrieval of news content using Weaviate.
- AI-powered summarization driven by a Langchain Agent.
- Conversation memory to maintain context during summarization.
- Logging of summaries to Google Sheets for record-keeping.
How To Use
- Set up the n8n webhook to receive breaking news content.
- Configure the
Splitternode with appropriate chunk sizes and overlaps. - Ensure your HuggingFace API credentials are set for the
Embeddingsnode. - Set up your Weaviate instance and provide the API credentials for the
InsertandQuerynodes. Configure theindexNametobreaking_news_summarizer. - Configure your OpenAI API credentials for the
Chatnode. - Customize the
Agentnode's prompt to define the desired summarization style. - Set up your Google Sheets credentials and ensure the
documentIdandsheetNamein theSheetnode are correct for logging. - Trigger the webhook with breaking news content to initiate the summarization process.
