Automate PDF Text Extraction and Embeddings with Mistral AI
detail.loadingPreview
Streamline your document processing by automatically extracting text from PDF files, chunking it, and generating embeddings using Mistral AI. This workflow empowers you to build intelligent applications with rich text data.
About This Workflow
This n8n workflow automates the complex process of extracting, processing, and analyzing textual data from PDF documents. It begins by fetching a specified PDF file, such as Texas statutes, and then expertly extracts its content. The extracted text is meticulously parsed to isolate and organize sections, titles, and content. Subsequently, the content is intelligently chunked into manageable sizes, preparing it for advanced natural language processing. Finally, this processed text is transformed into high-quality embeddings using Mistral AI's powerful models, making it ready for applications like semantic search, RAG systems, and intelligent data analysis. This robust solution significantly reduces manual effort and unlocks the potential of your unstructured PDF data.
Key Features
- Automated PDF Text Extraction: Reliably extract text from PDF documents, preserving structure and metadata.
- Intelligent Content Parsing: Automatically identifies and separates sections, titles, and content from complex PDFs.
- Scalable Text Chunking: Divides large documents into smaller, manageable chunks for efficient processing.
- Mistral AI Embeddings Generation: Leverages Mistral AI's state-of-the-art models to create powerful text embeddings.
- Customizable Metadata: Attaches relevant metadata (chapter, section, title) to each processed content piece.
How To Use
- Trigger the Workflow: Initiate the workflow by clicking the 'Test workflow' button.
- Fetch PDF: The workflow automatically downloads a PDF file from a specified URL (e.g., Texas statutes).
- Extract & Parse Text: The PDF content is extracted, and the text is parsed to identify sections, titles, and content.
- Chunk Content: The extracted content is divided into smaller chunks suitable for embedding.
- Generate Embeddings: The 'Embeddings Mistral Cloud' node processes the text chunks to generate embeddings using your Mistral Cloud credentials.
- Load Data: The 'Default Data Loader' node prepares the data with associated metadata for further processing or storage.
- Optional: Execute Sub-Workflow: The 'Execute Workflow Trigger' can be used to pass processed data to another n8n workflow for further actions.
