RAGCTL is a command-line tool that simplifies document processing for RAG applications. With features like universal document loading, advanced OCR, and intelligent chunking, it handles ingestion and preparation tasks, allowing developers to focus on building effective RAG systems without the hassle of manual processing.
RAG Studio (ragctl) is a powerful command-line tool designed for efficient document processing tailored for Retrieval-Augmented Generation (RAG) systems. It simplifies document ingestion, utilizes advanced Optical Character Recognition (OCR), and performs intelligent chunking, all from the command line.
Key Features
- Universal Document Loading: Supports multiple formats including PDF, DOCX, ODT, TXT, HTML, Markdown, and various image types (JPEG, PNG).
- Advanced OCR Capabilities: Operates with a cascade of OCR engines — EasyOCR, PaddleOCR, and pytesseract — ensuring flexibility and accuracy in text extraction.
- Intelligent Chunking: Utilizes LangChain's recursive text splitter for context-aware chunking, offering different strategies such as semantic, sentence, and fixed token-based splitting.
- Production-Ready Processing: Facilitates batch processing with built-in retry mechanisms and customizable error handling modes, enabling robust workflows.
- Flexible Export Options: Enables output in multiple formats including JSON, JSONL, and CSV, as well as direct ingestion into Qdrant vector stores, ensuring compatibility with various data management systems.
Technical Specifications
Document Processing
- Supported Formats: Handles diverse document types, adapting to content seamlessly.
- OCR Engine Fallbacks: Automatically selects the most effective OCR engine while allowing for manual adjustments.
- Multilingual Support: Supports various languages ensuring global usability.
Chunking Strategies
- Semantic Chunking: Default mode focuses on preserving meaning, with options for sentence and token-based splitting.
- Metadata-Rich Output: Provides comprehensive metadata for each text chunk, including source file and timestamp information, enabling better tracking and usage optimization.
Batch Processing
- Error Handling Options: Includes several modes such as interactive, automatic continuation, auto-stop, and skip functionalities to manage processing efficiently.
- History Tracking: Maintains a detailed history of all operations for future reference and troubleshooting.
Configuration and Customization
- Hierarchical Configuration System: Allows settings to be defined via command line, environment variables, or YAML files, providing convenient management of individual preferences.
Usage Examples
- Single Document Processing:
ragctl chunk document.pdf --show - Batch Processing:
ragctl batch ./documents --output ./chunks/ - Retrying Failed Cases:
ragctl retry - Evaluating Chunk Quality:
ragctl eval document.pdf --strategies semantic sentence --metrics coverage overlap
