Build an LLM-powered knowledge extraction framework in Python. Define 8 strongly-typed Auto-Types — from AutoList to AutoGraph, AutoHypergraph, and AutoSpatioTemporalGraph. Layer extraction engines (GraphRAG, LightRAG, KG-Gen, Hyper-RAG) to turn unstructured text into structured knowledge using OpenAI models. Add declarative YAML templates across 6 domains (Finance, Medical, Legal) for zero-code extraction. Expose a CLI (parse, search, feed) and a Python API.
Foire aux questions
LLM knowledge extraction is the process of using large language models to transform unstructured text into structured, actionable data formats. In this Python-based framework, we utilize OpenAI models and specialized extraction engines like GraphRAG and LightRAG. By defining strongly-typed Auto-Types, the system can automatically identify entities and relationships, organizing them into complex structures such as AutoGraphs or AutoHypergraphs for better data retrieval and analysis.
Auto-Types are strongly-typed schemas used to define the structure of extracted knowledge. This framework supports eight distinct types, ranging from simple AutoLists to complex AutoGraphs, AutoHypergraphs, and AutoSpatioTemporalGraphs. These types allow the framework to map unstructured text into specific mathematical and relational models, ensuring that the output data is consistent, validated, and ready for use in graph-based databases or downstream analytical applications.
GraphRAG and Hyper-RAG are advanced extraction engines that layer on top of standard LLMs to improve the depth of structured data. While traditional RAG focuses on simple text retrieval, GraphRAG builds relational maps between entities, and Hyper-RAG handles higher-order relationships. By integrating these with LightRAG and KG-Gen, the framework can process complex documents in domains like Finance, Medical, and Legal, turning raw text into high-fidelity knowledge graphs.
Yes, the framework includes declarative YAML templates designed for zero-code extraction across six specialized domains, including Finance, Medical, and Legal. These templates allow users to define extraction rules without writing Python code. For developers, the system also exposes a robust CLI with commands like parse, search, and feed, as well as a comprehensive Python API for integrating the knowledge extraction pipeline into existing software stacks.
