Core Features

Knowledge Structures

Supports 8 knowledge structures ranging from simple Collections to complex Knowledge Graphs, Hypergraphs, and Spatio-Temporal Graphs, allowing for diverse data representations.

Source: README
Extraction Engines

Incorporates 10+ extraction engines such as GraphRAG, LightRAG, and KG-Gen, providing a robust set of tools for knowledge extraction.

Source: README
YAML Templates

Includes 80+ YAML templates for various domains like Finance, Legal, and Medical, enabling zero-code extraction without the need for custom development.

Source: README
Incremental Evolution

Supports incremental evolution of knowledge bases by allowing the addition of new documents to expand and refine existing knowledge.

Source: README

Architecture

Hyper-Extract follows a three-layer architecture: Auto-Types (strongly-typed data structures), Methods (extraction algorithms), and Templates (presets for different domains). This modular approach allows for flexibility and scalability.
