SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Knowledge graphs often grow large and unwieldy, making extraction, maintenance, and query answering expensive. This Skill offers end-to-end support for entity and relationship extraction, ontology-driven schema application, and compression techniques that preserve query semantics while dramatically reducing size. It enables domain-specific modeling and multi-scale representations via metagraphs and category-theoretic quotients.

Core Features & Use Cases

  • Structured entity extraction with provenance and confidence scores
  • Relationship mapping across domain schemas (core_ontology.md, coding_domain.md, categorical_ontology.md)
  • Structural equivalence analysis and k-bisimulation-based compression
  • Categorical quotient construction and metagraph hierarchical modeling
  • Topology metrics, quality validation, and query-preservation verification for scalable knowledge graphs

Quick Start

Run a sample compression workflow on a knowledge graph to see end-to-end extraction, validation, and query-preserving compression in action.

FAQPage Schema
How do I compress a large knowledge graph without losing query accuracy?

Knowledge graph compression uses automorphism-based reduction and k-bisimulation summarization to shrink graph size while preserving query semantics. Categorical quotient constructions maintain formal guarantees for query answering on the compressed structure.

What is k-bisimulation summarization for scalable graph analytics?

K-bisimulation summarization groups structurally equivalent nodes in a knowledge graph to produce a smaller quotient graph. This technique retains query preservation capabilities and topology metrics while dramatically reducing the overall graph scale.

How do I extract entities and relationships from text for ontology engineering?

Structured entity extraction maps relationships across domain schemas and applies confidence scoring with provenance tracking. This process builds ontology-driven knowledge graphs by linking extracted text entities to categorical ontology definitions.

When do I need metagraph hierarchical modeling for knowledge graphs?

Metagraph hierarchical modeling is needed when managing multi-scale representations in large knowledge graphs. It enables domain-specific schema application and categorical quotient construction to maintain topology metrics across different abstraction layers.

Does graph compression work with domain-specific schemas and provenance tracking?

Graph compression operates directly on domain-specific schemas while maintaining provenance and confidence scores for extracted entities. Quality validation and query-preservation verification ensure the compressed graph retains structural fidelity and domain ontology rules.

What are the limitations of automorphism-based compression for knowledge graphs?

Automorphism-based compression effectiveness depends on the structural redundancy within the knowledge graph; highly irregular graphs yield minimal size reduction. Quotient constructions and skeleton-based representations must still pass query-preservation verification to ensure valid analytics.
