Knowledge Graph Schema Definition And Validation With Configurable Entity Relationship Types

via “knowledge graph construction with entity extraction and community detection”

SoTA production-ready AI retrieval system. Agentic Retrieval-Augmented Generation (RAG) with a RESTful API.

Unique: Integrates LLM-based entity extraction with networkx community detection in a single pipeline, enabling automatic semantic clustering without manual ontology definition. Graph is stored in PostgreSQL alongside document vectors, allowing hybrid queries that combine vector search with graph traversal.

vs others: More flexible than Neo4j's built-in extraction because entity types and relationships are configurable via LLM prompts; more integrated than standalone knowledge graph tools because graph is queried alongside RAG retrieval in the same API call.
