knowledge-graph-system vs root-kg

knowledge-graph-system: Kappa Graph is a semantic knowledge graph system designed to extract concepts and relationships from various documents, providing an epistemic layer that measures the reliability and support of claims. It distinguishes itself by offering grounding scores, detecting contradictions, and preserving the full provenance chain to source evidence.; root-kg: ROOT is a local-first knowledge management system that connects your personal notes, meetings, and emails into a queryable intelligence layer. It builds an LLM-powered knowledge graph to provide cited, natural language answers to complex questions, outperforming traditional keyword search.
