The minimum number of connections you'd need to cut before the graph falls apart. A measure of how robust the structure is. Also kg — the unit of mass. Because knowledge here has weight. Grounding scores measure how heavy an idea is: well-evidenced claims carry more than thin ones. Contested concepts weigh differently than unchallenged ones. Quick Start Install Client Tools The kg CLI, MCP server (for AI assistants), and optional FUSE filesystem: Or just the CLI: npm install -g @aaronsb/kg-cli Deploy the Platform Run your own knowledge graph backend: Or from source: See Quick Start Guide for details. See It In Action Interactive graph exploration with smart search, concept clustering, and relationship visualization Command-line search returns concepts with source images rendered inline via chafa t-SNE embedding landscape with auto-detected clusters, named by topic via TF-IDF What You Can Do Ingest documents — PDFs, markdown, images, text. The system extracts concepts, relationships, and evidence automatically. Search by meaning — \"economic downturn\" finds content about recessions, crashes, and crises even if those exact words aren't used. Explore connections — Find paths between concepts. See how ideas relate across documents. Check confidence — Every result includes grounding sco","default_branch":null,"files":null,"tree":[],"storefront":"/r/aaronsb","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/aaronsb/knowledge-graph-system/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
