@ector/concept-network

Concept Network is weighted directed graph, in which activation values can be propagated, using @ector/state.

Usage

const conceptNetwork = require('@ector/concept-network');

let cn = conceptNetwork.addNode({}, 'node1');
cn = conceptNetwork.addNode(cn, 'node2');

cn = conceptNetwork.addLink(cn, 'node1', 'node2');
// {
//   node: [ { label: 'node1', occ: 1 }, { label: 'node2', occ: 1 } ],
//   link: [ { from: 0, to: 1, coOcc: 1 } ]
// }
