Abstract

A method and a related system for controlling user access to a target node in a knowledge graph may be provided. The method comprises defining a knowledge graph structure limitation for a user, defining a node type depending on the number of edges connecting to the node, determining a condition for an access to the target node, based on the knowledge graph structure limitation relative to the start node and the node type of the target node, upon the user attempting, coming from a start node, to access the target node in the knowledge graph, and granting access to the target node based on the determination.
