Abstract: A computer-implemented method, system, and computer program product for dynamic access control to a node in a knowledge graph includes: structuring nodes of a knowledge graph into a plurality of hierarchically organized graph layers; assigning, to one or more users, an access right to a first node of the knowledge graph, the access right to the node selected from a plurality of access rights, where different types of users have different access rights; and assigning, to at least one user from the one or more users, an additional access right to a second node of the knowledge graph.

Abstract: A computer-implemented method, system, and computer program product for dynamic access control to a node in a knowledge graph includes: structuring nodes of a knowledge graph into a plurality of hierarchically organized graph layers; assigning, to a user, an access right to a node of the knowledge graph, the access right to the node selected from a plurality of access rights; and changing the access right to the node dynamically, the changing based on at least one of a structure of the knowledge graph, an access history of the user to the node, and a parameter of the user indicative of a condition outside the knowledge graph.
