Abstract
A method of updating a server knowledge graph, is performed by a server and includes obtaining a server knowledge graph of the server, and obtaining a plurality of device knowledge graphs by receiving a device knowledge graph from each of a plurality of devices. The method further includes generating a knowledge graph for server knowledge graph extension, based on the obtained plurality of device knowledge graphs, and updating the obtained server knowledge graph, using the generated knowledge graph for server knowledge graph extension.
Claims20
A method of updating a server knowledge graph, the method being performed by a server and comprising:
- obtaining a server knowledge graph of the server;
- obtaining a plurality of device knowledge graphs by receiving a device knowledge graph from each of a plurality of devices, the device knowledge graph including nodes corresponding to concepts, determined from raw data or knowledge triples by using at least one of a probabilistic matching model, a distance-based model, or declarative matching rules and constraints, and edges representing relationships between the concepts, wherein the nodes and the edges of the device knowledge graph of a device represent a series of operations that are executed in the device;
- generating a knowledge graph for server knowledge graph extension, based on comparison between nodes and edges in the obtained plurality of device knowledge graphs;
- and
- updating the obtained server knowledge graph, using the generated knowledge graph for server knowledge graph extension.
A server for updating a server knowledge graph, the server comprising:
- a storage storing at least one instruction;
- and
- a processor configured to execute the at least one instruction to:
- obtain a server knowledge graph of the server;
- obtain a plurality of device knowledge graphs by receiving a device knowledge graph from each of a plurality of devices, the device knowledge graph including nodes corresponding to concepts, determined from raw data or knowledge triples by using at least one of a probabilistic matching model, a distance-based model, or declarative matching rules and constraints, and edges representing relationships between the concepts, wherein the nodes and the edges of the device knowledge graph of a device represent a series of operations that are executed in the device;
- generate a knowledge graph for server knowledge graph extension, based on comparison between nodes and edges in the obtained plurality of device knowledge graphs;
- and
- update the obtained server knowledge graph, using the generated knowledge graph for server knowledge graph extension.
