Computer-implemented method, and device for producing a knowledge graph

A device configured to produce a knowledge graph, the knowledge graph including a plurality of triples in the form of <entity A, entity B, relation between entity A and entity B>, the device configured to:

• provide a body of text;
• provide input data for a model, which are defined as a function of the body of text and entities of the knowledge graph;
• determine, using the model, triples, each respective triple of the triples including two entities of the knowledge graph and a relation between the two entities;
• determine an explanation for verifying the respective triple using the model;
• wherein, for the determining of each respective triple and for the determining of the explanation, the device is configured to:
• classify relevant areas of the body of text and discarding areas of the body of text classified as not relevant, and
• derive from the relevant areas of the body of text the relation between a first entity of the two entities and a second entity of the two entities.

A non-transitory machine-readable storage medium on which is stored a computer program for producing a knowledge graph, the knowledge graph including a plurality of triples in the form of <entity A, entity B, relation between entity A and entity B>, the computer program, when executed by a computer, causing the computer to perform the following steps:

• providing a body of text;
• providing input data for a model, which are defined as a function of the body of text and entities of the knowledge graph;
• determining, using the model, triples, each respective triple of the triples including two entities of the knowledge graph and a relation between the two entities;
• determining an explanation for verifying the respective triple using the model;
• wherein, for the determining of each respective triple and for the determining of the explanation, carrying out the following steps:
• classifying relevant areas of the body of text and discarding areas of the body of text classified as not relevant, and
• deriving from the relevant areas of the body of text the relation between a first entity of the two entities and a second entity of the two entities.
