Abstract

The present disclosure describes methods and systems for generating an explanation for a prediction based on a knowledge graph. The method includes receiving a target triple and a knowledge graph including a set of structured data; converting the knowledge graph to an embeddings space and outputting a plausibility prediction for the target triple; sampling a set of neighbors of elements of the target triple in the embeddings space; obtaining a set of example triples based on the set of neighbors according to the target triple; obtaining a prototype graph based on the set of the example triples according to the target triple; generating an explanation graph based on the prototype graph, the set of example triples, and the target triple; and generating an explanation for the plausibility prediction based on the explanation graph.
