Abstract
There is provided a method and a system for evaluating a relevance score of a given subset of nodes in a knowledge graph (KG) for purpose of link prediction. An ontology used to generate the KG is obtained and clustered to obtain a set of ontology clusters. A set of vectors having been generated by using an embedding model on the KG is obtained and clustered to obtain a set of vector clusters. Training subgraphs are generated based on the set of ontology clusters and the set of vector clusters by removing subsets of nodes from the KG. Respective prediction models are trained on each training subgraph and ranked based on their link predictions. The relevance score of each removed subset of nodes is determined based on the ranked models. A given subset of nodes is provided as a potential explanation based on the relevance score.
