OntoEA: Ontology-guided Entity Alignment via Joint Knowledge Graph Embedding
This addresses the challenge of entity alignment in knowledge graphs for applications like data integration, though it appears incremental by building on existing embedding methods.
The paper tackled the problem of aligning entities across knowledge graphs by incorporating ontological schema, which previous methods ignored, and achieved state-of-the-art performance on seven benchmarks.
Semantic embedding has been widely investigated for aligning knowledge graph (KG) entities. Current methods have explored and utilized the graph structure, the entity names and attributes, but ignore the ontology (or ontological schema) which contains critical meta information such as classes and their membership relationships with entities. In this paper, we propose an ontology-guided entity alignment method named OntoEA, where both KGs and their ontologies are jointly embedded, and the class hierarchy and the class disjointness are utilized to avoid false mappings. Extensive experiments on seven public and industrial benchmarks have demonstrated the state-of-the-art performance of OntoEA and the effectiveness of the ontologies.
