Multi-view Knowledge Graph Embedding for Entity Alignment
This addresses the problem of improving accuracy and robustness in entity alignment for knowledge graph integration, though it appears incremental by combining existing features more effectively.
The paper tackles entity alignment between knowledge graphs by proposing a framework that unifies multiple views (entity names, relations, attributes) with cross-KG inference, significantly outperforming state-of-the-art methods.
We study the problem of embedding-based entity alignment between knowledge graphs (KGs). Previous works mainly focus on the relational structure of entities. Some further incorporate another type of features, such as attributes, for refinement. However, a vast of entity features are still unexplored or not equally treated together, which impairs the accuracy and robustness of embedding-based entity alignment. In this paper, we propose a novel framework that unifies multiple views of entities to learn embeddings for entity alignment. Specifically, we embed entities based on the views of entity names, relations and attributes, with several combination strategies. Furthermore, we design some cross-KG inference methods to enhance the alignment between two KGs. Our experiments on real-world datasets show that the proposed framework significantly outperforms the state-of-the-art embedding-based entity alignment methods. The selected views, cross-KG inference and combination strategies all contribute to the performance improvement.
