FLORA: Unsupervised Knowledge Graph Alignment by Fuzzy Logic

graph-neural-networks › knowledge-graphs
📄 Abstract

Abstract: Knowledge graph alignment is the task of matching equivalent entities (that is, instances and classes) and relations across two knowledge graphs. Most existing methods focus on pure entity-level alignment, computing the similarity of entities in some embedding space. They lack interpretable reasoning and need training data to work. In this paper, we propose FLORA, a simple yet effective method that (1) is unsupervised, i.e., does not require training data, (2) provides a holistic alignment for entities and relations iteratively, (3) is based on fuzzy logic and thus delivers interpretable results, (4) provably converges, (5) allows dangling entities, i.e., entities without a counterpart in the other KG, and (6) achieves state-of-the-art results on major benchmarks.

Key Contributions

Proposes FLORA, an unsupervised method for knowledge graph alignment based on fuzzy logic. FLORA provides a holistic, interpretable alignment for entities and relations, guarantees convergence, handles dangling entities, and achieves state-of-the-art results without requiring training data.

Business Value

Facilitates the integration of disparate knowledge sources, enabling richer data analysis, improved search capabilities, and more robust AI systems by creating unified knowledge representations.
