A Complex Alignment Benchmark: GeoLink Dataset

Author(s): Lu Zhou, Michelle Cheatham, Adila Krisnadhi

Abstract: Ontology alignment has been studied for over a decade, and over that time many alignment systems and methods have been developed by researchers in order to find simple 1-to-1 equivalence matches be- tween two ontologies. However, very few alignment systems focus on find- ing complex correspondences. One reason for this limitation may be that there is no widely accepted alignment benchmark that contains such complex relationships. In this paper, we propose a real-world dataset from the GeoLink project as a potential complex alignment benchmark. The dataset consists of two ontologies, the GeoLink Base Ontology (GBO) and the GeoLink Modular Ontology (GMO), that were developed in consultation with numerous domain experts. The manually created alignment between these two ontologies includes 1:1, 1:n, and m:n equivalence and subsumption correspondences. The reference alignment for this benchmark is available in both EDOAL and rules syntax.
