Abstract

This article introduces an innovative method for rewriting SPARQL queries in the context of complex ontology alignment by leveraging hierarchical relations such as subClassOf and subPropertyOf. The method relies on generalization and specialization links between concepts to retrieve relevant results, even when strict equivalences are missing. In addition, the use of natural language, assisted by the GPT-4 model, helps address the syntactic complexity of SPARQL and facilitates interaction with ontologies. Unlike existing approaches that focus mainly on simple (s: s) or semi-complex (s: c) alignments based on equivalence between source and target entities, our method reinforces semantic matching by explicitly incorporating subsumption relations. It also integrates complex (c: c) correspondences, which are often overlooked in the literature, thereby improving both query coverage and accuracy. Experiments conducted on ontology datasets in the conference domain confirm the method’s ability to capture a wide range of hierarchical relations. While the method is designed to be generic, further evaluations on large-scale ontologies are required to assess its robustness and generalizability.
