SUMMARY:School Seminar Series
DESCRIPTION:Dr. Ernesto Jiménez-Ruiz: Ontology Alignment and the two DL\n\nThe Ontology Matching community has been very active since the first steps of the Semantic Web. The Ontology Alignment Evaluation Initiative (OAEI) has been running annually since 2004. The objective of the OAEI is to perform a systematic evaluation of ontology matching systems to conduct a comparison on the same basis and to enable the reproducibility of the results. The OAEI includes several tracks of different nature and in a diverse set of domains, each of them including one or more matching tasks.\n\n\n\nDespite the amazing evaluation and system development efforts around the Ontology Matching community, there are still several challenges that need to be tackled from both the evaluation and system sides: (i) better connection with real-world needs and user involvement/satisfaction, (ii) discovery of mappings beyond atomic subsumption and equivalence, (iii) combination with machine learning methods, and (iv) awareness of the logical compatibility of the ontologies.\n\n\n\nIn the presentation I will give an overview of the OAEI and the above challenges with a special focus on challenges (iii) and (iv), i.e., the two DLs (Deep Learning and Description Logics). While Deep Learning techniques are introducing elegant solutions with impressive results, the Ontology Matching community should not forget about the need of computing alignment sets that preserve the logical consistency (possibly with only intended entailments) of the integrated ontology (assuming that the alignment is interpreted as a set of Description Logic axioms).\n\nhttps://www.csc.liv.ac.uk/research/seminars/abstract.php?id=1082
