The Sixteenth International Workshop on Ontology Matching

Ontology matching is a key interoperability enabler for the Semantic Web, as well as a useful technique in some classical data integration tasks dealing with the semantic heterogeneity problem. It takes ontologies as input and determines as output an alignment, that is, a set of correspondences between the semantically related entities of those ontologies. These correspondences can be used for various tasks, such as ontology merging, data interlinking, query answering or navigation over knowledge graphs. Thus, matching ontologies enables the knowledge and data expressed with the matched ontologies to interoperate.

Audience:

The workshop encourages participation from academia, industry and user institutions with the emphasis on theoretical and practical aspects of ontology matching. On the one side, we expect representatives from industry and user organizations to present business cases and their requirements for ontology matching. On the other side, we expect academic participants to present their approaches vis-a-vis those requirements. The workshop provides an informal setting for researchers and practitioners from different related initiatives to meet and benefit from each other's work and requirements.

This year, in sync with the main conference, we encourage submissions specifically devoted to: (i) datasets, benchmarks, software tools/services, APIs, methodologies, protocols and metrics (not necessarily related to OAEI), and (ii) application of ontology and instance matching technology in a specific domain and assessment of its usefulness to the final users.

Topics of interest include but are not limited to:

• Business and use cases for matching (e.g., big, open, closed data)
• Requirements to matching from specific application scenarios (e.g., public sector, homeland security)
• Application of matching techniques in real-world scenarios (e.g., in cloud, with mobile apps)
• Formal foundations and frameworks for matching
• Novel matching methods, including link prediction, ontology-based data access
• Matching and knowledge graphs
• Matching and deep learning
• Matching and embeddings
• Matching and big data
• Matching and linked data
• Instance matching, data interlinking and relations between them
• Privacy-aware matching
• Process model matching
• Large-scale and efficient matching techniques
• Matcher selection, combination and tuning
• User involvement (including both technical and organizational aspects)
• Explanations in matching
• Social and collaborative matching
• Uncertainty in matching
• Expressive alignments
• Reasoning with alignments
• Alignment coherence and debugging
• Alignment management
• Matching for traditional applications (e.g., data science)
• Matching for emerging applications (e.g., web tables, knowledge graphs)

Contributions to the workshop can be made in terms of technical papers and posters/statements of interest addressing different issues of ontology matching as well as participating in the OAEI 2021 campaign. Long technical papers should be of max. 12 pages. Short technical papers should be of max. 5 pages. Posters/statements of interest should not exceed 2 pages. All contributions have to be prepared using the LNCS Style and should be submitted in PDF format (no later than August 9th, 2021) through the workshop submission site at:
