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 process mapping. Thus, matching ontologies enables the knowledge and data expressed with the matched ontologies to interoperate.

The workshop has three goals:
  • To bring together leaders from academia, industry and user institutions to assess how academic advances are addressing real-world requirements. The workshop will strive to improve academic awareness of industrial and final user needs, and therefore, direct research towards those needs. Simultaneously, the workshop will serve to inform industry and user representatives about existing research efforts that may meet their requirements. The workshop will also investigate how the ontology matching technology is going to evolve, especially with respect to data interlinking, process mapping and web table matching tasks.

  • To conduct an extensive and rigorous evaluation of ontology matching and instance matching (link discovery) approaches through the OAEI (Ontology Alignment Evaluation Initiative) 2018 campaign. Besides real-world specific matching tasks, such as desease-phenotype track supported by the Pistoia Alliance, will introduce web tables instance matching track supported by IBM Research within a specific matching scenario.

  • To examine new uses, similarities and differences from database schema matching, which has received decades of attention but is just beginning to transition to mainstream tools.

Call for papers


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 and replication studies, services, software, methodologies, protocols and measures (not necessarily related to OAEI), and (ii) application of the matching technology in real-life scenarios 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 and open data);
  • Requirements to matching from specific application scenarios (e.g., energy, public sector);
  • Application of matching techniques in real-world scenarios (e.g., with mobile apps);
  • Formal foundations and frameworks for matching;
  • Matching knowledge graphs;
  • Matching and big data;
  • Matching and linked data;
  • Instance matching, data interlinking and relations between them;
  • 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;
  • Reasoning with alignments;
  • Alignment coherence and debugging;
  • Alignment management;
  • Matching for traditional applications (e.g., information integration);
  • Matching for emerging applications (e.g., search, web-services).

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 2018 campaign. Long technical papers should be not longer than 12 pages using the LNCS Style. Short technical papers should be of max. 5 pages. Posters/statements of interest should not exceed 2 pages and should be handled according to the guidelines for technical papers. All contributions should be prepared in PDF format and should be submitted (no later than June 4th, 2018) through the workshop submission site at:

Contributors to the OAEI 2018 campaign have to follow the campaign conditions and schedule at

Important dates:

Contributions will be refereed by the Program Committee. Accepted papers will be published in the workshop proceedings as a volume of CEUR-WS as well as indexed on DBLP. By submitting a paper, the authors accept the CEUR-WS and DBLP publishing rules.

The extended versions of the best technical and OAEI papers of the workshop will be invited to the Knowledge Engineering Review journal. See extended versions of the best contributions of OM-2016 that appeared in Ontology Alignment in Life Sciences special issue at the Journal of Biomedical Semantics.
