Ontology matching is a key interoperability enabler for the Semantic Web, as well as a useful tactic in some classical data integration tasks. It takes the 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 and data translation. Thus, matching ontologies enables the knowledge and data expressed in 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.

  • To conduct an extensive and rigorous evaluation of ontology matching approaches through the OAEI (Ontology Alignment Evaluation Initiative) 2009 campaign. This year's OAEI campaign introduces two new tracks about oriented alignments and about instance matching (a timely topic for the linked data community). Therefore, the ontology matching evaluation initiative itself will provide a solid ground for discussion of how well the current approaches are meeting business needs.

  • To examine 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 its 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.

Topics of interest include but are not limited to:

  • Business cases for matching;
  • Requirements to matching from specific domains;
  • Application of matching techniques in real-world scenarios;
  • Formal foundations and frameworks for ontology matching;
  • Large-scale ontology matching evaluation;
  • Performance of matching techniques;
  • Matcher selection and self-configuration;
  • Uncertainty in ontology matching;
  • User involvement (including both technical and organizational aspects);
  • Explanations in matching;
  • Social and collaborative matching;
  • Alignment management;
  • Reasoning with alignments;
  • Matching for traditional applications (e.g., information integration);
  • Matching for dynamic applications (e.g., peer-to-peer, agents, 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 2009 campaign. Technical papers should be not longer than 12 pages using the LNCS Style. 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 August 11, 2009) through the workshop submission site at:
