Ontology matching is a key interoperability enabler for the Semantic Web, as well as a useful tactic in some classical data integration tasks dealing with the semantic heterogeneity problem. 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, data translation, query answering or navigation on the web of data. 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) 2012 campaign. The particular focus of this year's OAEI campaign is on real-world specific matching tasks involving, e.g., linked open data and biomedical ontologies. 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 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) repeatable evaluations of the approaches proposed (not necessarily within 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., open government data);
  • Requirements to matching from specific domains;
  • Application of matching techniques in real-world scenarios;
  • Formal foundations and frameworks for matching;
  • Matching patterns;
  • Instance matching and data interlinking;
  • Large-scale matching evaluation;
  • Performance of matching techniques;
  • Matcher selection and self-configuration;
  • 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 emerging applications (e.g., linked data, search).

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 2012 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 July 31st, 2012) through the workshop submission site at:

   Details on panel "What's the user to do? Ontology matching and the real world"
  • What are the tools that are available today? What is their relationships with the mapping algorithms that the researchers are developing?
  • What kind of support should ontology mapping user-facing tools provide?
  • What is the quality of mappings that domain experts produce?
  • Should domain experts be the ones performing ontology matching or are they so bad at it that all the mapping should be automatic anyway?
  • How do we factor in the interactive tools into the formal evaluation such as OAEI?
  • Are the ontologies mapped in OAEI representative of the ontologies that need to be mapping in the real world, or representative of the ontologies that the tool builders like to map?
