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.

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) 2020 campaign. Besides real-world specific matching tasks, it features the second edition of the Semantic Web Challenge on Tabular Data to Knowledge Graph Matching track.

  • To examine similarities and differences from other, old, new and emerging, techniques and usages, such as process matching, web table matching or knowledge embeddings.

Call for papers



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 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, 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).

Title: Magellan: Toward a System Building Agenda for Semantic Matching

Abstract: Semantic matching finds schema/data elements that refer to the same real-world concepts. Variations of this problem include string matching, entity matching, schema/ontology matching, matching tuples in a table into a knowledge base, and more. In the past five years, we have been building Magellan, a general platform that uses machine learning, big data processing, cloud technologies, and effective user interaction to solve semantic matching problems, focusing on entity matching (EM). Magellan has been deployed at 12 companies and domain science groups, used in high-profile projects (such as a recent effort to save the Amazon rainforest), recently commercialized by GreenBay Technologies, and pushed into EM platforms at Informatica, the world-leading data integration company. In this talk, I will discuss how Magellan is radically different from current EM work. Specifically, I discuss how we focus on "very boring" EM problems, identify the end-to-end process that a user must follow to solve them, then develop semi-automatic tools to support the various steps in the process. I will also discuss why we designed tools to be atomic, highly interoperable, and built into popular ecosystems of data science tools. Finally, I discuss lessons learned, both from Magellan and from my semantic matching work at Informatica. I will also touch on our ongoing effort to extend Magellan to other semantic matching problems, including ontology/schema matching.
