     ***************         1st Call for Papers           ***************

 The 21st International Workshop on ONTOLOGY MATCHING (OM-2026)
                    October 25th, 2026, Bari, Italy

collocated with the 25th International Semantic Web Conference ISWC-2026
                  https://om.ontologymatching.org/2026/

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:
1.
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, knowledge graph and web table matching tasks.

2.
To conduct an extensive and rigorous evaluation of ontology matching
and instance matching (link discovery) approaches through
the OAEI (Ontology Alignment Evaluation Initiative) 2026 campaign:
https://oaei.ontologymatching.org/2026/

3.
To examine similarities and differences from other, old, new and emerging,
techniques and usages, such as web table matching or knowledge embeddings.

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;
    Formal foundations and frameworks for matching;
    Novel matching methods, including link prediction, ontology-based 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;
    FAIR (Findable, Accessible, Interoperable and Reusable) alignments;
    Matching for traditional applications (e.g., data science);
    Matching for emerging applications (e.g., web tables, knowledge graphs).
