The WOP workshop series covers issues related to quality in ontology design and ontology design patterns (ODPs) for data and knowledge engineering in Semantic Web. The increased attention to ODPs in recent years through their interaction with emerging trends of the Semantic Web, such as knowledge graphs, can be attributed to their benefit for knowledge engineers and Semantic Web developers. Such benefits come in the form of direct links to requirements, reuse, guidance, and better communication.
The workshop's aim is thus not just: 1) providing an arena for discussing patterns, pattern-based ontologies, systems, datasets, but also 2) broadening the pattern community by developing its own "discourse" for discussing and describing relevant problems and their solutions. A recent development in the Semantic Web community is that the general idea of "pattern" has begun to appear in different but related forms, and at WOP 2025, we intend to continue to include these new trends.
The maturing of Semantic Web technologies cannot be separated from the need for high-quality, reusable ontologies and ontology-based applications. Different types of ODPs have emerged and been proposed to address these quality and reusability issues, and furthermore, methods for devising and discovering new patterns from heterogeneous knowledge sources are being developed and perfected. Patterns offer a number of benefits to ontology engineers and Semantic Web developers, including direct links to their ontology requirements, data and linguistic grounding, as well as support for reuse, guidance, and better communication; the latter is particularly helpful for inexperienced ontology engineers and domain experts who are typically not very familiar with ontology-based modeling. To achieve the inter-personal communication and machine interoperability benefits, patterns need to be shared by a community in order to provide a common language, a discourse, for discussing and understanding the modeling problems. Hence, the aim of this workshop is twofold: (1) to continue providing an arena for proposing and discussing patterns, pattern-based ontologies, systems etc., and (2) to sustain and broaden the pattern community that will further develop its own "language" for discussing and describing modeling problems and their solutions, similarly to what is now the case in software engineering.
We particularly welcome contributions on topics concerning the development of high-quality ontologies in general (with or without the help of ODPs) as well as studies and applications of ODPs for knowledge graph construction and maintenance. In addition, as usual, we also welcome pattern descriptions of all sorts, including patterns geared towards applications in specific domains such as geosciences, life sciences, sustainability, digital humanities, or e-commerce.
The main topics of interest are:
Submissions should be made via the WOP 2025 EasyChair submission page (Link TBC). Papers will be peer-reviewed (single-blind). Detailed instructions will be found at the submission page. Note that pattern descriptions may also need to be submitted to the ontologydesignpatterns.org community portal (details TBC).
Proceedings will be published via CEUR. We will also provide the option of not archiving the submissions on CEUR to the authors.
The WOP Steering committee - the Board of the Association of Ontology Design and Patterns (http://ontologydesignpatterns.org/wiki/ODPA) - consists of:
