Ontologies constitute one of the main pillars of the Semantic Web and of semantic applications. As ontologies model dynamic environments (e.g., e-science ontologies), they are often subject to change. The support for dynamicity is one of the core ontology management problems and has many facets, being dealt with in different fields, like ontology evolution, ontology versioning and others.
Following the previous successful editions (as part of ESWC-07, ISWC-08 and ISWC-09), IWOD has established itself as the core annual event to discuss advances in the broad area of ontology dynamics, and to track recent work directly or indirectly related to the problem of evolving ontologies. The goal of the 4th International Workshop on Ontology Dynamics (IWOD-10) is to bring together researchers and students working on the fields of ontology evolution, revision, merging and versioning, as well as people from the industry conducting activities (applications, case studies) that involve the dynamic aspects of ontologies. Our aim is to trigger discussions and allow interested researchers, students and practitioners to present and discuss recent advances related to these fields. Both theoretical research works as well as works describing implemented systems or tools are welcome.
Since recently, we witness the development of new, more accessible semantic technologies, as well as the emergence of new needs from semantic applications and a rising awareness of the potential of ontologies. As a result, more and more people and organisations have started to develop ontologies and applications of ontologies. However, ontologies, just like any structure holding knowledge, need to be updated. There are several reasons why an ontology should change: changes could be initiated because of a change in the world being modeled; the users’ needs may change, requiring a different conceptualization; knowledge previously unknown, classified or otherwise unavailable may become known; or a design flaw may have been noticed in the original conceptualization. In addition, ontologies often model dynamic environments, as in the case of e-science ontologies (e.g., in bioinformatics, the Gene Ontology changes daily).
In such cases, the representation of our knowledge in the ontology should be modified so as to form a more accurate or adequate conceptualization of the domain. Such a modification presents several difficulties from both the practical and the theoretical point of view, raising a variety of research questions and development issues, such as how to support the developers of ontologies in maintaining up-to-date, adequate conceptualizations; how to detect the need for evolution; how to facilitate the integration of new knowledge in ontologies; how to validate and evaluate the impact of the evolution of an ontology; how to handle evolutions triggered from multiple sources and collaborative updates; how to determine the optimum update result; what properties should such a result satisfy; and how to keep track of (possibly concurrent) versions of ontologies and ensure the delivery of up-to-date and valid knowledge.
IWOD-10 intends to be a forum where these questions are discussed. This workshop will bring together researchers, students and practitioners interested in the field of ontology dynamics, in order to discuss and analyze important characteristics, open research issues and recent research developments in the area. We are interested in advances related to the fields of ontology evolution, revision, merging and versioning, as well as to applications and case studies that involve the dynamic aspects of ontologies.
We encourage submissions on all topics related to ontology dynamics, including original theoretical work on the issues involved directly or indirectly with change as well as applications or implemented systems related to such issues. We are particularly (but not exclusively) interested in the following topics:
Anyone (from academia or industry) working on ontology evolution or related fields; people designing, supporting, or using ontologies that are subject to change; software engineers of ontology management/versioning/evolution tools.
