         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.

       The goal of the 4th International Workshop on Ontology Dynamics (IWOD-10)
was 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 was to trigger discussions and allow interested researchers, students
and practitioners to present and discuss recent advances related to these fields.

       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 4th International Workshop of
Ontology Dynamics was hosted as a half-day workshop in the ISWC-10, held in Shangai,
China, on November 8, 2010.

        We would like to thank our invited speaker, Dr. Zhisheng Huang, who was kind
enough to give a keynote talk titled: “Interleaving Reasoning and Selection with
Semantic Data”. In addition, we would like to thank the workshop’s Steering Committee,
Mathieu d’Aquin, Grigoris Antoniou, Jeff Pan and Dimitris Plexousakis for their help in
making this workshop a reality, the Program Committee members and external reviewers
for their excellent reviews which ensured that the best possible material was presented in
the workshop and appears in these proceedings, and, of course, the organizers of the
ISWC-10 conference for supporting this workshop. Last but not least, we would like to
thank the authors of all submitted papers, as well as all the participants of the workshop
for their interest in IWOD-10.
