Workshop Description and Motivation
-----------------------------------
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 previous successful organizations (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.

Topics of Interest
------------------
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:
- Ontology evolution
- Ontology versioning
- Ontology merging
- Formal aspects of ontology dynamics
- Foundational issues
- Language extensions for evolution
- Belief revision for ontologies
- Inconsistency/incoherency/invalidity in evolving ontologies
- Change propagation in ontologies and metadata
- Ontologies for dynamic environments
- Dynamic knowledge construction and exploitation
- Engineering evolvable ontologies
- Requirements for ontology evolution
- Case studies in ontology evolution
- Tools to support ontology evolution
- Applications with dynamic ontologies
- Open problems

Workshop Venue and Format
-------------------------
The workshop will take place in Shangai, China, as part of the ISWC-10 conference (http://iswc2010.semanticweb.org/) on November 7 or 8, 2010.
IWOD-10 will be a half-day workshop with regular paper presentations. We will also consider having an invited talk by a prominent scientist working on the field of ontology dynamics.

Submission Guidelines
---------------------
Only electronic submissions will be considered. All submissions should be submitted in pdf format, to http://www.easychair.org/conferences/?conf=iwod10.
Submissions should not exceed 14 pages and should be formatted according to the LNCS Springer format (http://www.springer.com/east/home/computer/lncs?SGWID=5-164-7-72376-0).
The workshop proceedings will both be uploaded to CEUR (http://ceur-ws.org/) and placed on electronic media for distribution at the conference.
