StYLiD: Social Information Sharing with Free Creation of Structured Linked Data

StYLiD: Social Information Sharing with Free Creation of Structured Linked Data

I presented this paper about StYLiD in the Social Web and Knowledge Management Workshop (SWKM 2008), April 22nd, co-located at the 17th World Wide Web Conference WWW2008, Beijing, China. It was a half-day workshop with only 6 selected papers. The session was interesting and very relevant to my area of research.  This was my first time to attend the WWW conference. Quite an honor to be in such a great conference 😉

Here is my paper and here are my slides.

Understanding ontology evolution: A change detection approach

ScienceDirect – Web Semantics: Science, Services and Agents on the World Wide Web : Understanding ontology evolution: A change detection approach

In this article, we propose a change detection approach in the context of an ontology evolution framework for OWL DL ontologies. The framework allows ontology engineers to request and apply changes to the ontology they manage. Furthermore, the framework assures that the ontology and its depending artifacts remain consistent after changes have been applied. Innovative is that the framework includes a change detection mechanism that allows generating automatically a detailed overview of changes that have occurred based on a set of change definitions. In addition, different users (such as maintainers of depending artifacts) may have their own set of change definitions, which results into different overviews of the changes, each providing a different view on how the ontology has been changed. Using these change definitions, also different levels of abstraction are supported. Both features will enhance the understanding of the evolution of an ontology for different users.
