InterOntology08 – Interdiciplinary Ontology Forum in Japan

InterOntology08 – Interdiciplinary Ontology Forum in Japan

This conference was held at the Keio University in Tokyo. Prof. Hideaki Takeda gave his invited talk titled “Ontology for People — Vagueness and multiplicity”. He talked about how conceptualizations are naturally vague and essentially lead to multiple concept definitions depending on the user’s perspective. He introduced my work, StYLiD, as a system to consider with such vagueness and multiplicity ๐Ÿ™‚

OntoBlog: Linking Ontology and Blogs

I presented this paper in the Semantic Authoring, Annotation and Knowledge Markup Workshop (SAAKM 2007) co-located with the 4th International Conference on Knowledge Capture (K-Cap 2007), Whistler, British Columbia, Canada. It was an interesting workshop followed up by enthusiastic discussions.

Online proceedings is available here.ย  You can download my paper here and these 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.

Using Data-Extraction Ontologies to Foster Automating Semantic Annotation

Using Data-Extraction Ontologies to Foster Automating Semantic Annotation
Semantic annotation adds formal metadata to web pages to link web data with ontology concepts. Automated semantic annotation is a primary way of enabling the semantic web. A main drawback of existing automated semantic annotation approaches is that they need a post-extraction mapping between extraction categories and ontology concepts. This mapping requirement usually needs human intervention, which decreases automation. Our approach uses data-extraction ontologies to avoid this problem. To automate semantic annotation, the new approach uses an ontology-based data recognizer that fosters automated semantic annotation, optimizes the system performance, provides support for ontology assembly, and is compatible with semantic web standards.
