About my research

Statement & focus

A key aspect of my research is focusing on supporting an ordinary user's perspectives on the emerging Semantic Web technology (SWT). One substantial part of my personal research interest concerns the aspects of interpreting and interacting with ontologies; a research line, novel in the field of ontology engineering, I developed in the context of NeOn project, and previously in the AKT: Advanced Knowledge Technologies, in the KnowledgeWeb project, and generally in my Magpie research and development.

The second substantial item of my research agenda concerns designing robust infrastructures for semantically and socially enriched web applications and tasks (such as semantic web navigation or contextual visualization) that are usable by and accessible to ordinary users. This latter line of research has been particularly strong in my Magpie Semantic Web Browser, but also in the climateprediction.net and BuddySpace Instant Messaging projects.
