The focus of my research is Semantic Web data management, in particular:
- Semantic data integration. This is a complex problem which arises when combining semantic data from different repositories and involves several more specific problems such as instance coreference resolution, inconsistency resolution, and ontology matching. To facilitate the semantic data fusion process, we developed the KnoFuss semantic data fusion architecture. Light-weight data fusion techniques were included into the PowerAqua ontology-based question-answering system.
- Ontology engineering. My work in the SmartProducts project includes building ontologies modelling information needed by smart products to interact with the user in an intelligent way: in particular, context data (including sensor data), user profile, product capabilities, etc.
