Managing Information Quality in e-Science with Semantic Web Technology∗

We outline a framework for managing information quality (IQ) in e-Science, using ontologies, semantic annotation of resources, and rules. Scientists define the quality characteristics that are of importance in their particular domain by extending an OWL DL IQ ontology, which classifies and organises these domain-specific quality characteristics within an overall quality management framework. RDF is used to annotate resources with IQ indicators. Rules are used to specify scientists’ IQ preferences. As an illustration of our approach, we present an example Web service that computes IQ annotations for experiment datasets in biology.
