چکیده
Ontology-based data access has received a lot of attention recently, yet there is no clear methodology to evaluate a “semantically enriched” information system in general or an ontology based data access system in particular. The quality of such an information system clearly depends on how well your data fits your class-level ontology, and how well these two components fit your queries. This paper presents a generic, flexible framework for this kind of analysis: it can be used, e.g., to compare two class-level ontologies w.r.t. their fitness for a given kind of data and query set. We apply the framework to an example case and show how it helps to answer relevant modelling and representation questions.
