Because poor quality semantic metadata can destroy the effectiveness of semantic web technology by hampering applications from producing accurate results, it is important to have frameworks that support their evaluation. However, there is no such framework developed to date. In this context, we proposed i) an evaluation reference model, which sketches some fundamental principles for evaluating semantic metadata, and ii) an evaluation framework, which provides a set of instruments to support the
detection of quality problems and the collection of quality metrics
for these problems. In this talk, I will present the reference model and evaluation framework.
