The objective of this phase was to get a better understanding of the sensitivity of the
FVC components with respect to ontology quality. Therefore, a new prototype was
implemented and a set of experiments was conducted in a controlled environment
(Wohlin et al., 2003) based on the lessons learned from the user experiment conducted
in Phase II. Furthermore, to evaluate the quality of the FVs, a set of FV quality
measures was proposed and validated.
