The research methods used in this phase were engineering and experimentation, but also
influenced by the results from the previous phases. Engineering was used to construct
an alternative FVC approach to the one created in Phase II. The new approach was
based on lessons learned. A set of experiments was conducted and the results analysed
with respect to both FV quality and ontology quality. The quality was measured using intrinsic and extrinsic measures with respect to ontologies of different granularity. The
proposed measures were validated in an experiment with real users. The same
ontologies as in Phase II were used.
