We have conducted a set of experiments to
validate the FVC algorithm proposed in Section 2.
The goal of the experiments is to measure the
sensitivity w.r.t. both the components of the FVC
algorithm and the ontologies of different
granularity. Further, we propose using Normalised
Google Distance (NGD) (described in Section 3.3)
and two additional measures to get a representative
value of the FV quality. In this section, we present
the ontologies used and the tests conducted, and
analytically evaluate the approach. In the next two
sections, we present and discuss the results of the
experiments.
