Query expansion - neighbours (Ex#2-

Query expansion - neighbours (Ex#2-8):
Ex#8 provided on average the best results, and
the best results for the Animals and the Wine
ontologies. However, for the Travel ontology
Ex#8 provided the fourth best results while
Ex#6 gave the best results for this ontology. It
was assumed that Ex#2 on average would
provide the best results but it turned out that it
provided the third best results. If we look at
both the standard deviation and mean results,
then Ex#2 yields the best results. This could
indicate that independent of the quality of the
ontology, Ex#2 would be the best choice.
