Fig. 13.5.
Degree changes of the tenth nodes with different thresholds
points denotes the ratios of the degrees of the largest ten nodes to the sum of
degrees of all nodes. And the label of this figure describes the identifications of
posters in the BBS forum. The other points in one curve denote the ratio of the
ten degrees to the sum of degrees with different thresholds.
When the basis threshold is 0.0005, the changes of the ratios of these node
degrees are quite acute. For example, the degree ratio of the node that poster
identification is 65896 only is the last one of ten ratios with threshold 0.0005,
while the threshold increases, the ratio is always in the top three of these ratios.
In addition, there is a significant difference between the ratios of ten nodes
when the threshold increases, which is not same as the changes of other five
