Classification
Ascent Xtrata Pro User's Guide 71
The above example shows that Politik has the highest confidence, and as such, would
normally become the classification result after the first step. But, Politik also has the
subtree classification option enabled with a threshold of 30% for the minimum
confidence and 5% for the minimum distance settings. Due to this lower value,
Energiepolitik, with 40% confidence, becomes the final classification result. The
confidence of 60% for Kultur doesn’t matter here, because only classes inside the
subtree below Politik are considered during this additional step.
Note Subtree classification will cascade down the entire branch of the tree so long as
the “Enable subtree classification” option is enabled for a parent at that level. Each
time this condition is met, another evaluation step using the child classes of the
current result is performed. In order for this nesting to work successfully, the
confidence and distance values at each level must be less than the preceding level,
otherwise, the different hierarchy levels will be in conflict.
X To configure subtree classification
