Semantic distance metrics.
|
|
TonalSpaceEditDistance
Original tonal space distance metric computed as the edit distance
of the step vectors and functions of the path through the tonal
space implied by the semantics.
|
|
|
LargestCommonEmbeddedSubtrees
Tonal space distance metric computed as the size of the largest
subtree that can be embedded in the dependency graphs of two
logical forms.
|
|
|
OptimizedDependencyRecovery
Aligns the two dependency graphs in the way that optimizes their
dependency recovery and reports that dependency recovery.
|
|
|
DependencyRecovery
Exact dependency recovery metric.
|
|
|
RandomDistance
Returns a distance by picking a random number.
|
|
|
DependencyGraphSize
This is a baseline metric that does nothing clever.
