Computes the Jaccard index between two trees.
Usage
jaccard_treeharp(th1, th2, weighted = FALSE)
Arguments
- th1
A TreeHarp object.
- th2
A TreeHarp object.
- weighted
A logical value, indicating if the weighted Jaccard
similarity should be computed.
Value
A real number between 0 and 1.
Details
The unweighted form is just the cardinality of the intersection
of the two sets of tokens, divided by the union of the two sets.
The weighted form is described on the WIkipedia page:
