[R-1.4.0] minimum spanning tree of large ontology
...ogy is not only DAG, the problem is non trivial and
therefore decided to use R with the powerful e1071
library (allShortestPaths) to do that. That method requires to provide a
distance matrix between the
various objects. My ontology contains 32768 objects and therefore I have
to load a matrix of 32768x32768.
Values in the matrix are set to 1 for those pair of terms that have a link
(semantic or hyper/hypo-nimic).
I am trying to reproduce at least part of the infrastructure described in
the following work
