TM::Analysis - Topic Maps, analysis functions
use TM::Materialized::AsTMa; my $tm = new TM::Materialized::AsTMa (file => 'test.atm'); $tm->sync_in; Class::Trait->apply ($tm, 'TM::Analysis'); print Dumper $tm->statistics; print Dumper $tm->orphanage;
This package contains some topic map analysis functionality.
This (currently quite limited) function computes a reference to hash containing the following fields:
nr_toplets
Nr of midlets in the map. This includes ALL midlets for topics and also those for assertions.
nr_asserts
Nr of assertions in the map.
nr_clusters
Nr of clusters according to the cluster function elsewhere in this document.
cluster
This computes all topics which have either no supertype and also those which have no type. Without further parameters, it returns a hash reference with the following fields:
untyped
Holds a list reference to all topic ids which have no type.
empty
Holds a list reference to all topic ids which have no instance.
unclassified
Holds a list reference to all topic ids which have no superclass.
unspecified
Holds a list reference to all topic ids which have no subclass.
Optionally, a list of the identifiers above can be passed in so that only that particular information is actually returned (some speedup):
my $o = TM::Analysis::orphanage ($tm, 'untyped');
This method returns a hash (reference) where the keys are the assertion types and the values are the individual entropies of these assertion types. More frequently used (inflationary) types will have a lower value, very seldomly used ones too. Only those in the middle count most.
