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:
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:
Holds a list reference to all topic ids which have no type.
Holds a list reference to all topic ids which have no instance.
Holds a list reference to all topic ids which have no superclass.
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.
