TM::Analysis - Topic Maps, analysis functions SYNOPSIS
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; DESCRIPTION
This package contains some topic map analysis functionality. INTERFACE
statistics 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. orphanage 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'); entropy 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. SEE ALSO
