UMLS::Interface::STFinder - provides the semantic type path information for the modules in the UMLS::Interface package.


This package provides the path information about semantic types in the UMLS Semantic Network for the modules in the UMLS::Interface package.

For more information please see the documentation.


 use UMLS::Interface::CuiFinder;
 use UMLS::Interface::STFinder;
 use UMLS::Interface::ErrorHandler;

 %params = ();

 $params{'realtime'} = 1;

 $cuifinder = UMLS::Interface::CuiFinder->new(\%params);
 die "Unable to create UMLS::Interface::CuiFinder object.\n" if(!$cuifinder);

 $stfinder = UMLS::Interface::STFinder->new(\%params, $cuifinder); 
 die "Unable to create UMLS::Interface::STFinder object.\n" if(!$stfinder);

 my $cell = "T025";
 my $bpoc = "T023";

 my $paths = $stfinder->_pathsToRoot($cell);
 print "The paths between cell ($cell) and the root:\n"; 
 foreach my $path (@{$paths}) { 
    print " => $path\n";

 print "\n\n";
 my $spaths = $stfinder->_findShortestPath($cell, $bpoc);
 print "The paths between cell ($cell) and bpoc ($bpoc): \n";
 foreach my $path (@{$spaths}) { 
    print " => $path\n";


To install the module, run the following magic commands:

  perl Makefile.PL
  make test
  make install

This will install the module in the standard location. You will, most probably, require root privileges to install in standard system directories. To install in a non-standard directory, specify a prefix during the 'perl Makefile.PL' stage as:

  perl Makefile.PL PREFIX=/home/sid

It is possible to modify other parameters during installation. The details of these can be found in the ExtUtils::MakeMaker documentation. However, it is highly recommended not messing around with other parameters, unless you know what you're doing.
