NAME ^

UMLS::SenseRelate::TargetWord - A Perl module that implement the target word word sense disambiguation using the sense relate wsd algorithm based on the semantic similarity and relatedness options from the UMLS::Similarity package.

DESCRIPTION ^

This package provides an implementation of the senserelate word sense disambiguation algorithm using the semantic similarity and relatedness options from the UMLS::Similarity package.

SYNOPSIS ^

 use UMLS::Similarity;
 use UMLS::SenseRelate::TargetWord;

 #  initialize option hash and umls
 my %option_hash = ();
 my $umls        = "";
 my $meas        = "";
 my $senserelate = "";
 my $params      = "";

 #  set interface     
 $option_hash{"t"} = 1;
 $option_hash{"realtime"} = 1;
 $umls = UMLS::Interface->new(\%option_hash);

 #  set measure
 use UMLS::Similarity::path;
 $meas = UMLS::Similarity::path->new($umls);

 #  set senserelate
 $params{"measure"} = "path";
 $senserelate = UMLS::SenseRelate::TargetWord->new($umls, $meas, \%params);

 #  set the target word
 my $tw = "adjustment";        

 #  provide an instance where the target word is in <head> tags
 my $instance = "Fifty-three percent of the subjects reported below average ";
    $instance .= "marital <head>adjustment</head>.";

 my ($hashref) = $senserelate->assignSense($tw, $instance, undef);

 if(defined $hashref) {
    print "Target word ($tw) was assigned the following sense(s):\n";
    foreach my $sense (sort keys %{$hashref}) {
      print "  $sense\n";
    }
 }
 else {
    print "Target word ($tw) has no senses.\n";
 }

INSTALL ^

To install the module, run the following magic commands:

  perl Makefile.PL
  make
  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/bridget

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.

DESCRIPTION ^

PARAMETERS ^

UMLS::SenseRelate parameters

  'window'       -> This parameter determines the window size of the 
                    context on each side of the target word to be used 
                    for disambiguation
  'weight'       -> This parameter weights the similarity scores based
                    on how far the term or word is from the target word
  'restrict'     -> This parameter restricts the context to be only 
                    terms/words that map to concepts in the UMLS

  'stoplist'     -> This parameter disregards stopwords when creating 
                    the window created on the fly (in realtime). 

  'compound'     -> This parameter indicates that compounds exist in 
                    the input instance denoted by an underscore

  'trace'        -> This parameters indicates that the trace information
                    should be printed out to the file
