Name

Text::SenseClusters::LabelEvaluation::SimilarityScore - Module for getting the similarity score between the contents of the two files.

SYNOPSIS

	# The following code snippet will show how to use SimilarityScore.
	package Text::SenseClusters::LabelEvaluation::Test_SimilarityScore;

	# Including the LabelEvaluation Module.
	use Text::SenseClusters::LabelEvaluation::SimilarityScore;


	my $firstString = "IBM::: vice president, million dollars, Wall Street, Deep Blue, ".
				"International Business, Business Machines, International Machines, ".
				"United States, Justice Department, personal computers";
	my $secondString = "vice president, million dollars, Deep Blue, International Business, ".
					"Business Machines, International Machines, United States, Justice Department";
					 
	my $similarityObject = Text::SenseClusters::LabelEvaluation::SimilarityScore->
			new($firstString,$secondString, "../stoplist.txt");
	
	#my $score = $similarityObject->computeOverlappingScores();
		my ($score, %allScores) = $similarityObject->computeOverlappingScores();

	print "Score:: $score \n";
	print "Lesk Score :: $allScores{'lesk'} \n";
	print "Raw Lesk Score :: $allScores{'raw_lesk'} \n";
	print "precision Score :: $allScores{'precision'} \n";
	print "recall Score :: $allScores{'recall'} \n";
	print "F Score :: $allScores{'F'} \n";
	print "dice Score :: $allScores{'dice'} \n";
	print "E Score :: $allScores{'E'} \n";
	print "cosine Score :: $allScores{'cosine'} \n";
	print "\n\n";

DESCRIPTION

This module provide a function that will compare the two strings and return the overlapping scores. Please refer the following for details description how it will calculate the similarity score: http://search.cpan.org/~tpederse/Text-Similarity-0.09/

Constructor: new()

This is the constructor which will create object for this class. Reference : http://perldoc.perl.org/perlobj.html

This constructor takes these argument and intialize it for the class:

1. $clusterData :  Datatype: String
	  This variable contains the labels generated by the SenseClusters.
2. $scoreObject :  Datatype: String
	  This variable contains the Gold standard key's data.
3. $stopListFileLoc :  Datatype: String
	  This variable contains the user defined location for the stop list file.
				

Function: computeOverlappingScores

Function that will compare the labels file with the wiki files and will return the overlapping score.

@argument1 : Name of the cluster file. @argument2 : Name of the file containing the data from Wikipedia. @argument3 : Name of the file containing the stop word lists.

@return : Return the overlapping scores between these files.

@description : 1). Reading the file name from the command line argument. 2). Invoking the Text::Similarity::Overlaps module and passing the file names for similarity comparison. 3). Then overlapping scores obtained from this module is returned as the similarity value.
