DESCRIPTION

Word2vec::Spearmans is a Spearman's Rank Correlation Score Module for the Word2vec::Inteface package.

Main Functions

new

Description:

 Returns a new 'Word2vec::Spearmans' module object.

 Note: Specifying no parameters implies default options.

 Default Parameters:
    debugLog                    = 0
    writeLog                    = 0
    precision                   = 4
    isFileOfWords               = undef
    N                           = undef
    aCount                      = -1
    bCount                      = -1
    NValue                      = -1

Input:

 $debugLog                    -> Instructs module to print debug statements to the console. (1 = True / 0 = False)
 $writeLog                    -> Instructs module to print debug statements to a log file. (1 = True / 0 = False)
 $isFileOfWords               -> Specifies the word option, default is Auto-Detect. (undef = Auto-Detect, 0 = CUI Terms, 1 = Word Terms)
 $N                           -> Specifies the N option, default is undef. (defined = Print N / undef = Do Not Print N)
 $aCount                      -> Term count for $aFile post Spearman's Rank Correlation calculation.
 $bCount                      -> Term count for $bFile post Spearman's Rank Correlation calculation.
 $NValue                      -> N Value post Spearmans's Rank Correlation calculation.

 Warning: Only debugLog, writeLog, precision, word and N variables should be specified.

Output:
