semCorRawFreq.pl - Compute Information Content from SemCor corpus (raw form, without using sense-tags)


  semCorRawFreq.pl --outfile FILE [--stopfile FILE] [--resnik]
   [--wnpath PATH] [--smooth SCHEME] {--stdin 
   | --infile FILE [--infile FILE ...]}
   | --help | --version


This program reads SemCor files and computes the frequency counts for each synset in WordNet, ignoring the sense tags in the corpus (treating it like a raw text corpus). These frequency counts are used by various measures of semantic relatedness to calculate the information content values of concepts. The output is generated in a format as required by the WordNet::Similarity modules for computing semantic relatedness.

The SemCor data we use comes from Rada Mihalcea, who has mapped SemCor from its original version to each successive version of WordNet. In this program we ignore the SenseTags and simply treat SemCor as raw text. This is to allow for the comparison of the effect of counting from sense tags (as done in semCorFreq.pl) versus raw or plain word forms (as done here).

A more detailed description of how information content is calculated can be found in rawtextFreq.pl. This program uses exactly the same techniques as described there.



    The name of a file to which output should be written


    A file containing a list of "stop" words that will not be
    considered during the frequency computation


    Use Resnik (1995) frequency counting


    Location of the WordNet data files (e.g.,


    Smoothing should used on the probabilities computed. SCHEME can
    only be ADD1 at this time


    Use this flag to provide input via the standard input


    Get the input from the specified file.
