treebankFreq.pl - Compute Information Content from Penn Treebank 2
treebankFreq.pl [--outfile=OUTFILE [--stopfile=STOPFILE] [--wnpath=WNPATH] [--resnik] [--smooth=SCHEME] PATH | --help --version]
This program reads the Penn Treebank, Release 2, from the Linguistic Data Consortium, http://ldc.upenn.edu, and computes the frequency counts for each synset in WordNet. These frequency counts are used by the Lin, Resnik, and Jiang & Conrath 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.
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 listed words that will not be considered in the frequency counts. A sample file can be down- loaded from http://www.d.umn.edu/~tpederse/Group01/WordNet/words.txt
Location of the WordNet data files (e.g., /usr/local/WordNet-3.0/dict)
Use Resnik (1995) frequency counting
Smoothing should used on the probabilities computed. SCHEME can only be ADD1 at this time
