brownFreq.pl - Compute Information Content from the Brown Corpus
brownFreq.pl [--outfile=OUTFILE [--stopfile=STOPFILE] [--wnpath=WNPATH] [--resnik] [--smooth=SCHEME] FILES | --help --version]
This program reads the Brown Corpus and computes the frequency counts for each synset in WordNet. 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.
There are various forms of the Brown corpus available. The one we use for this program comes from the ICAME Collection of English Language Corpora, Second Edition, 1999. http://www.hit.uib.no/icame/cd
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
