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
There are various forms of the Brown corpus available. The one we
use for this program comes from the ICAME Collection of English

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-
