This directory includes misc Perl files that are needed to extract
unigram features, collocation features, and create stop lists. 
The functionality of 

count1.pl 
count1-esp.pl 
coll1.pl 

have been incorporated into version 0.5 of the Bigram Statistics
Package. However, the Duluth Senseval-2 systems are based on 
version 0.4 of the Bigram Statistics Package. In order to preserve
the original systems we have decided to continue to use these older
scripts. Note however that you can use Bigram Statistics Package
version 0.5 with these older scripts. In other words, if you have
Bigram Statistics Package version 0.5, you are not forced to use
the new options that support the above, you can still use the original
programs. 

The following programs are included in this directory but not
actually used in the Duluth system scripts. 

clean.pl
tilde.pl
tilde-rem.pl

The stop listing programs are not used in the scripts, but 
were used to create stop.list

stop.pl
stop-spa.pl
