NAME "Lingua::EN::Infinitive" - Determine the infinitive form of a conjugated word SYNOPSIS use Lingua::EN::Infinitive; my($spell) = Lingua::EN::Infinitive -> new(); my($word) = 'rove'; # Method 1: my($word1, $word2, $suffix, $rule) = $spell -> stem($word); # Method 2: $spell -> stem($word); my($word1, $word2, $suffix, $rule) = ( $spell -> {'word1'}, # A possibility. $spell -> {'word2'}, # A possibility, or ''. $spell -> {'suffix'}, $spell -> {'rule'}, ); print "Conjugated: $word. Infinitive: $word1. \n"; DESCRIPTION Determine the infinitive form of a conjugated word. Also, determine the suffix used to identify which rule to apply to transform the conjugated word into the infinitive form. Either 1 or 2 possible infinitives are returned. You must check that the first is really an English word. If it is, then it is the result. If it is not valid, then check the second. Failure to deconjugate is indicated by $word1 eq ''. In general, you can ignore the 3rd and 4th values returned from stem(). The algorithm is based on McIlroy's article (see below), after first checking for irregular words. In the hash 'suffix2Rule', you'll see the key 'order'. This specifies the sort order in which to check McIlroy's rules. I've changed his ordering in a number of places. INSTALLATION You install "Lingua::EN::Infinitive", as you would install any perl module library, by running these commands: perl Makefile.PL make make test make install If you want to install a private copy of "Lingua::EN::Infinitive" in your home directory, then you should try to produce the initial Makefile with something like this command: perl Makefile.PL LIB=~/perl or perl Makefile.PL LIB=C:/Perl/Site/Lib If, like me, you don't have permission to write man pages into unix system directories, use: make pure_install instead of make install. This option is secreted in the middle of p 414 of the second edition of the dromedary book. WARNING Don't make the false assumption that "$word1$suffix" eq $word or "$word2$suffix" eq $word REFERENCE Title: Development of a Spelling List Author: M.
