NAME

ROADS::Porter - A class to perform stemming using the Porter algorithm.

SYNOPSIS

  use ROADS::Porter;
  print join(" ", stem("wubbleyou")),  "\n";

DESCRIPTION

This class defines an implementation of the Porter stemming algorithm.

METHODS

@stemmed_terms = stem( term );

The stem method operates on a single term term at a time, and so must be wrappered by any code which is aiming to stem multiple search terms. It returns a scalar array of terms found through the stemming algorithm, including itself.

BUGS

It's not clear that the Porter algorithm is a very useful for this sort of thing! Some of the results look very silly.
