Snowball English
This package implements the English language
Snowball stemmer.
Implementation
The English language stemmer comprises preprocessing, a number of steps,
and postprocessing. Each of these is defined in a separate file in this
package. All of the steps operate on a SnowballWord
from the
snowballword
package and modify the word in place.
Caveats
There is a single difference between this implementation and the original.
Here, all apostrophes on the left hand side of a word are stripped off before
the word is stemmed.
