GClasses::GStemmer Class Reference

Detailed Description

This class just wraps the Porter Stemmer. It finds the stems of words. Examples: "cats"->"cat" "dogs"->"dog" "fries"->"fri" "fishes"->"fish" "pies"->"pi" "lovingly"->"lovingli" "candy"->"candi" "babies"->"babi" "bus"->"bu" "busses"->"buss" "women"->"women" "hasty"->"hasti" "hastily"->"hastili" "fly"->"fly" "kisses"->"kiss" "goes"->"goe" "brought"->"brought" As you can see the stems aren't always real words, but that's okay as long as it produces the same stem for words that have the same etymological roots. Even then it still isn't perfect (notice it got "bus" wrong), but it should still improve analysis somewhat in many cases.
