I guess there are a few points
- it is impossible to stem with total accuracy using rules alone
- combining a rule based stemmer with a dictionary could also be error
prone. Unrelated words can have the same stem - consider the past tense of
see and the stem of sawing ( cutting wood )
I guess you could solve some of these by stemming (actually, lemmatising
is probably more accurate, since you'll almost certainly need part of
speech information to do it with any accuracy) to the wordnet number,
for which the meaning is unique.
But there are still ambiguous sentences where you don't know which word
it is. To use the example just given, "I saw wood" is pretty ambiguous,
without having more context.
