Efficient Lemmatizer that avoids dictionary lookup

Question

I want to convert string like 'eat' to 'eating', 'eats'. I searched and found the lemmatization as the solution, but all the lemmatizer tools that I have come across uses wordlist or dictionary-lookup. Is there any lemmatizer which avoids dictionary lookup and gives high efficiency, may be a lemmatizer that is based on rules. Yes and I am not looking for "stemmer".

Answer 1

You can try LRBL: a rule-based lemmatizer

It uses the concept of recursive acronyms.
