Abstract

The paper presents a system, LemmaGen, for learning Ripple Down Rules specialized for automatic generation of lemmatizers. The system was applied to 14 different lexicons and produced efficient lemmatizers for the corresponding languages. Its evaluation on the 14 lexicons shows that LemmaGen considerably outperforms the lemmatizers generated by the original RDR learning algorithm, both in terms of accuracy and efficiency
