I am trying to do an invesigation into the use of stemmer on text classification, however can anyone direct me to material on the kuhlen stemmer. The node description suggests it uses the kuhlen algorithum however my searches on google scholar are not bring back much about how the kuhlen stemmer/ algoritum works.
The Kuhlen stemmer algoorithm is a stemming algorithm, not a lemmatizer. See http://tech.knime.org/forum/knime-textprocessing/kuhlen-stemmer-what-is-the-algorithm for the reference.
