probabilistic partofspeech tagging using decision trees
Helmut Schmid
Due to the special structure of presentations , this corpus will be particularly demanding with respect to the required preprocessing components of an information retrieval system . The three preprocessing steps ( tokenization , POS-tagging , lemmatization ) are performed using TreeTagger ( Schmid , 1995 ) . The resulting list of POS-tagged lemmas is weighted using the SMART ` ltc ' 8 tf.idf-weighting scheme ( Salton , 1989 ) .
