... have not been devel- oped. Our approach is based on redefining the task of lemmatisation as a category tagging task. Formu- lating lemmatisation as a tagging task allows the use of advanced tagging ... Geneva tanja.samardzic@unige.ch Abstract We present a novel approach to the task of word lemmatisation. We formalise lemmati- sation as a category tagging task, by describ- ing how...
