MorP is a system for automatic word class assignment on the basis of surface features. It has a very small lexicon of form words (%o entries), and for the rest works entirely on morphological and configurational patterns. This makes it robust and fast, and in spite of the (deliberate) restrictedness of the system, its performance reaches an average ac- curacy level above 91% when run on un- restricted Swedish text. Keywords: parsing, morphology. The development of the parser to be presented has been supported by the Swedish Research Council for the Humanities. The parser is called MorP, for morphology based parser, and the hypotheses behind it can be formulated thus: a) It is to a large extent possible to decide the word class of words in running text from pure surface criteria, such as th...
