#25022In order to deal with ambiguity , the MORphological PArser MORPA is provided with a probabilistic context-free grammar (PCFG), i.e. it combines a conventional context-free morphological grammar to filter out ungrammatical segmentations with a probability-based scoring function which determines the likelihood of each successful parse.
