Not surprisingly, the categorical parser does not perform as well as the supervised statistical parser: only 92.7% of German words and 94.9% of English words (85.7% and 86.8%, respectively, of multisyllabic words) are syllabified correctly.
a more important result of parsing the corpus using the categorical parser is that its output can be used to define a model class (i.e., a set of PCFG rules) from which a model can be learned using EM.
