Linguistic resources required by the factored lexicon. Equivalent resources for Arabic and French do not presently exist. The ATB lacks gold lemmas and a French morphological ranker equivalent to MADA—which can produce the full set of morphosyntactic features specified in the ATB—has not been developed. Morfette is effectively a discriminative classifier that treats analyses as atomic labels, whereas MADA utilizes a morphological generator.
