Abstract:	In this paper, we use a feature model of the semantics of
		plural determiners to present an approach to grammar checking
	        for definiteness.
		Using neural network techniques, a semantics -- morphological 
		category mapping was learned.
		We then applied a textual encoding technique to the 125 
		occurences of the relevant category in a 10000 word narrative 
		text and learned a surface -- semantics mapping.
		By applying the learned generation function to the newly 
		generated representations, we achieved a correct category 
		assignment in many cases (87\%). 
		These results are considerably better than a direct surface 
		categorization approach (54 \%), with a baseline (always
		guessing the dominant category) of 60 \%.
		It is discussed, how these results could be used in 
		multilingual NLP applications.
