Flat noun phrase structure was, up until re- cently, the standard in annotation for the Penn Treebanks. With the recent addition of inter- nal noun phrase annotation, dependency pars- ing and applications down the NLP pipeline are likely affected. Some machine translation systems, such as TectoMT, use deep syntax as a language transfer layer. It is proposed that changes to the noun phrase dependency parse will have a cascading effect down the NLP pipeline and in the end, improve ma- chine translation output, even with a reduc- tion in parser accuracy that the noun phrase structure might cause. This paper examines this noun phrase structure’s effect on depen- dency parsing, in English, with a maximum spanning tree parser and shows a 2.43%, 0.23 Bleu score, improvement for English to Czech...
