Coordinations in noun phrases often pose the problem that elliptified parts have to be reconstructed for proper semantic inter- pretation. Unfortunately, the detection of coordinated heads and identification of el- liptified elements notoriously lead to am- biguous reconstruction alternatives. While linguistic intuition suggests that semantic criteria might play an important, if not su- perior, role in disambiguating resolution alternatives, our experiments on the re- annotated WSJ part of the Penn Treebank indicate that solely morpho-syntactic crite- ria are more predictive than solely lexico- semantic ones. We also found that the combination of both criteria does not yield any substantial improvement.
