Structural prediction in incremental dependency parsing

Abstract

For dependency structures of incomplete sentences to be fully connected, nodes in addition to those corresponding to the words in the sentence prefix are necessary. We analyze a German dependency corpus to estimate the extent of such predictive structures. We also present an incremental parser based on the WCDG framework and describe how the results from the corpus study can be used to adapt an existing weighted constraint dependency grammar for complete sentences to the case of incremental parsing. © 2013 Springer-Verlag.
