Abstract |
Word-to-word dependency structures are useful for consistent representation and comparable evaluation of parsing results. However, most large-scale treebanks contain various variants of phrase structure trees, since automatic parsers usually produce constituent structures. We present a freely available extensible tool for converting phrase structure to dependencies automatically, and discuss its application to the NEGRA treebank of German. |
