Constructing a Valence Lexicon for a Treebank of German

Abstract

"Treebanks allow for the creation of a valence lexicon per side effect. The TüBa-D/Z valence lexicon has been created in lockstep with the development of the TüBa- D/Z treebank as such. For each verb encountered in the treebank, the annotators created a lexical entry that records the valence frames of the verbs contained in the sentence, unless they are already contained in the valence lexicon as result of previous annotation. The TüBa-D/Z valence lexicon currently contains a total of 8013 frames for 4896 distinct verb lemmas. Since treebank annotation is still ongoing, the lexicon will continue to grow. Such a lexicon has utility in its own right as a resource for lexicalized parsing and a variety of NLP applications. At the same time, the lexicon can serve as a source for aiding consistency of annotation and automatic detection of annotation errors"
