Linguists use treebanks as resource for collecting evidence of phenomena which cannot be easily recovered from data that is annotated at word level only, this includes collecting quantitative data, getting non-categorical information such as heaviness or finding natural sounding counter examples 1 (e.g. Uszkoreit et al. (1998); Arnold et al. (2000); Bresnan et al. (to appear)) 2. Tools such as TIGERSearch allow us easy access to the encoded information. 3 This poster presents work on the Tübinger Baumbank deutscher Zeitungssprache (Tüba-D/Z). It describes the encoding of coordination phenomena in the treebank and gives a qualitative and quantitative survey. 2 The TüBa-D/Z Treebank It is a corpus of newspaper texts which currently comprises about 22 000 sentences (more than 381 000 tokens) taken from the Wissenschafts-CD of ’die tageszeitung ’ (taz). The annotation combines information on inflectional morphology, part of speech, phrase structure (or rather recursive chunking), grammatical dependencies and topological fields. In addition, it includes marking of named entities and annotation of anaphoric and coreference relations (cf. Hinrichs et al. (2004)).
