1. Product

The TüBa-J/S treebank is a syntactically annotated corpus of spontaneous speech dialogs. The dialogs were recorded and transcribed in the project VerbMobil. The treebank currently comprises approximately 18.000 sentences. It is annotated on three levels: the lexical level, the phrasal level, and the clausal level. In addition to constituent structure, annotated trees contain edge labels between nodes. These edge labels encode grammatical functions (as relations between phrases) and the distinction between heads and non-heads (as phrase-internal relations).

The TüBa-J/S treebank is available in two different formats: the original constituent-based format and the dependency-based version that was used in the CoNLL-X Shared Task.

Copyright of the linguistic annotation of TüBa-J/S is to the Seminar für Sprachwissenschaft at the Eberhard-Karls Universität Tübingen.
