Parallel Syntactic Annotation in CReST


In this paper, we introduce the syntactic annotation of the CReST corpus, a corpus of natural language dialogues obtained from humans performing a cooperative, remote search task. The corpus contains the speech signals as well as transcriptions of the dialogues, which are additionally annotated for dialogue structure, disfluencies, and for syntax. The syntactic annotation comprises POS annotation, Penn Treebank style constituent annotations, dependency annotations, and combinatory categorial grammar annotations. The corpus is the first of its kind, providing parallel syntactic annotation based on three different gram- mar formalisms for a dialogue corpus. All three annotations are manually corrected, thus providing a high quality resource for linguistic comparisons, but also for parser evaluation across frameworks.
