Annotation of Information Structure: an Evaluation across different Types of Texts

Abstract

We report on the evaluation of information structural annotation according to the Linguistic Information Structure Annotation Guidelines (LISA, (Dipper et al., 2007)). The annotation scheme differentiates between the categories of information status, topic, and focus. It aims at being language-independent and has been applied to highly heterogeneous data: written and spoken evidence from typologically diverse languages. For the evaluation presented here, we focused on German texts of different types, both written texts and transcriptions of spoken language, and analyzed the annotation quantitatively and qualitatively. 1.
