Gruenstein Alexander, Niekrasz John, Purver Matthew. Meeting structure annotation: Data and tools, in Proceedings of the 6th SIGdial Workshop on Discourse and Dialogue, pp. 117-127, Sep 2005.
We present a set of annotations of hierarchical topic segmentations and action item sub-dialogues collected over 65 meetings from the ICSI and ISL meeting corpora, designed to support automatic meeting understanding and analysis. We describe an architecture for representing, annotating, and analyzing multi-party discourse, including: an ontology of multimodal discourse, a programming interface for that ontology, and an audiovisual toolkit which facilitates browsing and annotating discourse, as well as visualizing and adjusting features for machine learning tasks.
