Needing and Wanting in Academic Lectures: Profiling the academic lecture across context [pdf]Paper  abstract   bibtex   
In this paper we outline the distribution of processes of needing and wanting in academic lectures across different disciplines, different phases in courses and individual lectures and different levels of education. In so doing, we consider who or what is needing and wanting and who or what is needed and wanted. This study forms part of a wider research program that uses multi-modal markers of importance to automatically extract key information from lectures as a step towards being able to identify and track contextually relevant importance in spoken language in real time for automatic summarization. We base our contextual analysis on the contextual models of Butt and Moore, which we further adapt for our purposes following Wegener (2011, 2015) and Cassens and Wegener (forthcoming) though they are not the focus of this paper.
