Issues in the addition of ISO standard annotations to the Switchboard corpus

This paper analyzes the issues that arise when trying to add annotations to the dialogues in the Switchboard corpus according to ISO standard 24617-2, exploiting the existing SWBD-DAMSL annotations. These issues relate to differences between the two tag sets; to the highly multidimensional view that underlies the ISO standard; to differences in segmenting the dialogues into functional units; to the use of in-line markups for certain phenomena in Switchboard, and to the use of intra-dialogue dependence relations as defined in the ISO standard. The analysis is supplemented by a discussion of how the existing annotations may be helpful to semi-automatically create a fullyfledged ISO standard annotation alongside the existing SWBD-DAMSL annotation.
