This document is a manual for coding aspects of the discourse
structure of dialogue. It was developed to serve as both as a starting
point for discussion and a tool for coding exercises prior to the 3rd
{\em Discourse Resource Initiative} (DRI) meeting, May 1998 in Chiba,
Japan. The manual focuses on coding common ground units (CGUs) to get to a
level of commonality between participants in dialogue, and then
intentional and informational units (IUs) that represent the higher-level,
hierarchical topic or purpose structure of dialogue.
