We focus on dialogue management for collaborative activities, involving multiple concurrent tasks. Conversational context for multiple concurrent activities is represented using a ``Dialogue Move Tree'' and an ``Activity Tree'' which support multiple interleaved threads of dialogue about different activities and their execution status. We also describe the incremental message selection, aggregation, and generation method employed in this context. The generation component must also be able to handle contexts where there are multiple topics being co-ordinated by the conversation. We show how to use dynamic context representations for flexible interpretation and natural generation of dialogue contributions in such applications. We demonstrate that these techniques are viable in a dialogue system for multi-modal conversations with semi-autonomous mobile robots.
