Multi-tasking and collaborative activities in dialogue systems
Oliver Lemon, Alexander Gruenstein, Alexis Battle, Stanley Peters · 2002
We explain dialogue management techniques for collaborative activities with humans, 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 the system.
