Towards Personal Assistants that Can Help Users Plan

In this paper, we present an intelligent personal assistant, called Uhura, that handles requests involving multiple, interrelated goals and activities by efficiently producing a coherent plan. Uhura achieves this by integrating a collaborative dialog manager, a conflict-directed planner with spatial and temporal reasoning capabilities, and a large-scale knowledge graph. We also present a user survey that assesses the usefulness of the plans produced by Uhura in urban travel planning.
