4.6 Scenarios that Invite Conversational Search

Our working group identified scenarios that invite conversational search. What emerged is (1) no other modality available (or best modality is different),(2) the task invites conversation. In this document, we motivate these key scenarios and propose research around prototypical tasks in this space. The associated key research challenges were identified in collecting, constructing and representing the rich multimodal contextual information of conversational search, summarizing and presenting the results in speech-only scenarios, design of conversational strategies and in evaluating the dialogue and search systems. Collaborative conversational search adds further challenges that consider the potentially highly interactive, multimodal and synchronous communication between humans and agents.
