In this paper, we investigate distinctive utterances in non-task-oriented conversational dialogue through the comparison between task-oriented dialogue and non-task-oriented conversational dialogue. We then found that Indirect Responses (IRs) and Clarification Requests (CRs) are significant in non-taskoriented conversational dialogue. IRs are cooperative responses to other's question, while CRs are clarification questions. We analyzed the rhetorical relations about IRs and CRs. We then found that the IRs are generated by evidence and causal relations, while the CRs are generated by elaboration relation and causal relations.
