Such dialogues are challenging for a number of reasons when supported by dialogue systems. We introduce a model of Situated Dialogue Action (SAM) that represents system-supported dialogues between multiple participants with mixed intention sets triggered by non-collaborative dialogue situations. Selected parts of SAM are instantiated by means of a Question-Answering (QA) system. We discuss our findings due to the instantiation in a QA setting and gave implications for future work.enText/Conference Paper1617-5468
