Considering data obtained from a corpus of database QA dialogues, we address the nature of the discourse structure needed to resolve the several kinds of contextual phenomena found in our corpus. We look at the thematic relations holding between questions and the preceding context and discuss to which extent thematic relatedness plays a role in discourse structure.
