We analyze question-answer pairs in a variety of ways, for three different kinds of yes/no questions. We find that the classification of yes/no questions described in (Carletta et al., 1995) for the Edinburgh map task corpus correlates well with whether a response will be a bare yes or no, a yes or no plus additional speech, or just speech without an overt yes or no. Correlation with responses described as “direct” or “indirect” is less good. We also find that the strength of a question’s expectation for a YES response correlates with the move type, the form of the response, and lexical yes choices; and that the move type correlates with the form of the question and with turn-taking schema.
