Confirm (DIT): S believes that A correctly has the weak belief that the semantic content of the check is true.Confirm (Verbmobil): With an utterance expressing a CONFIRM the speaker wraps up the result of the negotiation (or a part thereof). This is done by repeating parts of the completed task, i.e. for appointment scheduling a recapitulation (complete or partial) of the agreed date/place. Note: This dialogue act often also signals the closure of the task. If no information from the task domain is given in the utterance, though, it is likely to be a CLOSE. CONFIRM can also be abused as an ACCEPT if the set of confirmed items include a piece that has not been accepted yet.
