... discourse models. To allow plans about plans, i.e., metaplans, we need a vocabulary for referring to and describing plans. Developing a fully adequate formal model would be a large research effort ... conventional indirect speech acts can be accounted for using a metaplan for each form. 2.2 Plan Recognition The plan recognizer attempts to recognize the plan( s) that l...
