{"pk":30939,"title":"Towards a Failure-driven Mechanism for Discourse Planning: a Characterization for Learning Impairments","subtitle":null,"abstract":"In the process of generating discourse, speakers generate utterances which directly achieve the communicative goal of conveying an information item to a hearer, and they also generate utterances which prevent the disruption of correct beliefs maintained by a hearer or the inception of incorrect beliefs. In this paper, we propose a representation scheme which supports a discourse planning mechanism that exhibits both behaviors. Our representation is based on a characterization of commonly occurring impairments to the knowledge acquisition process in terms of a model of a hearer's beliefs. As a testbed of these ideas, a discourse planner called WISHFUL is being implemented in the domain of high-school algebra.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Paper Presentations -- Group 2: Language","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5f50m6gb","frozenauthors":[{"first_name":"Ingrid","middle_name":"","last_name":"Zukerman","name_suffix":"","institution":"Monash University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1990-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30939/galley/20788/download/"}]}
