It must react appropriately to changes in the situation, where what is appropriate depends to a large extent on the overall problem-solving context. In order to do this, the reasoner needs to have explicit knowledge about the context it is in. In our approach, the problem-solving context is represented explicitly as a contextual schema. When presented with a problem, the reasoner finds an appropriate contextual schema, then uses it to influence its problem-solving behavior. The reasoner uses the contextual schema to recognize important changes in the problem-solving situation and to respond appropriately to those changes Our approach is implemented in the medic program (Turner, 1988b; Turner, in preparation), medic is medical diagnostic consultant whose domain is puLmonology.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Poster Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9859737s","frozenauthors":[{"first_name":"Roy","middle_name":"M.","last_name":"Turner","name_suffix":"","institution":"Georgia Institute of Technology","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1989-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30870/galley/20719/download/"}]}
