{"pk":30891,"title":"An Internal Contradiction of Case-Based Reasoning","subtitle":null,"abstract":"In a case-based reasoning system, one simple approach to assessment of similarity of cases to a given problem situation is to create a linear ordering of the cases by similarity according to each relevant domain factor. Using Arrow's Impossibility Theorem, a result from social welfare economics, a paradox is uncovered in the attempt to find a consistent overall ordering of cases by similarity that satisfactorily reflects these individual rankings. The implications of the paradox for case-based reasoning are considered.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Paper Presentations -- Group 1: Reasoning","is_remote":true,"remote_url":"https://escholarship.org/uc/item/2hz0m2s8","frozenauthors":[{"first_name":"David","middle_name":"B.","last_name":"Skalak","name_suffix":"","institution":"University of Massachusetts","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/30891/galley/20740/download/"}]}
