{"pk":32828,"title":"A Model-Based Approach to Case Adaptation","subtitle":null,"abstract":"In case-based reasoning, a given problem is solved by adapting the solutions to similar problems encountered in the past. A major task in case-based problem solving is to generate modifications that are useful for adapting a previous solution to solve the present problem. We describe a model-based method that uses qualitative models of cjises for generating useful modifications. The qualitative model of a case expresses a problem solver's comprehension of how the solution satisfies the constraints of the problem. We illustrate the model based method in the context of case-based design of physical devices. A designer's understanding of how the structure of a previously encountered design produces its functions is expressed in the form of a function structure model. The functional differences between a given problem and a specific case are mapped into structural modifications by a family of modification generation plans. Each plan is applicable to a specific type of functional difference, and uses the function structure model to identify the specific components that need to be modified. We discuss the evaluation of this model-based method in","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Paper Presentations -- Case Representation and Adoptation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/3hr72201","frozenauthors":[{"first_name":"Ashok","middle_name":"K.","last_name":"Goel","name_suffix":"","institution":"Georgia Institute of Technology","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1991-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/32828/galley/23888/download/"}]}
