{"pk":31360,"title":"A Case-Based Approach to Problem Formulation","subtitle":null,"abstract":"In domains requiring complex relational representations, simply expressing a new problem may be a complex, error-prone, and time-consuming task. This paper presents an approach to problem formulation, termed case-based formulation (CBF), that uses previous cases as a model and a guide for expressing new cases. By expressing new problems in terms of old, C B F can potentially increase the speed and accuracy of problem formulation, reduce the computational expense of retrieval, and determine the relevant similarities and differences between a new case and and the most similar old cases as a side-effect of expressing the new case. Three forms of C B F can be distinguished by the extent to which the retrieval and adaptation of previous cases are automated and the extent to which the facts of multiple cases Can be combined. A n initial implementation of one form of C B F is described and its ability to use previous cases to increase the efficiency and accuracy of new-case formalization is illustrated with a complex relational case.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5bx3j2vg","frozenauthors":[{"first_name":"L.","middle_name":"Karl","last_name":"Branting","name_suffix":"","institution":"University of Wyoming","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1992-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/31360/galley/22429/download/"}]}
