{"pk":30771,"title":"Selecting The Best Case For A Case-Based Reasoner","subtitle":null,"abstract":"The most important support process a case-based reasoner needs is a memory for cases. Among its functions, the memory for cases must be able to select out the most appropriate cases for the case-based reasoner to use at any time. In this paper, we present the selection processes implemented in PARADYME , a case memory designed to work alongside a case-based reasoner.PARADYME has a two-step retrieval process. In the first step, it retrieves the set of partial matches from the memory. In the second, it selects out a small set of \"best\" matches. PARADYME chooses\"best\" cases using a set of six preference heuristics: goal-directed preference, salience,specificity, frequency, recency, and ease of adaptation. PARADYME is novel in two ways. Its use of preferences for choosing a best case means that its principles act as selectors rather than restrictors. And its emphasis in choosing best cases is on usefulness rather than similarity.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Paper Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9gv7f4zt","frozenauthors":[{"first_name":"Janet","middle_name":"L.","last_name":"Kolodner","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/30771/galley/20620/download/"}]}
