{"pk":30557,"title":"\"Word Pronunciation as a Problem in case-Based Reasoning\"","subtitle":null,"abstract":"English word pronunciation is a challenging knowledge acquisition problem in which general rules are subject to frequent exceptions of an arbitrary nature. W e have developed a supervised learning system, PRO, which learns about English pronunciation by training with words and their dictionary pronunciations. PRO organizes its knowledge in a case-based memory which preserves fragments of training items but does not remember specific training items in their entirety. After P R O has created a Caise Base in response to a training set, it can pronounce novel test words with substantial degrees of success. Test items are processed by generating a search space in the form of a lateral inhibition network and embedding this search speu:ein a larger network that reflects PRO's previous training experience with relevant fragments.Spreading activation and network relaxation are then used to arrive at a preferred pronunciation for the given test item. In this paper we report preliminary test results based on a trainingcorpus of 750 words and a test set of 300 words.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"learning"},{"word":"case-based reasoning"},{"word":"parallel processing\nsession preference: full paper"}],"section":"Linguistics I","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5466r925","frozenauthors":[{"first_name":"Wendy","middle_name":"G.","last_name":"Lehnert","name_suffix":"","institution":"Universiity of Massachusetts","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1987-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30557/galley/20406/download/"}]}
