{"pk":30140,"title":"Controlling the retrieval of general vs specific semantic knowledge in the instancetheory of semantic memory","subtitle":null,"abstract":"Distributional models of semantic cognition commonly makesimplifying assumptions, such as representing word co-occurrence structure by prototype-like high-dimensional se-mantic vectors, and limit how retrieval processes may con-tribute to the construction and use of semantic knowl-edge. More recently, the instance theory of semantics (ITS,Jamieson, Avery, Johns, & Jones, 2018) reconceived a dis-tributional model in terms of instance-based memory, allow-ing context-specific construction of semantic knowledge at thetime of retrieval. By simulation, we show that additional en-coding and retrieval operations, consistent with learning andmemory theory, can play a crucial role in flexibly controllingthe construction of general versus specific semantic knowl-edge. We argue this consolidation of processing principlesholds insight for distributional theories of semantic cognition.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"distributional semantics; higher-order similarity;instance theory; surprise-driven learning; retrieval"}],"section":"Papers accepted as Posters, appearing in proceedings only","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6p09x9gp","frozenauthors":[{"first_name":"Matthew","middle_name":"J.C.","last_name":"Crump","name_suffix":"","institution":"Brooklyn College","department":""},{"first_name":"Randall","middle_name":"K.","last_name":"Jamieson","name_suffix":"","institution":"University of Manitoba","department":""},{"first_name":"Brendan","middle_name":"T.","last_name":"Johns","name_suffix":"","institution":"McGill University","department":""},{"first_name":"Michael","middle_name":"N.","last_name":"Jones","name_suffix":"","institution":"Indiana University – Bloomington","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30140/galley/19994/download/"}]}
