{"pk":26428,"title":"Grounded Distributional Semantics for Abstract Words","subtitle":null,"abstract":"Since Harnad (1990) pointed out the symbol grounding prob-lem, cognitive science research has demonstrated that ground-ing in perceptual or sensorimotor experience is crucial to lan-guage. Recent embodied cognition theories have argued thatlanguage is more important for grounding abstract than con-crete words; abstract words are grounded via language. Dis-tributional semantics has recently addressed the embodied na-ture of language and proposed multimodal semantic models.However, these models are not cognitively plausible becausethey do not address the recent embodiment view of abstractconcepts. Therefore, we propose a novel multimodal distribu-tional semantics in which abstract words are represented indi-rectly through grounded representations of their semanticallyrelated concrete words. A simulation experiment demonstratedthat the proposed model achieved better performance in com-puting the word similarity than other multimodal or text-baseddistributional models. This finding suggests that the indirectembodiment view is plausible and contributes to the improve-ment of multimodal distributional semantics.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/2682c1fd","frozenauthors":[{"first_name":"Katsumi","middle_name":"","last_name":"Takano","name_suffix":"","institution":"The University of Electro-Communications1-5-1","department":""},{"first_name":"Akira","middle_name":"","last_name":"Utsumi","name_suffix":"","institution":"The University of Electro-Communications1-5-1","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T21:00:00+03:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26428/galley/16064/download/"}]}
