But they typically ignore the potential interaction amongst those word tokens. Unlike currently popular methods, we propose a deep model which uses feature attribution and identification of dependencies to support the learning of interpretable representations that will support creation of hierarchical explanations. In addition, hierarchical explanations provide a basis for visualizing how words and phrases are combined at different levels of abstraction, which enables end-users to better understand the prediction process of a deep network. Our study uses multiple well-known datasets to demonstrate the effectiveness of our approach, and provides both automatic and human evaluation.<\/jats:p>","DOI":"10.3233\/faia230266","type":"book-chapter","created":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T09:00:08Z","timestamp":1695978008000},"source":"Crossref","is-referenced-by-count":0,"title":["From Intermediate Representations to Explanations: Exploring Hierarchical Structures in NLP"],"prefix":"10.3233","author":[{"given":"Housam K.B.","family":"Babiker","sequence":"first","affiliation":[{"name":"Department of Computing Science, University of Alberta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mi-Young","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Science, Augustana Faculty, University of Alberta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randy","family":"Goebel","sequence":"additional","affiliation":[{"name":"Department of Computing Science, University of Alberta"},{"name":"Alberta Machine Intelligence Institute, University of Alberta"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2023"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA230266","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T09:00:09Z","timestamp":1695978009000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA230266"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,9,28]]},"ISBN":["9781643684369","9781643684376"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia230266","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,9,28]]}}}
