After showing that PageRank, naively re-interpreted as an argumentation semantics for support frameworks, fails to satisfy some generally desirable properties, we propose a novel approach able to reconstruct PageRank as a gradual semantics of a suitably defined bipolar argumentation framework, while satisfying these properties. We then show how the theoretical advantages afforded by this approach also enjoy an enhanced explanatory power: we propose several types of argument-based explanations for PageRank, each of which focuses on different aspects of the algorithm and uncovers information useful for the comprehension of its results.<\/jats:p>","DOI":"10.3233\/ia-210095","type":"journal-article","created":{"date-parts":[[2021,7,30]],"date-time":"2021-07-30T10:54:36Z","timestamp":1627642476000},"page":"17-34","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Interpreting and explaining pagerank through argumentation semantics"],"prefix":"10.1177","volume":"15","author":[{"given":"Emanuele","family":"Albini","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, Universit\u00e0 degli Studi di Brescia, 25123 Brescia, Italy"},{"name":"Department of Computing, Imperial College London, South Kensington Campus SW7 2AZ London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pietro","family":"Baroni","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, Universit\u00e0 degli Studi di Brescia, 25123 Brescia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Rago","sequence":"additional","affiliation":[{"name":"Department of Computing, Imperial College London, South Kensington Campus SW7 2AZ London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Toni","sequence":"additional","affiliation":[{"name":"Department of Computing, Imperial College London, South Kensington Campus SW7 2AZ London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,7,28]]},"reference":[{"issue":"1999","key":"ref001","first-page":"1","volume":"54","author":"Page L.","year":"1998","journal-title":"World Wide Web Internet And Web Information Systems"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.1016\/j.ipm.2007.06.006"},{"key":"ref003","first-page":"2766","author":"Gori M.","year":"2007","journal-title":"Proceedings of the 20th International Joint Conference on Artificial Intelligence (IJCAI);"},{"key":"ref004","doi-asserted-by":"publisher","DOI":"10.1007\/s10910-012-0033-7"},{"key":"ref005","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2105-6-233"},{"key":"ref006","doi-asserted-by":"publisher","DOI":"10.1137\/140976649"},{"key":"ref007","first-page":"1","author":"Altman A.","year":"2005","journal-title":"Proceedings of the 6th ACM Conference on Electronic Commerce (EC);"},{"key":"ref008","doi-asserted-by":"publisher","DOI":"10.1016\/0004-3702(94)00041-X"},{"key":"ref009","doi-asserted-by":"publisher","DOI":"10.1007\/11518655_33"},{"key":"ref010","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijar.2018.11.019"},{"key":"ref011","doi-asserted-by":"publisher","DOI":"10.1017\/S0269888911000166"},{"key":"ref012","doi-asserted-by":"publisher","DOI":"10.1613\/jair.1411"},{"key":"ref013","doi-asserted-by":"publisher","DOI":"10.1145\/2939672.2939778"},{"key":"ref014","first-page":"4768","author":"Lundberg S.M.","year":"2017","journal-title":"Proceedings of the 31st International Conference on Neural Information Processing Systems (NeurIPS);"},{"key":"ref015","first-page":"590","author":"Dhurandhar A.","year":"2018","journal-title":"Proceedings of the 31st Conference on Neural Information Processing Systems (NeurIPS);"},{"key":"ref016","first-page":"1","author":"Wachter S.","year":"2017","journal-title":"SSRN Electronic Journal"},{"key":"ref017","doi-asserted-by":"publisher","DOI":"10.1145\/3287560.3287574"},{"key":"ref018","unstructured":"AlbiniE., LertvittayakumjornP., RagoA., ToniF., DAX: Deep Argumentative eXplanation for Neural Networks.
