We also introduce EPUI, an Experimental Platform for Urban Informatics. Our comparison with the state-of-the-art schemes indicates that MPG is capable of providing high-quality venues and route recommendations while incorporating seamlessly both the notion of diversity and that of serendipity.\n          <\/jats:p>","DOI":"10.1145\/3391197","type":"journal-article","created":{"date-parts":[[2020,7,7]],"date-time":"2020-07-07T12:39:34Z","timestamp":1594125574000},"page":"1-32","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Serendipity-based Points-of-Interest Navigation"],"prefix":"10.1145","volume":"20","author":[{"given":"Xiaoyu","family":"Ge","sequence":"first","affiliation":[{"name":"University of Pittsburgh, Pittsburgh, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7189-9816","authenticated-orcid":false,"given":"Panos K.","family":"Chrysanthis","sequence":"additional","affiliation":[{"name":"University of Pittsburgh, Pittsburgh, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantinos","family":"Pelechrinis","sequence":"additional","affiliation":[{"name":"University of Pittsburgh, Pittsburgh, PA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7239-2387","authenticated-orcid":false,"given":"Demetrios","family":"Zeinalipour-Yazti","sequence":"additional","affiliation":[{"name":"University of Cyprus, Nicosia, Cyprus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed A.","family":"Sharaf","sequence":"additional","affiliation":[{"name":"United Arab Emirates University, Abu Dhabi, United Arab Emirates"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2020,10]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"2015.
