In this paper, we propose a\n   black-box evaluation framework of the practical recommendation services.\n   Thus, we have designed user modeling process for generating synthesized user\n   models as the inputs for the recommendation services. User models (i.e., a\n   set of user ratings) have been synthesized to discriminate the recommendation\n   results. Given a set of practical recommendation systems, the proposed\n   black-box testing scheme has been applied by comparing recommendation\n   results. Particularly, we focus on investigating whether the services\n   consider attribute selection.<\/jats:p>","DOI":"10.2298\/csis130226006l","type":"journal-article","created":{"date-parts":[[2014,1,3]],"date-time":"2014-01-03T11:37:09Z","timestamp":1388749029000},"page":"241-249","source":"Crossref","is-referenced-by-count":7,"title":["Black-box testing of practical movie recommendation systems: A comparative study"],"prefix":"10.2298","volume":"11","author":[{"given":"Namhee","family":"Lee","sequence":"first","affiliation":[{"name":"School of Business Administration Sogang University, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"J.","given":"Jason","family":"Jung","sequence":"additional","affiliation":[{"name":"Software Engineering Research Group (SERG) Knowledge Economy Research Alliance and Faculty of Computing Universiti Teknologi Malaysia Johor, Malaysia + Department of Computer Engineering Yeungnam University, Gyeongsan, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Selamat","sequence":"additional","affiliation":[{"name":"Software Engineering Research Group (SERG) Knowledge Economy Research Alliance and Faculty of Computing Universiti Teknologi Malaysia Johor, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dosam","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering Yeungnam University, Gyeongsan, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1078","container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:31:18Z","timestamp":1685349078000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02141400006L"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2014]]}},"URL":"https:\/\/doi.org\/10.2298\/csis130226006l","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014]]}}}
