Proceeding from the perspective of solving the problem of user interest drift, a new hybrid similarity calculation model is proposed in this paper. This model consists of two parts, on the one hand the model uses the function fitting to describe users\u2019 rating behaviors and their rating preferences, and on the other hand it employs the Random Forest algorithm to take user attribute features into account. Furthermore, the paper combines the two parts to build a new hybrid similarity calculation model for user recommendation. Experimental results show that, for data sets of different size, the model\u2019s prediction precision is higher than the traditional recommendation algorithms.<\/jats:p>","DOI":"10.1155\/2017\/4379141","type":"journal-article","created":{"date-parts":[[2017,12,4]],"date-time":"2017-12-04T18:30:47Z","timestamp":1512412247000},"page":"1-9","source":"Crossref","is-referenced-by-count":3,"title":["A Novel Hybrid Similarity Calculation Model"],"prefix":"10.1155","volume":"2017","author":[{"given":"Xiaoping","family":"Fan","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Central South University, Hunan, China"},{"name":"Hunan University of Finance and Economics, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijie","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Central South University, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangkun","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Software, Central South University, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5525-904X","authenticated-orcid":true,"given":"Zhifang","family":"Liao","sequence":"additional","affiliation":[{"name":"School of Software, Central South University, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bencai","family":"Fu","sequence":"additional","affiliation":[{"name":"School of Software, Central South University, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1007\/s10994-008-5068-4"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2010.09.141"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/CC.2017.8010964"},{"key":"8","first-page":"396","volume-title":"The impact of demographics (age and gender) and other user-characteristics on evaluating recommender systems","year":"2013"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/THMS.2016.2611825"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2016.03.006"},{"issue":"2","key":"12","first-page":"149","volume":"12","year":"2014","journal-title":"IADIS International Journal on WWW\/Internet"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2016.01.004"},{"issue":"6","key":"16","year":"2015","journal-title":"Journal of Taiyuan University of Technology"},{"issue":"2","key":"21","first-page":"16","volume":"35","year":"2014","journal-title":"Journal on Communications"},{"issue":"5","key":"24","first-page":"520","volume":"46","year":"2010","journal-title":"Journal of Nanjing University (Natural Sciences)"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1109\/TSC.2016.2528246"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2017.2756826"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.13229\/j.cnki.jdxbgxb201401024"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2007.07.024"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2013.11.006"}],"container-title":["Scientific Programming"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2017\/4379141.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2017\/4379141.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2017\/4379141.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,12,4]],"date-time":"2017-12-04T18:30:50Z","timestamp":1512412250000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/sp\/2017\/4379141\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":16,"alternative-id":["4379141","4379141"],"URL":"https:\/\/doi.org\/10.1155\/2017\/4379141","relation":{},"ISSN":["1058-9244","1875-919X"],"issn-type":[{"value":"1058-9244","type":"print"},{"value":"1875-919X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
