In recent years, network based recommendation algorithms have demonstrated much better performance than the standard collaborative filtering methods. However, most of network based algorithms do not give a high enough weight to the influence of the target user\u2019s nearest neighbors in the resource diffusion process, while a user or an object with high degree will obtain larger influence in the standard mass diffusion algorithm. In this paper, we propose a novel preferential diffusion recommendation algorithm considering the significance of the target user\u2019s nearest neighbors and evaluate it in the three real-world data sets: MovieLens 100k, MovieLens 1M, and Epinions. Experiments results demonstrate that the novel preferential diffusion recommendation algorithm based on user\u2019s nearest neighbors can significantly improve the recommendation accuracy and diversity.<\/jats:p>","DOI":"10.1155\/2017\/1386461","type":"journal-article","created":{"date-parts":[[2017,5,4]],"date-time":"2017-05-04T17:01:04Z","timestamp":1493917264000},"page":"1-7","source":"Crossref","is-referenced-by-count":2,"title":["A Novel Preferential Diffusion Recommendation Algorithm Based on User\u2019s Nearest Neighbors"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2323-8033","authenticated-orcid":true,"given":"Fuguo","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Information Technology, Jiangxi University of Finance & Economics, Nanchang 330013, China"},{"name":"Research Institution for Information Resource Management, Jiangxi University of Finance & Economics, Nanchang 330013, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4053-7051","authenticated-orcid":true,"given":"Yehuan","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information Technology, Jiangxi University of Finance & Economics, Nanchang 330013, China"}]},{"given":"Qinqiao","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Information Technology, Jiangxi University of Finance & Economics, Nanchang 330013, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1000488107"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physrep.2012.02.006"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1145\/245108.245126"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2005.99"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.76.046115"},{"issue":"4","key":"7","volume":"90","year":"2010","journal-title":"Europhysics Letters"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1209\/0295-5075\/105\/58002"},{"issue":"6","key":"9","volume":"83","year":"2011","journal-title":"Physical Review E"},{"issue":"10","key":"10","volume":"99","year":"2007","journal-title":"Physical Review Letters"},{"issue":"3","key":"11","volume":"84","year":"2011","journal-title":"Physical Review E"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/j.physa.2016.02.021"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1209\/0295-5075\/100\/58005"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1088\/1367-2630\/11\/12\/123008"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1209\/0295-5075\/81\/58004"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1209\/0295-5075\/92\/28002"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2015.03.013"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2013.168"}],"container-title":["International Journal of Digital Multimedia Broadcasting"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2017\/1386461.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2017\/1386461.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2017\/1386461.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,5,4]],"date-time":"2017-05-04T17:01:18Z","timestamp":1493917278000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/ijdmb\/2017\/1386461\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":17,"alternative-id":["1386461","1386461"],"URL":"https:\/\/doi.org\/10.1155\/2017\/1386461","relation":{},"ISSN":["1687-7578","1687-7586"],"issn-type":[{"type":"print","value":"1687-7578"},{"type":"electronic","value":"1687-7586"}],"subject":[],"published":{"date-parts":[[2017]]}}}
