The objects\u2019 quality is often calculated based on their historical information, such as selected records or rating scores. Usually high quality products obtain higher average ratings than low quality products regardless of rating biases or errors. However, many empirical cases demonstrate that consumers may be misled by rating scores added by unreliable users or deliberate tampering. In this case, users\u2019 reputation, that is, the ability to rate trustily and precisely, makes a big difference during the evaluation process. Thus, one of the main challenges in designing reputation systems is eliminating the effects of users\u2019 rating bias. To give an objective evaluation of each user\u2019s reputation and uncover an object\u2019s intrinsic quality, we propose an iterative balance (IB) method to correct users\u2019 rating biases. Experiments on two datasets show that the IB method is a highly self\u2010consistent and robust algorithm and it can accurately quantify movies\u2019 actual quality and users\u2019 stability of rating. Compared with existing methods, the IB method has higher ability to find the \u201cdark horses,\u201d that is, not so popular yet good movies, in the Academy Awards.<\/jats:p>","DOI":"10.1155\/2018\/4325016","type":"journal-article","created":{"date-parts":[[2018,2,13]],"date-time":"2018-02-13T23:32:27Z","timestamp":1518564747000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Eliminating the Effect of Rating Bias on Reputation Systems"],"prefix":"10.1155","volume":"2018","author":[{"given":"Leilei","family":"Wu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuoming","family":"Ren","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2323-163X","authenticated-orcid":false,"given":"Xiao-Long","family":"Ren","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianlin","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2156-0432","authenticated-orcid":false,"given":"Linyuan","family":"L\u00fc","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,2,13]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/445489a"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1171990"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2015.7010514"},{"key":"e_1_2_9_4_2","volume-title":"Information Systems: Foundation of E-Business","author":"Alter S.","year":"2001"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physrep.2012.02.006"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1088\/1367-2630\/16\/6\/063057"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/srep11404"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1145\/355112.355122"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physrep.2016.06.007"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2011.942344"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0112022"},{"key":"e_1_2_9_12_2","doi-asserted-by":"publisher","DOI":"10.1209\/0295-5075\/90\/48006"},{"key":"e_1_2_9_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physa.2014.01.046"},{"key":"e_1_2_9_14_2","doi-asserted-by":"publisher","DOI":"10.1142\/S0129183113500551"},{"key":"e_1_2_9_15_2","doi-asserted-by":"publisher","DOI":"10.1209\/epl\/i2006-10204-8"},{"key":"e_1_2_9_16_2","doi-asserted-by":"publisher","DOI":"10.1209\/0295-5075\/94\/48002"},{"key":"e_1_2_9_17_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0097146"},{"key":"e_1_2_9_18_2","article-title":"Filtering out unfair ratings in bayesian reputation systems","author":"Whitby A.","year":"2004","journal-title":"Proc 7th Int Workshop on Trust in Agent Societies"},{"key":"e_1_2_9_19_2","doi-asserted-by":"crossref","unstructured":"YuB.andSinghM.
