Concretely speaking, web pages consist of hyperlink and contents, and web images consist of the textual and visual information. In this paper, we propose a new multi-view semi-supervised learning method, named local co-training, for web page and image classification. Local co-training employs local linear models to represent data points on each view (i.e. one attribute set), and iteratively refines them using unlabelled data with co-training strategy. In each iteration, only a part of local models that we call dominant local models needs to be incrementally updated. The method is thus efficient and fit for the learning of large-scale web data. In addition, we introduce a new measurement based on both the confidence and the disagreement to describe which unlabelled examples are \u2018good\u2019 for the enrichment of training sets. Local co-training builds a bridge between two dominant types of semi-supervised methods: graph-based methods and co-training. Experiments on web page and web image datasets demonstrate that local co-training can effectively improve the classification performance by exploiting multiple attribute sets and unlabelled data.<\/jats:p>","DOI":"10.1177\/0165551513477818","type":"journal-article","created":{"date-parts":[[2013,2,25]],"date-time":"2013-02-25T22:35:50Z","timestamp":1361831750000},"page":"289-306","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Web page and image semi-supervised classification with heterogeneous information fusion"],"prefix":"10.1177","volume":"39","author":[{"given":"Youtian","family":"Du","sequence":"first","affiliation":[{"name":"Ministry of Education Key Laboratory for Intelligent Networks and Network Security, Xi\u2019an Jiaotong University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang","family":"Su","sequence":"additional","affiliation":[{"name":"MOE KLINNS Laboratory, Xi\u2019an Jiaotong University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhongmin","family":"Cai","sequence":"additional","affiliation":[{"name":"MOE KLINNS Laboratory, Xi\u2019an Jiaotong University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaohong","family":"Guan","sequence":"additional","affiliation":[{"name":"MOE KLINNS Laboratory, Xi\u2019an Jiaotong University and Center for Intelligent and Networked Systems, Tsinghua University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,2,25]]},"reference":[{"key":"bibr1-0165551513477818","doi-asserted-by":"publisher","DOI":"10.1109\/ICCV.2007.4409066"},{"key":"bibr2-0165551513477818","doi-asserted-by":"publisher","DOI":"10.1177\/0165551510368620"},{"key":"bibr3-0165551513477818","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2008.150"},{"key":"bibr4-0165551513477818","doi-asserted-by":"publisher","DOI":"10.1145\/1027527.1027746"},{"key":"bibr5-0165551513477818","unstructured":"Rosenberg DS.
